How to Build a House in NZ - The Complete Blueprint

Your Complete Guide to Building Your Dream Home in New Zealand

Introduction

If you're planning to build a new home in New Zealand, you're about to embark on one of the biggest financial and emotional investments of your life. Done right, it's exciting. Done wrong, it's a nightmare of budget blowouts, builder disputes, and decisions you wish you'd made differently.

This guide exists because most first-time builders in New Zealand face the same preventable problems:

Budget overruns of 15-25% from variations they didn't see coming
3-6 month delays beyond the original timeline
Dozens of decisions they weren't prepared to make when the builder needed them
At least one major regret about something they "figured they'd decide later"

None of this happens because of bad builders or bad luck. It happens because there's a gap between what first-time builders think the process involves and what it actually requires.

This guide closes that gap.

You'll learn exactly what to decide, when to decide it, and how to protect yourself at every stage - from choosing your section to moving in. Everything in here comes from real experience working with New Zealand builders, understanding the NZ building consent system, and watching hundreds of builds unfold.

Let's get started.

Chapter 1: Before You Start

The critical decisions to make before you spend a single dollar. Most people skip these - and pay for it later.

The Most Expensive Mistakes Happen in the First 60 Days

Most first-time builders start their journey in one of two ways:

They find a section they love and buy it without understanding what it costs to build on
They fall in love with a house design before they know what they can actually afford

Both approaches lead to the same problem: by the time they realize the numbers don't work, they've already spent $15,000-$30,000 on deposits, design fees, and geotech reports.

The right way to start is this: know what you can afford, what you actually want, and what's realistic to achieve before you commit to anything.

Start With Your 'Why'

Before you talk to builders, architects, or real estate agents, answer this question:

Why are you building instead of buying?

Be honest. Common answers:

"I can't find an existing home in the location I want"
"I want a home designed for how we actually live"
"I want energy efficiency and modern systems"
"I want to control the quality of materials and finishes"
"I want a specific section or view"

Your answer matters because it determines what you should prioritize - and what you can compromise on. If you're building because you can't find the right location, you need to start with the section, not the house design. If you're building for energy efficiency, you need to budget for double glazing, insulation above code minimum, and a heat pump from day one.

Define Your Non-Negotiables

Most builders will ask you what you want. That's the wrong question to start with.

The right question is: What do you absolutely need, and what can you live without?

Break your list into three categories:

Must-Haves (Non-Negotiable)

Things you will not compromise on, even if the budget is tight. Examples:

4 bedrooms (growing family)
Double garage (two vehicles)
North-facing living areas (sun all day)
Accessible bathroom (elderly parent moving in)
Home office with door (work from home)

Nice-to-Haves (Negotiable)

Things you want, but could cut if necessary. Examples:

Walk-in wardrobe in master bedroom
Butler's pantry
Deck off the living room
Separate laundry (vs. combined laundry/bathroom)

Don't-Needs (Skip Entirely)

Things you don't need and won't pay for. Examples:

Formal dining room
Bathtub in the master ensuite
Second living area
High-end appliances included in the build

This list prevents scope creep. When your architect shows you a design with a butler's pantry and it blows the budget, you already know it's negotiable.

Understand the True Cost of Building in NZ

Most first-time builders underestimate what it costs to build in New Zealand - not because they miscalculate the house, but because they forget everything else.

Here's what a $500,000 build actually costs:

Item	Cost (Approx.)
House construction (builder's contract)	$500,000
Building consent fees	$3,000-$5,000
Geotech report	$2,000-$4,000
Architectural plans	$8,000-$15,000
Engineering (structural, drainage)	$3,000-$6,000
Landscaping, driveway, fencing	$20,000-$40,000
Connections (power, water, wastewater)	$5,000-$15,000
Curtains, blinds, heat pump	$8,000-$12,000
Retaining walls (if required)	$10,000-$50,000
Total Project Cost	$559,000-$647,000

A $500,000 house is a $600,000+ project.

If your bank approved you for $550,000, you're already $50,000-$100,000 short - and that's before a single variation.

The 20% Rule

As a rule of thumb, add 20% to your builder's quote to estimate your true all-in project cost. That covers consent fees, services, landscaping, geotech, engineering, and the inevitable variations.

If you can't afford the 20% buffer, you can't afford the build.

Get Pre-Approved (Properly)

Most first-time builders get pre-approved for a mortgage before they have architectural plans. That pre-approval is based on the bank's estimate of what the finished home will be worth - not what it costs to build.

Here's the problem: if the bank values your finished home at $650,000 and will lend you 80%, that's $520,000. But if it costs $600,000 to build, you need $80,000 cash for the 20% deposit plus another $80,000 to cover the gap between what you're borrowing and what it costs.

Talk to your bank early. Ask:

What's the maximum they'll lend for a new build on this section?
What deposit do they require?
Do they cover the full construction cost, or just 80% of the end valuation?
What's the process for progress payments during the build?

Get this clarity before you pay an architect.

Decide: Project Manage Yourself or Use a Builder's Package?

You have two main paths in New Zealand:

Option 1: Builder's Package (Turnkey)

You hire one builder who manages the entire project - design, consent, subcontractors, materials, everything. You get one quote, one contract, and one point of contact.

Pros:

Simple
Builder carries the risk
Fixed price (if you lock in specs)

Cons:

Less control over subcontractors
Builder's markup on everything
Harder to make changes mid-build

Best for: First-time builders who want simplicity and are willing to pay a bit more for it.

Option 2: Owner-Builder or Separate Contracts

You hire an architect, get consent yourself, and contract with individual trades (foundations, framing, plumbing, electrical, etc.). You act as the project manager.

Pros:

Potentially cheaper (no builder's markup)
Full control over every trade and material
Can stage the build over time if cash flow is tight

Cons:

You carry all the risk
Requires construction knowledge and time
Coordinating 10+ trades is a full-time job
Harder to get bank financing

Best for: Experienced builders, people in the construction industry, or those with significant time and risk tolerance.

Most first-time builders should go with Option 1. You'll pay a bit more, but you'll sleep better.

Timeline Expectations

A typical new build in New Zealand takes:

Design and consent: 3-6 months
Construction: 6-12 months (depending on size and complexity)
Total from first meeting to move-in: 12-18 months

If someone promises you a 4-month build, be skeptical. Delays happen - weather, subcontractor availability, material supply, consent inspections. Plan for the upper end of the timeline, not the lower.

What You Should Have Before You Talk to Builders

Clear budget (including the 20% buffer)
List of must-haves, nice-to-haves, and don't-needs
Section secured or shortlisted (know the size, orientation, contours, covenants)
Bank pre-approval (ideally with a builder-friendly mobile lender)
Realistic timeline (when you need to move in, and why)

If you have these five things, you're ready to start talking to builders. If you don't, pause and get them sorted. Every dollar you spend before this point is a risk.

Chapter 2: Choosing Your Section

How to evaluate a section beyond just price - orientation, covenants, geotech, and the hidden costs most buyers miss.

The Section Shapes Everything

Your section determines:

How much sun your home gets
What you can and can't build (council rules, covenants, size limits)
How much extra you'll pay for earthworks, retaining, and drainage
Whether you can build your dream home or a compromised version of it

Most first-time builders choose a section based on price and location. That's not enough.

What to Check Before You Make an Offer

1. Orientation (Sun and Wind)

In New Zealand, north-facing living areas get sun all day. South-facing living areas are cold and dark.

When you visit the section:

Stand where the house will sit
Note where the sun is at different times of day
Check the prevailing wind direction (usually westerly in most of NZ)

If the section faces south, you'll either:

Accept a darker, colder home, or
Pay extra for larger windows, more heating, and artificial lighting

North or north-west is ideal. East is acceptable (morning sun). South is a compromise.

2. Contours and Slope

Flat sections are cheaper to build on. Sloped sections cost more.

Why? Because you'll pay for:

Earthworks (cut and fill to create a flat building platform)
Retaining walls (to hold back the earth)
Longer driveways (if the house sits higher than the road)
Drainage (to manage water runoff)

A geotech report will tell you what's required. Budget $15,000-$50,000 extra for a sloped section, depending on severity.

3. Geotechnical Conditions

Before you buy, get a geotech report. It tells you:

What's under the topsoil (clay, rock, fill, peat)
What foundation type you'll need (concrete slab, piles, deep footings)
Whether the ground is stable or prone to movement

If the report says "deep piles required," your foundation cost just jumped from $40,000 to $70,000.

Never buy a section without a geotech report.

4. Covenants and Building Lines

Most subdivisions have covenants - rules about what you can and can't build. Common restrictions:

Minimum floor area (e.g., 180m²)
Roof material and color (e.g., "no Colorsteel")
Cladding type (e.g., "minimum 60% brick or weatherboard")
Fence height and style
Building setback from boundaries (e.g., "minimum 3m from side boundary")

Read the covenants before you buy. If they require 180m² and you can only afford 140m², that section won't work.

5. Services (Power, Water, Wastewater)

Check what services are available:

Mains water or tank water?
Mains wastewater or septic tank?
Power to the boundary or will you need to pay for a new connection?

If there's no mains wastewater, budget $15,000-$30,000 for a septic system. If there's no power to the boundary, budget $5,000-$15,000 to bring it in.

6. Driveway and Access

How far is the building site from the road? If it's more than 30 meters, you'll pay extra for:

Longer driveway (concrete or metal)
Stormwater drainage along the driveway
Crossings and culverts

Budget $200-$400 per linear meter for a concrete driveway.

7. Title Type

Freehold: You own the land outright. No ongoing fees. This is what you want.
Leasehold: You lease the land from someone else. Avoid this for a new build.
Cross-lease or Unit Title: Common for subdivisions. Check what shared areas you're responsible for (driveway, fence, garden).

Freehold is cleanest.

The Hidden Costs Checklist

When you evaluate a section, add these potential costs:

Item	Typical Cost (NZD)
Geotech report	$2,000-$4,000
Retaining walls (if sloped)	$10,000-$50,000
Earthworks (cut/fill)	$8,000-$25,000
Septic system (if no mains sewer)	$15,000-$30,000
Water tank (if no mains water)	$5,000-$12,000
Power connection (if not to boundary)	$5,000-$15,000
Driveway (concrete, 30m)	$9,000-$15,000
Fencing (boundary)	$8,000-$15,000

A "cheap" section can easily cost you $50,000+ more than a flat, serviced section that's $40,000 more expensive.

Questions to Ask the Seller or Agent

Is there a geotech report available?
What are the building covenants and rules?
Are all services to the boundary (power, water, wastewater)?
What's the building setback from boundaries?
Is there a title plan showing easements or shared access?
What did the last person who built here pay for foundations/earthworks?

If they don't know, that's a red flag. Do your own due diligence.

The Section Decision Matrix

Use this to compare sections:

Factor	Weight	Section A	Section B
Orientation (north-facing)	High	8/10	5/10
Flat or minimal slope	High	9/10	4/10
Services to boundary	High	10/10	7/10
Price	Medium	6/10	9/10
Location/neighborhood	Medium	8/10	8/10
Size	Low	7/10	9/10

Multiply each score by its weight (High=3, Medium=2, Low=1) and total it. The section with the highest score is your best bet.

Don't Fall in Love Too Early

The biggest mistake first-time buyers make is falling in love with a section before they know what it costs to build on.

Get the geotech report. Get a builder to walk the site. Get a rough quote for earthworks and retaining. Then decide.

A $400,000 section that costs $50,000 to prepare is worse than a $450,000 section that's ready to build on.

Chapter 3: Setting Your Budget

The real cost of building in NZ - including the line items nobody tells you about until it's too late.

Why Most Build Budgets Are Wrong

Most first-time builders create their budget like this:

Get pre-approved by the bank for $X
Assume that's what they can spend
Find a builder who quotes close to $X
Sign the contract
Run out of money 6 months later

The problem? They forgot about:

The 20% of costs outside the builder's contract
Variations (because they hadn't locked in specs)
Landscaping, fencing, driveways
Curtains, blinds, heat pumps
Paying rent while the build happens

A realistic budget includes all of this from day one.

The Full Build Budget Template

Here's what a complete new build budget looks like in New Zealand for a $500,000 house:

Land and Prep

Item	Cost (NZD)
Section purchase	$250,000
Geotech report	$3,000
Earthworks and retaining	$20,000
Subtotal	$273,000

Design and Consent

Item	Cost (NZD)
Architectural plans	$12,000
Structural engineering	$4,000
Building consent fee	$4,000
Subtotal	$20,000

Construction

Item	Cost (NZD)
Builder's contract (house only)	$500,000
Variations (10% buffer)	$50,000
Subtotal	$550,000

Services and Site Work

Item	Cost (NZD)
Driveway (concrete, 25m)	$12,000
Fencing (boundary)	$10,000
Landscaping (basic)	$15,000
Water, power, wastewater connections	$8,000
Subtotal	$45,000

Fit-Out and Extras

Item	Cost (NZD)
Curtains and blinds	$6,000
Heat pump	$5,000
Appliances (if not included)	$8,000
Letterbox, clothesline, exterior lighting	$2,000
Subtotal	$21,000

TOTAL PROJECT COST | $909,000

That's nearly double the builder's quote.

If your bank approved you for $800,000 at 80% LVR (loan-to-value ratio), you can borrow $640,000. That leaves you with a $269,000 cash gap to cover from savings.

Most people don't have that. So they cut things, delay landscaping, skip the heat pump, and live with builder-grade everything.

Plan for the real number from day one.

The Three-Budget System

I recommend creating three budgets:

1. Minimum Viable Budget (Must-Haves Only)

This is the absolute minimum you can build and move in. No landscaping, no deck, builder-grade fixtures, no heat pump, basic flooring.

If this number exceeds what you can afford, you can't build yet.

2. Target Budget (Must-Haves + Top Nice-to-Haves)

This is what you'd like to spend. It includes the things that make the home feel complete: landscaping, upgraded kitchen, better flooring, heat pump, window treatments.

This is your planning number.

3. Maximum Budget (Everything + 10% Buffer)

This is the absolute ceiling. If costs hit this number, you stop. No more variations. No more upgrades. You finish the build and move in.

This is your risk management number.

How to Estimate Construction Costs in NZ

If you don't have a builder's quote yet, use these rough numbers:

Build Quality	Cost per m² (NZD)
Basic / Budget	$2,200-$2,800
Standard	$2,800-$3,500
High-spec	$3,500-$5,000+

For example:

150m² house at $3,000/m² = $450,000
200m² house at $3,200/m² = $640,000

This is construction only. Add 20% for everything else.

The Big Budget Killers (and How to Avoid Them)

1. Variations

Every time you change your mind after signing the contract, it costs money. A lot of money.

Examples:

Move a window: $800-$1,500
Change tile selection: $2,000-$5,000
Add a skylight: $3,000-$6,000
Move a wall: $5,000-$12,000

Solution: Lock in every selection before you sign the contract. Use the Selections Checklist (included with this guide) to make sure nothing is left as "to be confirmed."

2. Scope Creep

You start with a 150m² house. Then you add a walk-in wardrobe. Then a bigger deck. Then a butler's pantry. Suddenly it's 170m² and $60,000 over budget.

Solution: Decide on your must-haves and nice-to-haves (Chapter 1) and do not deviate. If you want to add something, you must remove something of equal cost.

3. Underestimating Site Costs

You budget $10,000 for landscaping. Then you realize you also need:

Retaining along the driveway ($8,000)
Drainage along the boundary ($4,000)
Topsoil and planting ($6,000)
Irrigation system ($3,000)

Suddenly it's $31,000.

Solution: Get three quotes for landscaping, driveway, and fencing before you finalize your budget. Use the highest quote.

4. Forgetting Financing Costs

Most builds take 9-12 months. If you're paying rent during that time, add $25,000-$40,000 to your budget.

If you're paying interest on the construction loan, add another $15,000-$25,000.

Solution: Include rent/interest in your budget from day one.

The Contingency Rule

Always include a 10% contingency in your construction budget. If the builder quotes $500,000, budget $550,000.

Why? Because:

You'll make at least a few variations
You'll discover something unexpected (e.g., rock under the foundation)
Prices will increase between quote and build (if there's a delay)

If you don't use the contingency, great - you have extra for landscaping or furniture. But if you need it and don't have it, you're stuck.

When to Walk Away

If your budget doesn't work, don't force it. Red flags:

Your minimum viable budget exceeds your maximum financing
You'd need to empty your savings and have zero emergency fund left
You're relying on selling your current home at top dollar to make the numbers work
Your partner is uncomfortable with the risk

Building a home is a huge commitment. If the numbers are tight, wait. Save more. Or look for a cheaper section, smaller design, or existing home instead.

There's no shame in pausing. There's a lot of regret in signing a contract you can't afford to finish.

Chapter 4: Design & Plans

Working with architects and designers without the budget creep. How to brief properly and avoid expensive redesigns.

The Design Phase Is Where You Control Costs

Most first-time builders think the design phase is about making the house look good. It is - but it's also where you lock in your costs.

A good design:

Fits your budget from day one
Minimizes expensive structural complexity
Uses standard materials and dimensions
Accounts for the section's orientation, slope, and covenants

A bad design looks great but costs $100,000 more than you can afford. Then you spend months revising it, paying your architect for each iteration, and delaying the build.

Get it right the first time.

Architect vs. Draftsperson vs. Designer

You have three options for getting plans drawn:

1. Registered Architect

Licensed professional. Can design anything. Expensive.

Cost: $10,000-$25,000+ (depending on complexity)
Best for: Complex designs, challenging sections, architectural ambition
Pros: Full design freedom, handles consent process, problem-solves tricky sites
Cons: Expensive, slower, might design over your budget if not managed

2. Draftsperson

Not licensed as an architect, but experienced in residential design. Cheaper.

Cost: $5,000-$12,000
Best for: Simple, standard homes on flat sections
Pros: Cheaper, faster, practical
Cons: Limited problem-solving for complex sites, may not get consent approval without architectural input

3. Builder's In-House Designer

Many builders offer design as part of their package.

Cost: $3,000-$8,000 (often included in builder's package price)
Best for: Turnkey builds, simple plans, first-time builders who want everything managed
Pros: Seamless handoff from design to build, builder knows what they're quoting
Cons: Less design flexibility, builder controls the process

Recommendation for first-time builders: If your section is flat and you want a simple, standard home, use a draftsperson or your builder's in-house designer. If your section is sloped, has tricky access, or you want something unique, hire an architect.

How to Brief Your Designer

Most people walk into the first meeting and say "we want a 4-bedroom house." That's not enough.

A good brief includes:

1. Budget (Total Construction Budget)

Be honest. If you can afford $450,000 for construction, say so. Don't say $500,000 and hope for the best.

Your designer should design to your budget, not show you a dream home and then value-engineer it down.

2. Must-Haves and Nice-to-Haves

List from Chapter 1. Must-haves go in the design. Nice-to-haves are included only if the budget allows.

3. How You Actually Live

Forget Pinterest. Think about your real daily life:

Do you cook every night or eat out?
Do you work from home? Need a dedicated office?
Do you entertain often? Need open-plan living?
Do you have young kids? Need visibility from kitchen to living area?
Do you have aging parents who might move in? Need a bedroom and bathroom on the ground floor?

Design for your life, not someone else's.

4. Section Constraints

Provide your designer with:

Section size and dimensions
Orientation (where is north?)
Slope and contours
Covenants (size limits, setbacks, materials)
Geotech report (foundation recommendations)

They'll use this to position the house optimally.

5. Style Preferences

Don't say "modern." Show examples:

"I like large windows and high ceilings"
"I want weatherboard cladding, not brick"
"I prefer a single-story, not two-story"
"I want a gable roof, not flat"

Bring photos of homes you like, but focus on the features you like, not the whole house.

The First Concept Design

Your designer will come back with a concept design - usually a floor plan and basic elevations (what the house looks like from outside).

At this stage, check:

1. Does It Fit the Budget?

Ask your designer for a rough cost estimate ($/m²). If the design is 180m² and they estimate $3,200/m², that's $576,000 - which might blow your $500,000 budget.

If it's over, revise now. Don't wait until you get a builder's quote.

2. Does It Capture the Sun?

In New Zealand, living areas should face north. Bedrooms can face east (morning sun) or south (less important). Garages and laundries can face anywhere.

If your living room faces south, ask why. There might be a good reason (view, covenant, access), but if not, rotate the design.

3. Is It Practical?

Walk through the floor plan mentally:

Can you see the front door from the driveway?
Can you carry groceries from the car to the kitchen without walking through the whole house?
Is the laundry near the bedrooms (where the dirty clothes are)?
Is there a toilet near the living area (for guests)?
Can you supervise kids in the living area while cooking?

If the flow doesn't work, say so now.

4. Does It Meet Covenants?

Check the floor area, roof pitch, setbacks, and materials against your covenants. If the design violates a covenant, the council will reject your consent application - or the covenant body will force you to rebuild.

Avoiding Expensive Redesigns

The most expensive mistake is approving a concept design too early, then realizing it doesn't work once you see the detailed plans.

Before you approve the concept:

Walk the section with the plans. Stand where the house will sit. Visualize the views, the sun, the access.
Share the plans with your partner. Make sure you both agree. Disagreements after approval cost money.
Get a rough builder's quote. Some builders will give a ballpark estimate from concept plans. If it's over budget, revise before going to detailed design.
Check every room size. A 10m² bedroom sounds fine on paper. It's tiny in real life. Use tape to mark out room sizes on the ground if you need to.

Once you approve the concept, your designer moves to detailed plans (the ones you submit for consent). Changes after this point cost $500-$2,000 per revision.

Standard Dimensions Save Money

Builders price based on materials. Materials come in standard sizes:

Timber framing: 2.4m and 4.8m lengths
Plasterboard sheets: 2.4m x 1.2m
Roof trusses: designed for standard spans

If your design uses non-standard dimensions, the builder has to cut, waste, or custom-order. That costs more.

Ask your designer to use standard dimensions wherever possible. A 12m house is cheaper than a 12.3m house because the framing works out evenly.

Simple Shapes Cost Less

A square or rectangular house is cheaper to build than an L-shape, U-shape, or complex multi-level design.

Why? Because:

Simpler roof (fewer valleys, less flashing, less risk of leaks)
Less framing complexity
Fewer corners (corners are expensive)
Easier to weatherproof

If your budget is tight, keep the shape simple.

What's Included in Your Architectural Plans?

Before you pay for plans, confirm what's included. A full set should have:

Site plan (where the house sits on the section)
Floor plans (every level, with dimensions)
Elevations (north, south, east, west views)
Sections (cut-throughs showing ceiling heights, foundations)
Roof plan (pitch, materials, drainage)
Window and door schedule (sizes, types, glazing)
Specifications (materials, finishes, fixtures)

Some designers charge extra for specifications. Clarify this upfront.

Can You Use Pre-Designed Plans?

Yes. Many companies sell pre-designed house plans for $2,000-$5,000. You buy the plans, tweak them if needed, and submit for consent.

Pros:

Cheaper than custom design
Faster
Plans are proven (already consented elsewhere)

Cons:

Less customization
May not suit your section
Still need to adapt for NZ building code and local conditions

If you find a pre-designed plan that's 90% right, it's worth considering. Just make sure your builder reviews it before you buy - some pre-designed plans assume materials or techniques that don't work in NZ.

The Design Checklist

Before you finalize your plans, confirm:

Total floor area is within budget ($/m² x floor area = construction cost)
Design fits section covenants (setbacks, floor area, materials, roof)
Living areas face north (or there's a good reason they don't)
Room sizes are practical (not just "looks fine on paper")
Flow makes sense (entry to kitchen, laundry to bedrooms, etc.)
Storage is adequate (wardrobe space, linen cupboard, garage shelving)
Roof is simple (gable or hip, not complex multi-plane)
Standard dimensions used wherever possible
Window sizes suit the view and sun (not just aesthetic)
Plans include full specifications (so builders can quote accurately)

If you can tick all these boxes, you're ready to submit for consent.

Chapter 5: Choosing Your Builder

The vetting process, red flags to watch for, and how to pick a builder you can trust with your biggest investment.

The Builder Decision Matters More Than Anything Else

You can have the perfect section, the perfect plans, and the perfect budget - but if you choose the wrong builder, the project will be a nightmare.

A good builder will:

Deliver on time and on budget
Communicate proactively
Fix problems before you notice them
Leave you with a home you're proud of

A bad builder will:

Miss deadlines by months
Hide issues until it's too late
Blame everyone else (architect, subcontractors, council, weather)
Leave you fighting over defects for years

The difference isn't always obvious from a website or a quote. You need to dig deeper.

How to Find Builders to Consider

Start with these sources:

1. Registered Master Builders (RMBA)

The RMBA is New Zealand's largest building trade association. Members must meet standards and offer guarantees.

Pros: Vetted, insured, reputable
Cons: Not all good builders are members; membership doesn't guarantee quality

Search their directory at masterbuilder.org.nz

2. Personal Recommendations

Ask friends, family, or colleagues who've built in the last 2-3 years. Not 10 years ago - the building industry changes, and so do builders.

Ask:

Would you use them again?
Were there any major issues?
Did they finish on time and on budget?
How did they handle problems?

3. Local Building Sites

Drive around your area and look for new builds in progress. If the site looks organized, tidy, and professional, note the builder's sign.

A messy site usually means a messy build.

4. Architect or Designer Referrals

If you've hired an architect or designer, ask who they've worked with successfully. They know which builders deliver quality and which ones create problems.

The Initial Meeting: What to Ask

Once you have 3-5 builders on your shortlist, meet with each one. Bring your plans (even if they're just concept plans) and your budget.

Questions to Ask Every Builder

1. How Long Have You Been Building?

You want someone with at least 5 years of experience in residential new builds (not renovations - they're different skill sets).

2. Are You a Licensed Building Practitioner (LBP)?

In New Zealand, certain building work must be done or supervised by an LBP. Your builder should have an LBP license in the relevant category (e.g., carpentry, design).

Ask to see their LBP number and verify it at lbp.ewr.govt.nz

3. Do You Have Public Liability and Contract Works Insurance?

This protects you if something goes wrong during the build (e.g., damage to neighboring property, injury on site).

Ask for proof of insurance. If they don't have it, walk away.

4. Can You Provide References From Recent Builds?

Ask for 3 references from projects completed in the last 12 months. Not 5 years ago - recent.

Call every reference. Ask:

Did the builder finish on time?
Were there cost overruns? Why?
How did the builder handle variations and issues?
Would you hire them again?

5. What's Your Current Workload?

A builder juggling 6 projects at once won't give yours the attention it needs. Ideally, they're managing 2-3 builds simultaneously.

6. Who Are Your Subcontractors?

Most builders don't do everything themselves - they contract with plumbers, electricians, roofers, etc.

Ask:

Do you use the same subcontractors on every job?
Are they LBPs?
What happens if a subcontractor doesn't show up?

Consistency matters. A builder with a reliable team is better than one who hires whoever's cheapest that week.

7. What's Your Process for Variations?

Variations (changes to the plans or specs) are inevitable. How does the builder handle them?

Red flag: "We'll just sort it out as we go."
Good answer: "We document every variation in writing, price it before proceeding, and add it to the contract."

8. What's Included in Your Quote?

Not all quotes are apples-to-apples. One builder might include landscaping, another might not. One might include council fees, another might list them separately.

Ask for a line-item breakdown so you can compare accurately.

9. What Warranties Do You Offer?

In New Zealand, builders must provide:

Master Build 10-Year Guarantee (if they're an RMBA member)
Statutory warranties under the Building Act (reasonable skill, suitable materials, compliance with building code)

Ask what's covered and for how long.

10. Can I Visit a Current Build Site?

A good builder will say yes. A builder who hesitates probably has something to hide.

When you visit, look for:

Tidy site (materials stacked, rubbish removed)
Safety measures (barriers, signage)
Subcontractors working (not an empty site)
Quality of work (straight lines, clean cuts, attention to detail)

Red Flags to Watch For

Walk away if the builder:

1. Won't Provide References

If they've been building for years but can't give you three recent references, something's wrong.

2. Pressures You to Sign Quickly

"This price is only good for 48 hours" or "I have another client ready to take this slot."

Good builders don't need to pressure you. They have enough work.

3. Quotes Significantly Lower Than Others

If three builders quote $500,000-$520,000 and one quotes $420,000, there's a reason.

Either they've missed something, they're using cheaper materials, or they plan to hit you with variations later.

4. Doesn't Ask About Your Budget or Plans

A good builder wants to understand what you're trying to achieve. A bad builder just wants to win the contract.

5. Badmouths Other Builders or Subcontractors

"Every other builder in town is rubbish" is a red flag. It suggests they blame others when things go wrong.

6. Doesn't Have Insurance or an LBP License

This is non-negotiable. Don't even consider them.

7. Has a String of Negative Reviews or Legal Disputes

Google their name + "review" or check the Disputes Tribunal records. One bad review might be an outlier. Five is a pattern.

8. Changes the Quote After You Ask Questions

"Oh, you wanted the deck included? That's extra."

A good quote is comprehensive from the start.

Comparing Quotes: It's Not Just About Price

You'll get quotes ranging from $450,000 to $550,000 for the same house. How do you compare them?

Create a Comparison Spreadsheet

Item	Builder A	Builder B	Builder C
Base construction	$480,000	$500,000	$465,000
Includes landscaping?	No	Yes ($15k)	No
Includes driveway?	No	Yes ($12k)	No
Includes fencing?	No	No	Yes ($10k)
Council fees included?	Yes	Yes	No ($4k)
Timeline (months)	10	9	12
Warranty	10-year RMBA	10-year RMBA	6-year statutory
Payment terms	Progress payments	Monthly	50% upfront
Adjusted Total	$484,000	$500,000	$479,000

Builder B looks more expensive, but includes landscaping and driveway. Builder C is cheapest but has a longer timeline, no RMBA guarantee, and requires 50% upfront (risky).

Once you adjust for what's included, the real comparison becomes clear.

Payment Terms: What's Fair?

Most NZ builders use progress payments tied to stages:

Deposit (10%): Paid on signing the contract
Foundations (15%): Paid after foundation inspection passes
Frame and roof (25%): Paid after framing inspection passes
Lock-up (20%): Paid when house is weathertight (windows, doors, roof on)
Fix-out (20%): Paid when plumbing, electrical, insulation complete
Completion (10%): Paid after final inspection and handover

This protects both parties. You pay as work is completed, and the builder has cash flow to keep the project moving.

Red Flags in Payment Terms

50%+ upfront: Too risky. If the builder goes bankrupt, you've lost half your money.
Final payment before defects are fixed: You should withhold 5-10% until all defects are remedied.
No payment schedule tied to inspections: You should only pay after council inspections pass, not just when the builder says they're done.

The Builder Interview Checklist

Before you commit, make sure you've:

Met the builder in person
Verified their LBP license
Confirmed they have insurance (public liability + contract works)
Called at least 3 references
Visited a current or recent build site
Reviewed a line-item quote breakdown
Confirmed what's included and what's extra
Asked about their variation process
Checked online reviews and disputes
Compared quotes on an apples-to-apples basis
Confirmed payment terms are fair and staged

If you can tick every box, you've done your due diligence.

Trust Your Gut

The builder you choose will be in your life for 9-12 months. You'll talk to them weekly (sometimes daily). You need to trust them.

If something feels off - they're evasive, dismissive, or overpromising - listen to that instinct.

A slightly more expensive builder you trust is better than a cheap builder who makes you nervous.

What Happens After You Choose?

Once you've selected a builder, the next step is signing the contract. That's Chapter 6.

Before you sign anything, make sure you understand every clause. A building contract is legally binding, and getting out of it later is expensive (or impossible).

Chapter 6: Understanding Your Contract

Fixed price vs. cost-plus, PC sums, provisional sums, and variations - what they mean and how to protect yourself.

The Building Contract Is Your Safety Net (or Your Trap)

Your building contract defines:

What gets built
How much it costs
When it's completed
Who's responsible for what
What happens when things go wrong

If the contract is clear, comprehensive, and fair, you're protected. If it's vague, one-sided, or missing critical details, you're at risk.

Most first-time builders sign contracts without fully understanding them. Then, six months into the build, they discover:

The quote didn't include the deck
Variations cost 50% more than expected
The completion date isn't enforceable
The builder can walk away with minimal penalty

Read the contract. Understand it. Get legal advice if needed. Don't sign until you're certain.

Fixed Price vs. Cost-Plus: What's the Difference?

There are two main contract types in New Zealand:

1. Fixed Price (Lump Sum)

The builder quotes a total price for the entire build. You pay that amount, regardless of what it actually costs the builder.

Example: Builder quotes $500,000. Even if materials cost more or the build takes longer, you still pay $500,000 (unless you make variations).

Pros:

Certainty: You know the total cost upfront
Builder carries the risk of cost overruns
Easier to secure bank financing

Cons:

Price is usually higher (builder adds a buffer for risk)
Less flexibility for changes
Builder might cut corners to protect their margin

Best for: First-time builders who want cost certainty and aren't planning many changes.

2. Cost-Plus (Prime Cost + Margin)

The builder charges you for actual costs (materials, labor, subcontractors) plus a margin (usually 10-20%) for profit and overhead.

Example: Builder estimates $500,000, but the actual cost is $520,000. You pay $520,000 + 15% margin = $598,000.

Pros:

More transparency (you see actual costs)
Easier to make changes (no variation markup)
Builder has less incentive to cut corners

Cons:

Total cost is uncertain
You carry the risk of cost overruns
Harder to secure bank financing (banks prefer fixed price)

Best for: Experienced builders, high-spec custom homes, or builds where scope is likely to change.

Recommendation for first-time builders: Go with fixed price. You'll pay a bit more, but you'll sleep better.

What Should Be Included in the Contract?

A good building contract should specify:

1. Scope of Work

Exactly what's being built. This should reference:

Architectural plans (with version number and date)
Specifications (materials, fixtures, finishes)
Site plan (where the house sits on the section)

If it's not in the plans or specifications, it's not included. Don't assume.

2. Total Price and Payment Schedule

Fixed price (or cost estimate for cost-plus)
Payment schedule (deposit, progress payments, final payment)
What each payment is tied to (e.g., "foundation inspection pass")

3. Start and Completion Dates

When the builder will start and when they'll finish.

Important: Make sure there's a clause for delays outside the builder's control (weather, council delays, material shortages). But also make sure there's a penalty if the builder misses the deadline for no good reason.

4. Variations Process

How changes to the scope or specs will be handled:

How variations are requested (in writing)
How they're priced (before or after the work?)
How they're approved (both parties sign)
When payment is due

This is critical. Without a clear process, variations become a source of constant conflict.

5. Warranties and Guarantees

What warranties the builder provides:

Statutory warranties under the Building Act
Master Build 10-Year Guarantee (if applicable)
Workmanship warranty

6. Insurance

Confirmation that the builder has:

Public liability insurance
Contract works insurance (covers damage to the build during construction)

7. Defects and Remediation

What happens if there are defects:

How long do you have to report them?
How quickly must the builder fix them?
What if the builder refuses or goes out of business?

8. Termination Clause

What happens if you or the builder want to end the contract early:

Under what circumstances can either party terminate?
What notice is required?
Who pays for work completed to date?

PC Sums and Provisional Sums: What Are They?

Most fixed-price contracts include PC sums and provisional sums. These are estimates for items that haven't been finalized yet.

PC Sum (Prime Cost Sum)

An allowance for specific items you'll choose later (e.g., kitchen, bathroom fixtures, flooring, tiles).

Example:

PC sum for kitchen: $25,000
PC sum for bathroom tiles: $3,000

If you choose a kitchen that costs $30,000, you pay the extra $5,000 as a variation.

If you choose one that costs $22,000, you get a $3,000 credit.

The problem: Builders often set PC sums low to make the quote look cheaper. Then you choose finishes you like, and suddenly you're $20,000 over budget.

Solution: Before signing, ask the builder to show you what $25,000 buys in a kitchen. If it's builder-grade laminate and you want stone benchtops, the PC sum is too low. Renegotiate it now, not later.

Provisional Sum

An estimate for work that might be required but hasn't been scoped yet (e.g., earthworks, retaining, rock removal).

Example:

Provisional sum for earthworks: $15,000

If the actual cost is $18,000, you pay the extra $3,000.

If it's only $12,000, you get a $3,000 credit.

The problem: Provisional sums are guesses. If the builder underestimates, you're on the hook.

Solution: Get a quantity surveyor or engineer to estimate these costs before you sign. Use the higher estimate in the contract.

Variations: The Budget Killer

A variation is any change to the plans, specifications, or scope after the contract is signed.

Common variations:

Moving a window: $1,200
Upgrading benchtops from laminate to stone: $6,000
Adding a skylight: $4,500
Changing tile selection: $2,500
Moving a wall: $8,000

Variations don't just cost the material difference. The builder charges for:

Redesign (if structural)
Wasted materials (if already ordered)
Rework (if already built)
Admin and markup (usually 20-30%)

A $2,000 material upgrade can easily become a $3,500 variation.

How to Minimize Variations

Lock in every selection before you sign the contract. Use the Selections Checklist (Chapter 9) to make sure nothing is "to be confirmed."
Don't change your mind. Every change costs money. If you approved white tiles, don't switch to gray ones a month later.
Get variations priced in writing before approving. If the builder says "moving that window will be about $1,000," get it in writing. Don't approve based on a verbal estimate.
Track every variation. Keep a spreadsheet of every variation, the cost, and the approval date. This prevents disputes later.

Contract Clauses to Watch Out For

1. "Builder Has Final Say on Materials"

Some contracts say the builder can substitute materials if the specified ones aren't available.

Problem: The builder might switch to cheaper materials without your approval.

Fix: Add a clause that requires your written approval for any substitution.

2. "Price Subject to Change"

Some contracts say the price can increase if material costs rise.

Problem: You no longer have a fixed price.

Fix: Only accept this if there's a cap (e.g., "price may increase by no more than 5%").

3. "No Penalty for Delays"

Some contracts have no penalty if the builder misses the completion date.

Problem: The builder has no incentive to finish on time.

Fix: Add a liquidated damages clause (e.g., "$200/day for every day past the completion date").

4. "Builder Can Terminate at Any Time"

Some contracts let the builder walk away with minimal notice.

Problem: You're left with a half-built house and no recourse.

Fix: Require 30 days' notice and compensation for work completed + costs to finish with a new builder.

5. "Final Payment Due Before Defects Fixed"

Some contracts require full payment before you've inspected the house.

Problem: Once the builder has all the money, they have no incentive to fix defects.

Fix: Withhold 5-10% of the final payment until all defects are remedied (usually 6-12 months after handover).

Get Legal Advice (It's Worth It)

A lawyer who specializes in construction contracts will cost $500-$1,500 to review your contract. That's cheap insurance on a $500,000+ project.

They'll spot clauses that protect the builder at your expense and suggest changes.

Don't skip this step.

The Pre-Signature Checklist

Before you sign the contract, confirm:

The contract type (fixed price or cost-plus) matches what you agreed
The total price matches the quote
The payment schedule is fair and tied to inspections
The plans and specs are attached and referenced
PC sums and provisional sums are realistic (not underestimated)
The variations process is clear and in writing
There's a clause for delays and penalties
Warranties and insurance are confirmed
You've had a lawyer review the contract
Both you and your partner have read and understood it

If you can't tick every box, don't sign yet.

What Happens After You Sign?

Once the contract is signed, the builder applies for building consent (Chapter 7).

You're now locked in. Changes cost money. The clock is ticking.

This is why getting the contract right is so critical. It's the foundation of the entire project.

Chapter 7: Council Consent

The NZ building consent process, required documents, inspections, and how to avoid delays.

What Is Building Consent (and Why You Need It)?

In New Zealand, you can't legally build a new home without building consent from your local council.

Building consent is the council's way of ensuring your house:

Complies with the New Zealand Building Code
Is safe to live in
Meets local planning rules (setbacks, height limits, coverage)
Won't negatively affect neighbors or the environment

The consent process involves:

Submitting plans and documentation
Council review (checking for code compliance)
Approval (or requests for changes)
Inspections during construction
Code Compliance Certificate (CCC) at the end

Without a CCC, the house is legally unfinished - you can't sell it, rent it, or (technically) live in it.

Who Applies for Consent?

Usually, the builder applies for consent on your behalf (included in their package).

If you're owner-building or using separate contracts, you'll apply yourself.

Either way, make sure:

The applicant is listed correctly (usually the property owner)
The plans are final (not concept plans)
All required documents are included (more on this below)

What Documents Are Required?

A complete consent application includes:

1. Architectural Plans

Full working drawings showing:

Site plan (house location on the section)
Floor plans (all levels)
Elevations (north, south, east, west views)
Roof plan
Sections (cut-throughs showing heights and structure)

2. Specifications

Detailed list of materials and finishes:

Foundation type (slab, piles, etc.)
Framing timber (e.g., H1.2 treated pine)
Cladding (e.g., weatherboard, brick)
Roofing (e.g., Colorsteel, tiles)
Insulation (e.g., R2.8 walls, R3.6 ceiling)
Glazing (e.g., double-glazed, Low-E)
Plumbing and drainage

3. Structural Engineering

Engineer's design and calculations for:

Foundations
Framing (if complex or multi-story)
Retaining walls
Wind and seismic loads (NZ is in an earthquake zone)

4. Geotechnical Report

Report from a geotechnical engineer detailing:

Soil composition
Bearing capacity
Foundation recommendations

5. Energy Efficiency (H1 Calculations)

Proof that the house meets the Building Code's energy efficiency requirements (Clause H1).

This usually involves thermal performance calculations showing insulation, glazing, and heating meet minimum standards.

6. Drainage Plan

Shows how stormwater and wastewater will be managed:

Stormwater disposal (soakage, council drain)
Wastewater connection (mains sewer or septic)

7. Fire Safety (if applicable)

For multi-story homes or homes close to boundaries, you may need fire safety calculations.

8. Consent Application Form (Form 1)

Council-specific form with basic details (applicant, property address, builder, etc.).

How Long Does Consent Take?

Statutory timeframe: Councils must process consent applications within 20 working days.

Reality: Most consents take 4-8 weeks, especially if the council requests further information (RFI).

Delays happen if:

Documents are incomplete
Plans don't meet code
Engineering is missing or inadequate
The council is backlogged (common in high-growth areas)

How to speed it up:

Submit a complete application (no missing documents)
Use an experienced designer/architect who knows the local council's preferences
Respond quickly to any RFI (Request for Information)
Consider using a private building consent authority (faster, but costs more)

Council Inspections During the Build

Once consent is granted, the council will inspect the build at key stages:

1. Foundation Inspection

When: After foundation is laid, before concrete is poured (for slab) or before framing starts (for piles)

What they check:

Correct depth and reinforcement
Compaction and drainage
Compliance with geotech and structural plans

Why it matters: If the foundation fails inspection, you have to fix it before proceeding. This can delay the build by weeks.

2. Framing Inspection

When: After framing is complete, before it's covered with cladding

What they check:

Timber treatment and bracing
Correct framing sizes and spacing
Structural connections (bolts, brackets)

3. Pre-Line Inspection

When: After plumbing, electrical, and insulation are in, before plasterboard goes up

What they check:

Insulation installed correctly (no gaps)
Plumbing and electrical roughed in and compliant
Moisture barriers (building wrap, flashings)

4. Final Inspection

When: After the build is 100% complete

What they check:

Everything meets consent plans and Building Code
All systems functional (plumbing, electrical, drainage)
No defects or non-compliance

Why it matters: You can't get the Code Compliance Certificate (CCC) without passing this inspection.

Common Consent Issues (and How to Avoid Them)

1. Plans Don't Match the Site

Problem: The plans show the house 3m from the boundary, but the covenant requires 4m.

Solution: Check covenants and council rules before finalizing plans.

2. Structural Engineering Is Inadequate

Problem: The council wants more detail on bracing or seismic design.

Solution: Hire a qualified structural engineer (not just the builder's mate).

3. Energy Efficiency (H1) Doesn't Meet Code

Problem: The insulation or glazing doesn't meet minimum thermal performance.

Solution: Specify double glazing and insulation above code minimum (e.g., R2.8 walls, R3.6 ceiling). Get H1 calculations done before submitting.

4. Drainage Plan Is Missing or Unclear

Problem: The council doesn't approve disposal of stormwater (e.g., soakage on clay soil).

Solution: Get a drainage engineer to design a compliant system (soakage, retention, council connection).

5. Fire Safety Not Addressed

Problem: The house is too close to the boundary and needs fire-rated walls.

Solution: Check the Acceptable Solutions (C/AS1) early and design accordingly.

What If Consent Is Declined?

If the council declines your application, they'll tell you why. Common reasons:

Non-compliance with Building Code
Non-compliance with district plan (height, setbacks, coverage)
Inadequate engineering or documentation

What to do:

Review the council's reasons
Revise the plans or documentation
Resubmit (usually no additional fee if resubmitted within 6 months)

How to avoid this: Use an experienced designer and submit a complete, compliant application the first time.

Code Compliance Certificate (CCC)

The CCC is the final proof that your house was built according to the consent.

You need the CCC to:

Legally occupy the house
Sell the house
Get insurance

How to get it:

Pass the final inspection
Submit a CCC application (Form 8) with:
- Copies of all inspection records
- Producer statements (from engineers, plumbers, electricians confirming compliance)
- Warranties and guarantees
Council reviews and issues the CCC (usually within 10-20 working days)

If the council won't issue a CCC:

There are unconsented variations
Defects haven't been fixed
Inspections were missed

Fix the issues and reapply. Don't occupy the house without a CCC - it's illegal and will cause major problems if you try to sell later.

Private Consent vs. Council Consent

You have two options for building consent:

1. Council Consent (Standard)

Submit to your local council. They review and inspect.

Pros: Cheaper (council fees are usually $3,000-$5,000)
Cons: Slower, variable quality, backlogged in some areas

2. Private Building Consent Authority (BCA)

Submit to a private company accredited by MBIE to process consents.

Pros: Faster (often 2-3 weeks), more responsive
Cons: More expensive (fees $5,000-$10,000)

When to use private BCA:

You're in a hurry
Your local council is slow or difficult
You have a complex build and want expert reviewers

The Consent Checklist

Before submitting, confirm:

Architectural plans are complete and final
Specifications detail all materials and finishes
Structural engineering is included (if required)
Geotechnical report is included
Energy efficiency (H1) calculations prove compliance
Drainage plan shows compliant stormwater and wastewater disposal
Fire safety addressed (if applicable)
All documents are signed and dated
Application form (Form 1) is complete

If you can tick every box, your consent should be approved without delay.

Chapter 8: Managing Variations

How variations work in NZ builds, keeping them under control, and avoiding the budget blowout.

Variations Are Inevitable (But You Can Control Them)

No matter how well you plan, you'll make at least a few changes during the build. You'll:

See something in real life that doesn't work on paper
Change your mind about a finish
Discover an issue that requires a redesign (e.g., rock under the foundation)

This is normal. The problem isn't variations - it's uncontrolled variations.

Uncontrolled variations:

Add 15-25% to your budget
Delay the build by months
Create conflict with your builder
Leave you with a half-finished house and no money to complete it

Controlled variations:

Are priced before approval
Fit within your contingency budget
Are documented in writing
Don't delay the build

The difference is process and discipline.

What Counts as a Variation?

A variation is anything that changes the original contract:

Design Changes

Moving a wall, window, or door
Adding or removing a room
Changing the roof pitch or layout

Material or Finish Upgrades

Upgrading from laminate to stone benchtops
Switching from carpet to timber flooring
Changing tile selection

Scope Additions

Adding a deck
Adding a skylight
Upgrading to higher-spec appliances

Unforeseen Work

Rock removal during excavation
Additional drainage required
Structural changes due to site conditions

PC Sum Adjustments

Choosing a kitchen above the PC sum allowance
Choosing fixtures above the PC sum

Even small changes add up. Five $2,000 variations = $10,000 over budget.

How Variations Are Priced

Builders don't charge variations at cost. They charge:

Materials cost
Labor cost
Markup (usually 20-30% for profit and overhead)
Rework cost (if something already built needs to be undone)

Example: Upgrading benchtops

Cost Component	Amount
Stone benchtops (vs. laminate)	+$3,500
Additional labor (templating, cutting)	+$800
Builder's markup (25%)	+$1,075
Total Variation Cost	$5,375

The material difference is $3,500, but the variation costs $5,375.

If you're already over budget, that extra $1,875 might be the difference between finishing the build and running out of money.

The Variation Approval Process (How It Should Work)

A good builder will follow this process:

1. You Request a Change

You tell the builder what you want to change (e.g., "I want to move this window 1 meter to the right").

2. Builder Prices the Variation

The builder provides a written quote for the change:

Description of work
Cost breakdown (materials, labor, markup)
Impact on timeline (if any)

3. You Approve or Decline

You review the quote and either:

Approve in writing (sign the variation form)
Decline (no change, original contract stands)
Negotiate (ask for alternatives or revisions)

4. Builder Completes the Work

Once approved, the builder does the work and adds the cost to the contract.

5. Payment

The variation cost is added to the next progress payment (or invoiced separately).

Critical rule: Never approve a variation without a written price. "We'll sort it out later" always costs more than you expect.

Red Flags in the Variation Process

1. Builder Prices Variations After the Work Is Done

Problem: You can't negotiate or decline. You're stuck paying whatever they charge.

Fix: Require all variations to be priced and approved in writing before work starts.

2. Builder Verbally Quotes a Price, Then Charges More

Problem: "I said it would be about $1,500" becomes a $2,800 invoice.

Fix: Get every variation quote in writing. Verbal quotes don't count.

3. Builder Claims Everything Is a Variation

Problem: Things that should have been included in the original contract are charged as variations.

Fix: Review the original contract and plans. If it was in the scope, it's not a variation.

4. Builder Bundles Variations Without Itemization

Problem: Invoice says "Variations: $18,000" with no breakdown.

Fix: Require an itemized list of every variation, with individual costs.

How to Minimize Variations

1. Lock In Every Selection Before Signing the Contract

Use the Selections Checklist (Chapter 9) to finalize:

Kitchen (cabinets, benchtops, appliances)
Bathrooms (tiles, fixtures, vanity)
Flooring (carpet, timber, tile - every room)
Paint colors (interior and exterior)
Fixtures (door handles, light switches, taps)
Windows and doors (sizes, types, glazing)

If it's "to be confirmed" in the contract, it's a variation waiting to happen.

2. Don't Change Your Mind

Once you've approved something, stick with it. Every change costs money.

If you approved white subway tiles, don't switch to herringbone marble a month later.

3. Visit the Site Regularly (But Don't Interfere)

Weekly site visits help you catch issues early, before they're built wrong and need to be redone.

But don't tell subcontractors what to do. If you see a problem, tell the builder. They'll handle it.

4. Build a Contingency Into Your Budget

Even with perfect planning, you'll have 3-5 variations. Budget 10% of the construction cost for this.

If the builder quotes $500,000, set aside $50,000 for variations.

If you only spend $20,000, you have $30,000 left for landscaping or furniture. But if you need $50,000 and don't have it, the build stops.

Tracking Variations

Keep a spreadsheet of every variation:

Date	Description	Quoted Cost	Approved?	Paid?
15 Feb	Move kitchen window 1m left	$1,200	Yes	Yes
3 Mar	Upgrade to stone benchtops	$5,375	Yes	No
12 Mar	Add skylight to bathroom	$4,200	No	N/A
20 Mar	Change tile selection	$2,800	Yes	No
Total		$13,575

This prevents:

Disputes ("I never approved that!")
Double-billing (builder charges you twice for the same variation)
Budget blowout (you see the total rising and can stop before it's too late)

What If You Can't Afford a Variation?

If the builder says "We found rock - we need an extra $15,000 for excavation," and you don't have $15,000, you have options:

1. Negotiate

Ask if there's a cheaper solution:

Can we work around the rock instead of removing it?
Can we reduce the excavation depth?

2. Cut Something Else

Remove a nice-to-have from the build to fund the must-have variation:

Skip the deck
Downgrade the kitchen
Use cheaper flooring

3. Pause the Build

If you can't afford to proceed, pause the build, save more money, and resume later.

This is better than going into debt or forcing the builder to cut corners.

4. Dispute It (If It's Not a Valid Variation)

If the variation is the builder's fault (e.g., they didn't check the geotech report and should have known about the rock), you may not be liable.

Review the contract and get legal advice.

Common Variations (and What They Cost)

Variation	Typical Cost (NZD)
Move a window	$800-$1,500
Add a window	$1,200-$2,500
Move a wall (non-structural)	$3,000-$8,000
Move a wall (structural)	$8,000-$15,000
Add a skylight	$3,500-$6,000
Upgrade benchtops (laminate to stone)	$4,000-$7,000
Change tile selection	$2,000-$5,000
Upgrade flooring (carpet to timber)	$3,000-$8,000
Add a deck (20m²)	$8,000-$15,000
Excavate rock	$5,000-$20,000

Use these as rough guides when deciding whether a variation is worth it.

When Variations Are the Builder's Fault

Not all variations are your fault. Sometimes the builder made a mistake:

Examples:

Builder ordered the wrong windows
Builder built a wall in the wrong location
Builder didn't follow the plans

In these cases, you should not pay for the variation.

Review the contract and original plans. If the builder deviated without your approval, they're liable.

The Variation Management Checklist

For every variation:

Request is submitted in writing
Builder provides a written quote (itemized)
Quote includes cost breakdown and timeline impact
You review and approve in writing (or decline)
Variation is added to the tracking spreadsheet
Work is completed as quoted
Invoice matches the approved quote
Payment is made (and recorded)

If you follow this process for every variation, you'll stay in control.

Chapter 9: Selections & Finishes

Kitchen, bathrooms, flooring, fixtures, and paint - how to make decisions without blowing the budget.

Selections Are Where Budgets Explode

The construction contract is signed. The builder starts work. Then they ask:

"What kitchen do you want?"
"What tiles for the bathrooms?"
"What color paint?"
"What flooring?"

You start browsing. You fall in love with stone benchtops, imported tiles, and solid timber floors.

Suddenly, the $25,000 PC sum for the kitchen is $40,000. The $3,000 bathroom tile allowance is $7,000. The $5,000 flooring budget is $12,000.

You're $26,000 over budget - and the house isn't even framed yet.

This is the most common budget blowout in NZ builds.

The solution? Make every selection before you sign the contract. Lock in the prices. Remove the temptation.

The Selections Checklist

Here's everything you need to choose:

Kitchen

Cabinetry style and color
Benchtop material (laminate, engineered stone, granite, etc.)
Splashback (tiles, glass, stone)
Sink (undermount, drop-in, size, material)
Tapware (mixer, gooseneck, pull-out, finish)
Appliances (oven, cooktop, rangehood, dishwasher - if included)
Handles and hardware

Bathrooms (for each bathroom)

Vanity (size, style, color)
Vanity benchtop (laminate, stone)
Basin (above-counter, undermount, integrated)
Tapware (basin mixer, bath mixer, shower mixer)
Toilet (back-to-wall, close-coupled, soft-close seat)
Shower (size, tray type, screen type)
Bath (freestanding, built-in, size - if applicable)
Tiles (floor, shower, feature wall)
Mirror and lighting

Flooring

Living areas (carpet, timber, hybrid, tile)
Kitchen (tile, timber, hybrid, vinyl)
Bathrooms (tile type, size, pattern)
Bedrooms (carpet type, color, underlay)
Hallways and entrance (hard flooring, carpet)
Garage (concrete finish, coating, tiles)

Internal Finishes

Paint colors (every room, ceilings, trims)
Paint finish (flat, low-sheen, semi-gloss)
Skirting boards (height, profile, material)
Architraves (style, material)
Door hardware (handles, hinges, stoppers)
Light switches and power points (color, style)

External Finishes

Cladding (weatherboard, brick, stucco, etc.)
Cladding color
Roof material (Colorsteel, tiles, etc.)

Garage door (style, color, opener type)

Fixtures and Hardware

Internal door handles (lever, knob, finish)
Wardrobe doors and hardware
Towel rails, toilet roll holders, robe hooks
Letterbox
House numbers

If anything on this list is "to be confirmed" when you sign the contract, you're setting yourself up for variations.

How to Make Selections Without Blowing the Budget

1. Start With Your PC Sum Allowance

If the builder has allocated $25,000 for the kitchen, ask them to show you what that buys.

Go to a kitchen showroom. Say "I have $25,000. Show me what that includes."

You'll quickly learn whether the allowance is realistic.

2. Prioritize What Matters

You can't afford to upgrade everything. Choose 2-3 things that matter most to you and spend there.

Example priorities:

Kitchen benchtops (you'll see them every day for 20 years)
Bathroom tiles (cheap tiles look cheap forever)
Flooring in living areas (high-traffic, high-visibility)

Everything else? Go with builder-grade or mid-range.

3. Shop Around (But Don't Overthink It)

Get quotes from 2-3 suppliers for big-ticket items (kitchen, flooring, tiles).

But don't spend 6 months agonizing over every choice. Decision fatigue is real, and it delays the build.

Set a deadline: "We'll finalize all selections by [date]."

4. Beware of Showroom Syndrome

Showrooms display the most expensive options. The $60,000 kitchen. The $15,000 bathroom.

That's not what the PC sum covers.

Ask to see the budget range first. If you fall in love with something pricier, you'll know exactly what it costs to upgrade.

5. Use Standard Sizes

Custom sizes cost more. A standard 900mm vanity is cheaper than a custom 950mm one.

Standard tile sizes (300x300, 600x600) are cheaper than large-format or custom sizes.

Stick to standard wherever possible.

Kitchen: Where to Spend and Where to Save

Spend:

Benchtops: Engineered stone or granite looks better and lasts longer than laminate. Budget $4,000-$8,000.
Tapware: A good mixer tap (e.g., Methven, Mico) costs $300-$600 and makes a difference every day.

Save:

Cabinetry: Flat-panel doors in a neutral color (white, gray) look good and cost less than shaker-style or custom colors.
Splashback: Subway tiles ($50-$80/m²) look great and are cheaper than glass ($200-$400/m²) or stone.
Handles: Simple handles cost $5-$15 each. Designer handles cost $30-$80 each. For 20 cabinets, that's a $500-$1,300 difference.

Bathrooms: Where to Spend and Where to Save

Spend:

Tiles: Bathrooms are small, so good tiles don't cost much more. Budget $60-$100/m² for floor tiles, $40-$80/m² for wall tiles.
Shower mixer: A thermostatic mixer ($400-$700) is safer and more consistent than a standard mixer ($150-$300).

Save:

Vanity: A standard 750mm or 900mm vanity from a big-box store costs $500-$1,200. Custom vanities cost $2,000-$5,000.
Toilet: A mid-range back-to-wall toilet ($400-$700) works just as well as a designer one ($1,200-$2,500).
Mirror: A frameless mirror costs $100-$300. A custom framed mirror costs $600-$1,500.

Flooring: Where to Spend and Where to Save

Spend:

Living areas: If you want timber or hybrid, budget $80-$150/m² installed. It's high-traffic and high-visibility - worth the investment.

Save:

Bedrooms: Good carpet costs $50-$80/m² installed. You don't need premium wool ($120-$200/m²) in bedrooms.
Garage: Concrete is fine. Epoxy coating ($30-$50/m²) is optional.

Paint: The Easiest Way to Save (or Waste) Money

Tips:

Stick to neutral colors: White, gray, beige. They're timeless, easy to touch up, and don't limit your furniture choices.
Use one or two colors max: Painting 12 rooms in 12 different colors costs more (labor and materials).
Low-sheen for walls, semi-gloss for trims: Standard and practical.

Cost:

Professional painting: $25-$40/m² of floor area
DIY: $8-$15/m² (just paint cost)

For a 150m² house, professional painting costs $3,750-$6,000. DIY costs $1,200-$2,250.

If you're handy and have time, painting yourself saves $2,500-$4,000.

Fixtures and Hardware: Small Choices, Big Impact

Where to Save:

Power points and switches: Standard white costs $5-$10 each. Designer finishes (black, brass) cost $20-$50 each. For 50 points, that's $750-$2,000 extra.
Door handles: Standard lever handles cost $15-$30. Designer handles cost $50-$150.

Where to Spend:

Front door hardware: It's the first thing people see. A good lock and handle set ($200-$400) is worth it.

The Selection Timeline

Ideally, finalize selections before you sign the building contract.

If that's not possible, finalize them within 4 weeks of signing.

Why? Because builders order materials in bulk. If you delay, they might:

Order placeholder items (and charge you to replace them)
Hold up the build waiting for your decision
Charge rush fees for late orders

Delays cost money.

What If You Can't Decide?

If you're stuck between two options:

Go with the cheaper one. You'll forget the "nicer" option within a month.
Flip a coin. Seriously. Most selections don't matter as much as you think.
Ask your builder. They've seen hundreds of builds. They know what works.

Don't let indecision delay the build.

The Selections Budget Tracker

Track every selection and its cost:

Item	PC Sum	Actual Cost	Difference
Kitchen	$25,000	$28,500	+$3,500
Bathroom 1 tiles	$2,500	$3,200	+$700
Flooring (living)	$8,000	$7,200	-$800
Paint (whole house)	$5,000	$4,500	-$500
Total	$40,500	$43,400	+$2,900

If you're tracking over budget, cut something before it's too late.

Chapter 10: The Build Process

From foundations to fit-out - what happens at each stage, what to watch for, and what can go wrong.

The Build Sequence (What Happens When)

A typical NZ house build follows this sequence:

Stage 1: Site Preparation (Week 1-2)

Site is pegged out (surveyor marks where the house will sit)
Temporary fencing and toilet installed
Services marked (water, power, wastewater)
Topsoil stripped and stockpiled (for landscaping later)

What to watch for:

House is positioned correctly on the section (check setbacks from boundaries)
Trees or vegetation you want to keep are protected
Services are marked so they're not damaged

Stage 2: Earthworks and Foundations (Week 2-4)

Excavation for foundations (slab, piles, or footings)
Retaining walls built (if required)
Drainage installed (stormwater, wastewater)
Foundation laid (concrete poured or piles driven)

Council inspection: Foundation inspection before concrete is poured or before framing starts.

What to watch for:

Foundation is level and square
Reinforcing steel (rebar) is in place and tied correctly
Drainage pipes slope correctly (water must flow away from the house)

What can go wrong:

Rock or unexpected ground conditions (adds cost)
Poor compaction (foundation settles later)
Inadequate drainage (water pools under the house)

Stage 3: Framing (Week 5-8)

Timber framing erected (walls, roof trusses)
Windows and doors installed
Bracing installed (for wind and earthquake resistance)
Roof installed (trusses, purlins, roofing material)

Council inspection: Framing inspection before cladding goes on.

What to watch for:

Walls are straight and square
Roof pitch is correct
Windows and doors are the right size and in the right location
Bracing is installed per the engineer's plans

What can go wrong:

Walls built in the wrong location
Windows the wrong size or style (expensive to fix)
Roof doesn't match plans (affects cladding and flashings)

Stage 4: Exterior Cladding and Weatherproofing (Week 9-12)

Building wrap (moisture barrier) installed
Cladding installed (weatherboard, brick, etc.)
Flashings installed (around windows, doors, roof junctions)
Gutters and downpipes installed
House is now "weathertight" (water can't get in)

What to watch for:

Building wrap is installed correctly (overlapped, taped, no gaps)
Flashings are installed at all junctions (window heads, base of walls)
Cladding is straight and evenly spaced
No gaps where water can enter

What can go wrong:

Poor flashing (leads to leaks years later)
Cladding not installed per manufacturer's specs (voids warranty)
Building wrap torn or missing (moisture gets into the wall cavity)

Stage 5: Plumbing, Electrical, and Insulation (Week 13-16)

Plumbing roughed in (pipes in walls and under floors)
Electrical roughed in (cables in walls, ceiling)
Insulation installed (walls, ceiling, underfloor)
Ventilation and heating ducts (if applicable)

Council inspection: Pre-line inspection before plasterboard goes up.

What to watch for:

Insulation fills the entire cavity (no gaps, no compression)
Plumbing pipes are supported and won't rattle
Electrical cables are run neatly and safely
Enough power points in every room

What can go wrong:

Insulation poorly installed (cold spots, condensation, mold)
Plumbing leaks (expensive to fix once plasterboard is up)
Not enough power points (you'll regret it later)

Stage 6: Interior Lining and Plastering (Week 17-20)

Plasterboard (Gib) installed on walls and ceilings
Joints taped and stopped (smoothed)
Cornice installed (if specified)
First coat of paint (ceiling and walls)

What to watch for:

Plasterboard joints are smooth (no ridges or bumps)
Corners are square
No visible screws or nail pops

What can go wrong:

Poor stopping (joints show through paint)
Plasterboard damaged (dents, holes)

Stage 7: Fit-Out (Week 21-24)

Kitchen installed
Bathroom vanities, toilets, showers installed
Internal doors and hardware installed
Flooring installed (carpet, timber, tile)
Final coat of paint
Light fixtures and switches installed
Plumbing fixtures connected (taps, toilets, etc.)

What to watch for:

Kitchen is level and doors close properly
Tiles are straight and grout lines are even
Flooring is smooth and transitions are neat
Paint is even (no streaks, drips, or missed spots)

What can go wrong:

Kitchen cabinets don't fit (wrong size or poor measurement)
Tiles crack during installation
Paint color doesn't match what you approved

Stage 8: Exterior and Final Touches (Week 25-28)

Driveway poured
Fencing installed
Landscaping (basic or full, depending on contract)
Final cleaning
Handover

Council inspection: Final inspection before Code Compliance Certificate.

What to watch for:

All defects from earlier stages are fixed
Everything works (lights, taps, appliances, doors)
Site is clean and rubbish removed

What can go wrong:

Builder rushes to finish and misses defects
Landscaping is incomplete or poor quality
Council finds non-compliance and delays CCC

How Long Does Each Stage Take?

Stage	Duration
Site prep	1-2 weeks
Foundations	2-3 weeks
Framing	3-5 weeks
Cladding and weatherproofing	3-4 weeks
Plumbing, electrical, insulation	3-4 weeks
Plasterboard and painting	3-4 weeks
Fit-out	3-5 weeks
Exterior and final	2-4 weeks
Total	20-31 weeks (5-8 months)

Add 2-4 months for delays (weather, material shortages, subcontractor availability, council inspections).

Realistic timeline: 9-12 months from groundwork to handover.

What Causes Delays?

1. Weather

Rain delays foundations, framing, and exterior work. You can't pour concrete in heavy rain. You can't install cladding in high wind.

Winter builds take longer than summer builds.

2. Council Inspections

If the inspector is booked out, you might wait 1-2 weeks for an inspection. If the inspection fails, you wait another 1-2 weeks for a re-inspection.

3. Material Shortages

If the supplier is out of stock (common for windows, trusses, cladding), the build stops until materials arrive.

4. Subcontractor Availability

If the plumber is sick or double-booked, the build stops until they're available.

5. Variations

Every variation adds time. Moving a wall might delay framing by a week.

What You Should Do During the Build

1. Visit the Site Weekly

Walk through once a week (more often during critical stages like framing and fit-out).

Don't:

Tell subcontractors what to do
Move materials or tools
Bring friends/family who'll get in the way

Do:

Take photos (helpful for insurance and future reference)
Note anything that doesn't look right
Ask the builder questions (not the subcontractors)

2. Attend Council Inspections (If Possible)

If you're available, attend the foundation, framing, and pre-line inspections.

You'll learn what the inspector checks and whether there are any issues.

3. Check Progress Against the Schedule

The builder should provide a schedule (e.g., "framing complete by March 15").

If they're falling behind, ask why. Is it weather? Materials? Poor planning?

4. Communicate Regularly

Weekly or fortnightly catch-ups (phone, email, or in-person) keep you informed and prevent surprises.

Ask:

What's been completed this week?
What's planned for next week?
Are we on schedule?
Any issues or delays?

5. Pay Progress Payments on Time

If the builder completes a stage and the invoice is due, pay it promptly.

Late payments delay the build (builder won't order materials until they're paid).

Red Flags to Watch For

1. Messy Site

A messy site suggests poor organization and lack of care.

Materials scattered, rubbish piling up, no safety measures - these are warnings.

2. Subcontractors Not Showing Up

If the site is often empty or subcontractors leave early, the build will drag on.

3. Rework

If you see the same thing being built, torn down, and rebuilt, it's a sign of poor planning or mistakes.

4. Builder Is Hard to Reach

If the builder doesn't return calls, dodges questions, or avoids site visits, something's wrong.

5. Shortcuts

Examples:

Skipping building wrap
Not installing flashings
Using cheaper materials than specified

If you see this, stop the build and get it fixed. Shortcuts cost you later.

What to Do If Something Goes Wrong

1. Document It

Take photos. Write down what you observed and when.

2. Tell the Builder Immediately

Don't wait. If something's wrong, raise it now (before it's covered up or built over).

3. Refer to the Contract and Plans

Is the issue a deviation from the contract or plans? If so, the builder must fix it.

4. Get a Second Opinion

If the builder says "it's fine" but you're not convinced, hire an independent building inspector ($300-$600) to assess it.

5. Escalate If Necessary

If the builder refuses to fix a legitimate issue, contact:

Registered Master Builders (if they're a member)
Building Disputes Tribunal
A construction lawyer

If you can tick every box, the build is complete.

Chapter 11: Site Visits & Communication

How often to visit, what to check, and how to maintain a good relationship with your builder without being a pain.

Why Site Visits Matter

Your builder is managing the project, but it's your house and your money.

Site visits help you:

Catch issues early (before they're expensive to fix)
Stay informed (no surprises)
Make decisions in real-time (e.g., "Does this layout feel right?")
Build trust with your builder (shows you're engaged, not absent)

But too many visits - or poorly timed ones - can annoy your builder and slow the build.

The key is balance.

How Often Should You Visit?

During Earthworks and Foundations (Weeks 1-4)

Visit: Once a week

Why: Critical stage. Foundation mistakes are expensive to fix.

What to check:

House is positioned correctly on the section
Foundation is square and level
Drainage slopes away from the house

During Framing (Weeks 5-8)

Visit: Once or twice a week

Why: This is when the layout becomes real. You'll see room sizes, ceiling heights, and flow.

What to check:

Room sizes feel right (not too small or large)
Windows are in the right location and size
Doors open the right way
Roof pitch looks correct

During Cladding and Pre-line (Weeks 9-16)

Visit: Once a week

Why: Weatherproofing and insulation are critical. Mistakes here cause long-term problems.

What to check:

Building wrap is intact (no tears or gaps)
Flashings installed around windows and doors
Insulation fills all cavities
Enough power points and lights in every room

During Fit-out (Weeks 17-24)

Visit: Once or twice a week

Why: Selections are being installed. You need to confirm they're correct.

What to check:

Kitchen is the right style and color
Tiles match what you approved
Flooring is the right type and color
Paint colors are correct

During Final Stage (Weeks 25-28)

Visit: As needed (maybe 2-3 times)

Why: Walk-throughs to check quality and identify defects.

What to check:

All fixtures work
No defects (scratches, dents, poor finishing)
Landscaping is complete (if in contract)

Best Practices for Site Visits

1. Visit at the Same Time Each Week

E.g., every Wednesday at 3 PM. This creates a routine and the builder knows to expect you.

2. Don't Turn Up Unannounced During Critical Work

If the builder is pouring concrete or installing trusses, stay away. You'll be in the way.

3. Bring a Notebook and Camera

Take photos of anything you want to discuss with the builder later.

Write down questions so you don't forget.

4. Don't Give Instructions to Subcontractors

If you see something wrong, tell the builder - not the plumber, electrician, or framer.

The builder is responsible for managing subcontractors. Going around them creates confusion and conflict.

5. Bring Your Partner (If Applicable)

If you're building with a partner, try to visit together. This prevents "I thought you said..." disagreements later.

6. Don't Bring an Entourage

Friends and family are excited to see the house, but a crowd on-site is disruptive.

Save the tours for after handover.

What to Look for During Site Visits

Foundations and Earthworks

House is positioned correctly (measure setbacks from boundaries)
Foundation is level (use a spirit level if you have one)
Drainage pipes are sloped correctly (water should flow away)
No large rocks or debris left under the slab

Framing

Walls are straight (sight down each wall - it should be straight, not bowed)
Roof is square and level
Windows are the right size and in the right location
Bracing is installed (diagonal braces or plywood panels)

Cladding and Weatherproofing

Building wrap is installed and intact (no tears)
Flashings installed above all windows and doors
Cladding is straight and evenly spaced
No gaps where water can enter

Plumbing, Electrical, Insulation

Insulation fills all cavities (no gaps, no compression)
Plumbing pipes are supported and won't rattle
Electrical cables are neat and safe
Enough power points in every room (kitchen: 4-6, living: 4-6, bedrooms: 2-4)

Fit-out

Kitchen cabinets are level and doors close properly
Tiles are straight and grout lines are even
Flooring is smooth (no gaps, bumps, or squeaks)
Paint is even (no drips, streaks, or missed spots)
Fixtures work (taps, lights, doors, windows)

Final

All defects from earlier visits are fixed
No damage to fixtures or finishes
Site is clean (no rubbish, tools, or materials left behind)

Communicating With Your Builder

1. Agree on a Communication Schedule

Weekly or fortnightly check-ins (phone, email, or in-person) keep everyone aligned.

2. Use Email for Important Decisions

Verbal agreements are forgotten. Email creates a record.

Example:
"Hi [Builder], I've approved the stone benchtop upgrade ($5,400). Please proceed. Thanks, [Your Name]"

3. Be Clear and Specific

Don't say "I'm not sure about the kitchen." Say "The kitchen cabinets are 50mm too high - can we adjust them?"

4. Ask Questions (Don't Assume)

If you don't understand something, ask. Builders would rather explain than fix a mistake later.

5. Be Respectful

Your builder is juggling multiple projects, subcontractors, suppliers, and council. They're busy.

A polite, patient approach gets better results than demands and complaints.

6. Respond Quickly to Decisions

If the builder asks "Which tile do you want?" respond within 24-48 hours.

Delays in decision-making delay the build.

Red Flags in Communication

1. Builder Avoids Your Calls or Emails

If the builder doesn't respond for days, something's wrong.

2. Builder Is Defensive or Dismissive

"Don't worry about it" or "It'll be fine" are not acceptable answers if you have a legitimate concern.

3. Builder Blames Everyone Else

"The council is slow." "The plumber didn't show up." "The supplier is out of stock."

Some delays are legitimate, but if every issue is someone else's fault, the builder isn't managing the project properly.

4. Builder Pressures You to Decide Quickly

"I need an answer today or we're delayed by a month."

Most decisions don't need to be made instantly. Take the time you need.

What to Do If Communication Breaks Down

1. Request a Formal Meeting

Sit down with the builder and address the issues. Bring a list of concerns.

2. Document Everything

Switch to email for all communication. Keep a record.

3. Involve a Mediator

If things are tense, bring in a third party (e.g., RMBA mediator, independent building consultant) to facilitate.

4. Escalate If Necessary

If the builder is unresponsive or uncooperative, contact:

Registered Master Builders (if they're a member)
Building Disputes Tribunal
A construction lawyer

Good communication = fewer surprises, fewer delays, and a better outcome.

Chapter 12: Insurance & Warranties

What coverage you need during and after the build, and how to protect yourself if something goes wrong.

Why Insurance Matters

Building a house is risky. Things can go wrong:

Fire or storm damages the half-built house
A subcontractor is injured on-site
The builder goes bankrupt mid-project
Defects appear years after handover

Without the right insurance and warranties, you're liable for these losses.

With the right coverage, you're protected.

Insurance During the Build

1. Contract Works Insurance

What it covers: Physical damage to the build (fire, storm, theft, vandalism, accidental damage)

Who should have it: The builder (usually), but confirm it in the contract.

Why it matters: If the half-built house burns down, contract works insurance pays to rebuild it. Without it, you're out of pocket.

What to check:

Builder has current contract works insurance
The policy covers the full contract value (not underinsured)
You're named as an interested party on the policy

Typical cost: Included in the builder's price (or $1,500-$3,000 if you arrange it yourself).

2. Public Liability Insurance

What it covers: Injury or property damage to third parties (e.g., a subcontractor falls off scaffolding, or the build damages a neighbor's fence)

Who should have it: The builder.

Why it matters: If someone is injured on-site and sues, public liability insurance covers legal costs and compensation.

What to check:

Builder has current public liability insurance (minimum $2 million cover)
You request a copy of the certificate of currency

3. Your Existing Home and Contents Insurance (If Applicable)

If you're building on the same section where you currently live, notify your home insurer.

Why? Because the build increases risk (tools, materials, workers on-site). Your existing policy might not cover damage related to the build.

4. Life and Income Protection (Optional)

If you're the main income earner and something happens to you mid-build, how will the project be completed?

Life insurance and income protection ensure your family can finish the build even if you can't work.

Insurance After Handover

Once the build is complete and you move in, you need standard home and contents insurance.

What to Insure For

Replacement value: The cost to rebuild the house if it's destroyed (not market value)
Contents: Furniture, appliances, personal items
Liability: If someone is injured on your property

Typical Cost

Home insurance: $1,200-$2,500/year (depending on location, size, and risk factors)
Contents insurance: $300-$800/year

How to Get the Best Rate

Get quotes from 3-5 insurers
Bundle home and contents with the same insurer (often discounts)
Increase your excess (e.g., $1,000 instead of $500) to lower the premium
Install smoke alarms, security systems (some insurers offer discounts)

Warranties You Should Have

1. Statutory Warranties (Building Act 2004)

All builders in New Zealand must provide statutory warranties under the Building Act:

What's covered:

Work done with reasonable care and skill
Materials suitable for the purpose
Work complies with the Building Code
Work will be completed (if contracted)

How long: Varies by defect type:

Major defects (structural, weathertightness): 10 years
Minor defects: 1 year

The catch: You have to prove the builder breached their duty. This can be difficult and expensive (requires legal action).

2. Master Build 10-Year Guarantee (RMBA Members)

If your builder is a Registered Master Builders member, they should offer the Master Build 10-Year Guarantee.

What's covered:

Major defects (structural, weathertightness)
Builder's insolvency (someone else finishes the build)

How long: 10 years from handover

Cost: Included if your builder is an RMBA member (but confirm it in the contract)

Why it's better than statutory warranties: If the builder goes bust or refuses to fix defects, the RMBA steps in and arranges remediation (up to policy limits).

3. Manufacturer Warranties

Many products come with their own warranties:

Roofing (e.g., Colorsteel: 15-30 years)
Windows (e.g., double glazing: 5-10 years)
Cladding (e.g., James Hardie: 15-25 years)
Appliances (e.g., oven, dishwasher: 1-5 years)

What to do:

Collect all warranties and store them safely
Register products where required (some warranties are void if you don't register)
Keep receipts and invoices (proof of purchase)

What to Do If Your Builder Goes Bust Mid-Project

This is rare, but it happens. If your builder goes into liquidation before the house is finished:

1. Check Contract Works Insurance

If the builder had contract works insurance, it should cover the cost to finish the build (up to policy limits).

2. Check the Master Build Guarantee

If your builder was an RMBA member, the guarantee covers completion (up to policy limits).

3. Contact Your Bank

Your bank has a vested interest in the build being completed. They may:

Release additional funds to hire a new builder
Renegotiate the loan terms
Provide a bridging loan

4. Hire a New Builder

Get quotes from other builders to complete the work.

Expect to pay more (new builders charge a premium for taking over someone else's project).

5. Seek Legal Advice

A construction lawyer can help you:

Recover deposits or payments from the liquidated builder
Negotiate with subcontractors (who may be owed money for work already done on the property)
Navigate insurance claims

What to Do If There Are Defects After Handover

Defects are issues that don't comply with the Building Code or the building contract.

Common defects:

Leaks (roof, windows, cladding)
Cracks (walls, foundations)
Poor finishes (uneven tiles, paint defects)
Non-functional systems (plumbing, electrical)

Step 1: Document the Defect

Take photos and notes. Record when you first noticed it.

Step 2: Notify the Builder in Writing

Send an email or letter describing the defect and requesting it be fixed.

Include a reasonable timeframe (e.g., "Please inspect and advise within 14 days").

Step 3: Builder Inspects and Agrees to Fix

Most builders will fix defects within the first 12 months (especially if they want a good reputation).

Step 4: If Builder Refuses or Delays

Check the warranty: Is it covered by statutory warranties or the Master Build Guarantee?
Get an independent assessment: Hire a building inspector ($500-$1,000) to confirm it's a defect.
Escalate: Contact RMBA (if applicable) or the Building Disputes Tribunal.

Step 5: Legal Action (Last Resort)

If the builder refuses to fix a legitimate defect, you may need to:

File a claim with the Disputes Tribunal (for claims under $30,000)
Hire a lawyer and take the builder to court (for claims over $30,000)

This is expensive and slow, so try to resolve it directly first.

The Insurance and Warranty Checklist

Before the build starts:

Confirm builder has contract works insurance
Confirm builder has public liability insurance ($2M+ cover)
Request copies of insurance certificates
Check if builder offers Master Build 10-Year Guarantee
Notify your existing home insurer (if building on same property)

During the build:

Ensure insurance remains current (check periodically)
Collect all product warranties and receipts

After handover:

Arrange home and contents insurance before moving in
Register product warranties where required
Store all warranties, receipts, and building documents safely
Understand your rights under statutory warranties and Master Build Guarantee

If something goes wrong:

Document the issue (photos, notes)
Notify the builder in writing
Get an independent assessment if needed
Escalate to RMBA or Disputes Tribunal if builder doesn't respond

Insurance and warranties are your safety net. Make sure you have them.

Chapter 13: Landscaping & Exteriors

How to plan landscaping, driveways, and fencing without blowing the budget - and what to do yourself vs. hire out.

Why Landscaping Gets Neglected (and Why That's a Mistake)

Most first-time builders spend 12 months obsessing over the house - and then realize they have no budget left for landscaping.

The result?

A beautiful house surrounded by mud and weeds
No driveway (so you park on the grass and create ruts)
No fence (so the dog escapes and neighbors complain)
No outdoor living space (so you can't enjoy the section)

Landscaping isn't optional. It's part of the build.

Budget for it from day one.

What's Included in "Landscaping and Exteriors"?

1. Driveway

Material (concrete, asphalt, metal/gravel)
Length and width
Drainage and crossings

2. Fencing

Boundary fences (front, sides, back)
Material (timber, Colorbond, wire)
Height and style

3. Retaining Walls

If the section is sloped or needs leveling
Material (timber sleepers, concrete blocks, stone)

4. Paths and Paving

Path from driveway to front door
Patio or deck
Paths to garage, letterbox, bins

5. Lawn and Planting

Topsoil (spread and leveled)
Grass (seed or turf)
Garden beds and planting
Mulch

6. Irrigation

Sprinkler system or drip irrigation (optional but useful in dry areas)

7. Outdoor Features

Deck or patio
Letterbox
Clothesline
Outdoor lighting
Garden shed

How Much Does Landscaping Cost?

Item	Typical Cost (NZD)
Driveway (concrete, 30m x 3m)	$12,000-$18,000
Driveway (metal/gravel, 30m x 3m)	$3,000-$6,000
Boundary fencing (timber, 40m)	$8,000-$12,000
Boundary fencing (Colorbond, 40m)	$12,000-$18,000
Retaining wall (timber sleepers, 10m)	$5,000-$10,000
Retaining wall (concrete blocks, 10m)	$8,000-$15,000
Lawn (topsoil, turf, 300m²)	$5,000-$8,000
Garden beds and planting (basic)	$3,000-$6,000
Deck (20m²)	$8,000-$15,000
Letterbox	$200-$800
Clothesline	$150-$500
Outdoor lighting (basic)	$1,500-$4,000

Total for basic landscaping (driveway, fencing, lawn, paths): $30,000-$60,000

Most first-time builders underestimate this by half.

What to Prioritize (If Budget Is Tight)

Must-Haves (Do First)

Driveway: You need somewhere to park.
Front path: You need a way to get from the driveway to the front door without walking through mud.
Basic lawn: Topsoil and grass seed (cheaper than turf) to stabilize the ground.
Boundary fence (if required by covenant or for privacy/security).

Nice-to-Haves (Do Later If Budget Allows)

Deck or patio
Garden beds and planting
Irrigation system
Outdoor lighting
Feature landscaping (stones, water features, etc.)

Can Wait (Do Over Time)

Advanced planting (trees, hedges)
Garden shed
Full irrigation
Decorative features

Start with the must-haves. You can always add more later.

Driveway: Concrete vs. Metal/Gravel

Concrete

Pros:

Durable (lasts 30+ years)
Looks professional
Low maintenance

Cons:

Expensive ($12,000-$18,000 for a typical driveway)
Cracks over time (especially if ground settles)

Best for: Permanent, high-quality finish.

Metal/Gravel

Pros:

Cheap ($3,000-$6,000)
Quick to install
Easy to repair

Cons:

Needs topping up every 2-3 years
Can wash away in heavy rain
Looks less polished

Best for: Tight budgets or temporary driveways.

Asphalt (Middle Ground)

Cost: $8,000-$12,000
Pros: Cheaper than concrete, more durable than metal
Cons: Needs resealing every 5-10 years

Best for: Suburban homes where appearance matters but budget is tight.

Fencing: What's Required and What's Optional

Legal Requirements

In New Zealand, you're generally required to contribute to a boundary fence if your neighbor requests it (Fencing Act 1978).

Cost is split 50/50 with the neighbor (unless you agree otherwise).

What counts as "adequate":

Post and wire (cheapest)
Timber palings (mid-range)
Colorbond (most expensive)

Your neighbor can request a fence, but you can negotiate the type.

Front Fence (Optional)

Most subdivisions don't require a front fence, but you might want one for:

Privacy
Security
Aesthetic (defines the property boundary)

Cost: $2,000-$6,000 (depending on length and material)

What Type of Fence?

Type	Cost per Meter	Pros	Cons
Post and wire	$50-$80	Cheap, functional	Not private, not decorative
Timber paling (1.8m)	$150-$250	Private, classic look	Requires maintenance (staining/painting)
Colorbond (1.8m)	$200-$350	Durable, low maintenance, modern	Expensive

Recommendation: Colorbond for boundaries (long-term value), timber for front (aesthetic).

Retaining Walls: When You Need Them

If your section is sloped or you've created a flat building platform, you'll need retaining walls to hold back the earth.

Types:

1. Timber Sleepers

Cost: $500-$1,000 per linear meter (depending on height)
Pros: Cheaper, DIY-friendly
Cons: Rots over time (15-25 years)

2. Concrete Blocks (e.g., Keystone, Versalok)

Cost: $800-$1,500 per linear meter
Pros: Durable, modular, DIY-possible
Cons: More expensive

3. Poured Concrete

Cost: $1,000-$2,000+ per linear meter
Pros: Permanent, strong
Cons: Expensive, requires engineering

For walls over 1.5m high, get a structural engineer to design it (and get building consent).

Lawn: Seed vs. Turf

Grass Seed

Cost: $1,000-$2,000 (for 300m²)
Pros: Cheap
Cons: Takes 3-6 months to establish, needs watering and care

Best for: Tight budgets, patient builders.

Turf (Instant Lawn)

Cost: $4,000-$7,000 (for 300m²)
Pros: Instant result, looks great immediately
Cons: Expensive

Best for: Builders who want to move in and have it look finished.

Preparation (Critical)

Regardless of seed or turf:

Spread topsoil (minimum 100mm depth)
Level the ground (remove rocks, compact lightly)
Fertilize (pre-seed or pre-turf fertilizer)

Poor preparation = patchy, weedy lawn.

What to DIY vs. Hire Out

DIY-Friendly (If You're Handy)

Grass seeding
Garden bed planting
Mulching
Painting fences
Installing a clothesline or letterbox
Basic garden edging

Hire a Professional

Concrete driveway (requires skill and equipment)
Retaining walls over 1m high (engineering required)
Turf installation (heavy, needs to be laid quickly)
Large-scale earthworks
Irrigation systems (plumbing knowledge required)

DIY saves money, but only if you have the skills and time. Don't DIY something critical (like a retaining wall) and have it fail a year later.

Staging Landscaping (If Budget Is Tight)

You don't have to do everything at once.

Year 1: Must-Haves

Driveway
Front path
Boundary fence
Basic lawn (seed or cheap turf)

Year 2: Nice-to-Haves

Deck or patio
Garden beds and planting
Upgrade lawn (overseed, fertilize)

Year 3+: Upgrades

Advanced planting (trees, hedges)
Irrigation
Outdoor lighting
Feature landscaping

This spreads the cost over 2-3 years instead of hitting you all at once.

The Landscaping Budget Checklist

Before the build starts:

Budget for landscaping (don't leave it until the end)
Decide: basic, mid-range, or high-spec landscaping?
Get 3 quotes for driveway, fencing, and major landscaping

During the build:

Save topsoil from excavation (reuse for lawn and garden beds)
Protect areas you want to landscape (don't let builders dump rubbish there)

After the build:

Prioritize: driveway, path, lawn, fence
DIY what you can (planting, seeding, small projects)
Hire professionals for critical work (concrete, retaining, turf)
Stage work over 1-3 years if budget is tight

Landscaping completes the home. Don't skip it.

Chapter 14: Pre-Handover Inspection

The final walk-through checklist - what to check, how to identify defects, and what to demand before you accept the house.

Why the Pre-Handover Inspection Matters

The pre-handover inspection is your last chance to identify issues before you take ownership.

Once you sign the handover documents and the builder leaves, fixing defects becomes much harder:

The builder is on to the next project (you're no longer a priority)
You're living in the house (harder to access areas for repairs)
The final payment has been made (builder has less incentive to return)

A thorough inspection now saves months of frustration later.

When Does the Pre-Handover Inspection Happen?

Timing: 1-2 weeks before the official handover date.

Who attends:

You (and your partner, if applicable)
The builder (or site manager)
Optionally: An independent building inspector (recommended)

How long: 2-4 hours (for a thorough inspection of a typical 150-200m² house)

Should You Hire an Independent Building Inspector?

Cost: $500-$1,000

What they do:

Inspect the house with you
Identify defects, code compliance issues, and poor workmanship
Provide a written report with photos

Is it worth it?

Yes, if:

You're not confident spotting defects yourself
The build has been problematic
You want an expert opinion before signing off

No, if:

The build has been smooth and the builder is reputable
You're comfortable doing the inspection yourself

Recommendation: If you can afford it, hire an inspector. They'll spot things you'd miss.

How to Document Defects

For every defect:

Take a photo (close-up and wide-angle for context)
Write a description (e.g., "Crack in plasterboard, master bedroom, north wall, 30cm from ceiling")
Mark the location (use masking tape or sticky notes so the builder can find it easily)

At the end of the inspection, compile a defects list (also called a snag list) and send it to the builder.

What Counts as a Defect?

Major Defects (Must Be Fixed Before Handover)

Leaks (roof, windows, plumbing)
Non-functional systems (plumbing, electrical, heating)
Structural issues (cracks, sagging, settlement)
Code violations (spotted by council or inspector)
Safety hazards (exposed wiring, unstable fixtures)

Minor Defects (Should Be Fixed Before Handover, But Negotiable)

Paint touch-ups
Small scratches or dents
Squeaky doors or floors
Uneven grout lines
Minor gaps or misalignments

Cosmetic Issues (Nice to Fix, But Not Critical)

Paint color slightly off
Minor blemishes in finishes
Small chips in tiles (if not in high-visibility areas)

Your goal: Get all major defects and most minor defects fixed before handover.

What Happens After the Inspection?

1. Builder Reviews the Defects List

The builder will review your list and either:

Agree to fix everything
Dispute some items (claim they're not defects)
Negotiate (fix some now, others later)

2. Builder Fixes the Defects

Allow 1-2 weeks for the builder to fix the defects.

3. Re-Inspection

Once the builder says the defects are fixed, do another walk-through to confirm.

If new issues have appeared or defects weren't fixed properly, add them to the list.

4. Sign Off on Handover

Once you're satisfied, you sign the handover documents and the house is officially yours.

What If the Builder Refuses to Fix Defects?

If the builder says "It's not a defect" or "It's good enough," you have options:

1. Refer to the Contract and Building Code

If the issue violates the contract or Building Code, the builder must fix it.

2. Get a Second Opinion

Hire an independent inspector to confirm whether it's a defect.

3. Withhold Final Payment

Most contracts allow you to withhold 5-10% of the final payment until defects are fixed.

Don't hand over the final payment until you're satisfied.

4. Escalate

Contact:

Registered Master Builders (if the builder is a member)
Building Disputes Tribunal
A construction lawyer

The Handover Documents You Should Receive

At handover, the builder should provide:

Code Compliance Certificate (CCC)
Copies of all building consent documentation
Copies of all council inspection records
Producer statements (from engineers, plumbers, electricians)
Product warranties (roof, windows, cladding, appliances)
Maintenance instructions (for heat pump, appliances, systems)
As-built plans (showing any changes from the original consent plans)
Keys (house, garage, windows)

Don't sign the handover until you've received all of these.

The Pre-Handover Checklist

Before the inspection:

Schedule the inspection 1-2 weeks before handover
Consider hiring an independent building inspector
Bring: camera, notepad, pen, flashlight, marble (for testing floors)

During the inspection:

Walk through every room, inside and out
Test everything (taps, lights, doors, windows, appliances)
Take photos of every defect
Compile a written defects list

After the inspection:

Send the defects list to the builder (email for record-keeping)
Allow 1-2 weeks for repairs
Do a re-inspection to confirm repairs
Withhold final payment until defects are fixed
Collect all handover documents
Sign handover documents only when satisfied

A thorough pre-handover inspection protects you. Don't skip it.

Chapter 15: Defects & Remediation

Your rights, the process for getting defects fixed, and what to do if the builder won't cooperate.

What Is a Defect?

A defect is any aspect of the build that doesn't meet:

The Building Code
The building consent plans
The building contract specifications
Reasonable standards of workmanship

Common defects:

Leaks (roof, windows, plumbing)
Cracks (foundations, walls, ceilings)
Poor finishes (uneven paint, tiles, flooring)
Non-functional systems (plumbing, electrical, heating)
Structural issues (sagging, settlement, poor bracing)

Defects can appear immediately or years after handover.

Your Rights Under NZ Law

1. Statutory Warranties (Building Act 2004)

All builders must provide statutory warranties:

Work done with reasonable care and skill
Materials are suitable for the purpose
Work complies with the Building Code
Work will be completed (if contracted)

Timeframes:

Major defects (structural, weathertightness): 10 years
Minor defects: 1 year

The catch: You must prove the builder breached their duty. This can require legal action.

2. Master Build 10-Year Guarantee (RMBA Members)

If your builder is a Registered Master Builders member, you should have the Master Build 10-Year Guarantee.

What's covered:

Major defects (structural, weathertightness)
Builder's insolvency (RMBA arranges completion or remediation)

Timeframes: 10 years from handover

How to claim: Contact the RMBA, provide evidence of the defect, and they'll assess and facilitate remediation.

3. Consumer Guarantees Act (if applicable)

If you're a consumer (not a business), goods and services must be:

Fit for purpose
Of acceptable quality
Match the description

This applies to building work, too. If the build doesn't meet these standards, you can claim under the CGA.

When to Report Defects

Immediate (Within Days of Discovery)

Leaks (roof, windows, plumbing)
Safety hazards (electrical faults, structural instability)
Non-functional systems (heating, plumbing, electrical)

Soon (Within Weeks)

Poor finishes (paint, tiles, flooring)
Minor cracks or gaps
Squeaky floors or doors

Monitor (Over Months/Years)

Foundation settlement (cracks appearing gradually)
Weathertightness issues (dampness, mold)
Long-term material failures (cladding, roofing)

Rule: Report defects as soon as you discover them. Delays can void warranties or make it harder to prove causation.

How to Report Defects

Step 1: Document the Defect

Take photos (close-up and wide-angle for context)
Write a description (location, size, severity)
Note when you first discovered it

Step 2: Notify the Builder in Writing

Send an email or letter:

Example:

Subject: Defect Notification – [Address]

Hi [Builder],

I've discovered a defect at the above property:

Description: Water leak around the north-facing bedroom window during heavy rain.

Location: Master bedroom, north wall.

First noticed: [Date]

Please inspect and advise on remediation within 14 days.

Photos attached.

Regards,
[Your Name]

Why email? It creates a written record with a timestamp.

Step 3: Builder Inspects

The builder (or a representative) should inspect the defect within 1-2 weeks.

Step 4: Builder Agrees to Fix (or Disputes)

If the builder agrees:

They'll provide a timeframe for remediation (e.g., "We'll fix it within 4 weeks")
They'll schedule the repair

If the builder disputes:

They might claim it's not a defect (e.g., "That's normal settlement")
They might claim it's not their responsibility (e.g., "You caused that damage")

Step 5: Repair Is Completed

Once repaired, inspect the work to confirm it's fixed properly.

Step 6: If Builder Refuses or Delays

Escalate (see below).

What If the Builder Won't Fix the Defect?

Option 1: Get an Independent Assessment

Hire an independent building inspector or engineer to assess the defect and provide a written report.

Cost: $500-$1,500
Why: An independent expert opinion strengthens your case if you need to escalate.

Option 2: Contact the RMBA (If Applicable)

If your builder is a Registered Master Builders member, contact the RMBA.

What they'll do:

Review your claim
Mediate between you and the builder
Arrange remediation (if covered by the Master Build Guarantee)

Contact: masterbuilder.org.nz

Option 3: Ministry of Business, Innovation and Employment (MBIE)

MBIE provides free guidance on building disputes and your rights.

Contact: building.govt.nz

Option 4: Building Disputes Tribunal

For disputes under $30,000, you can file a claim with the Disputes Tribunal.

What they do:

Hear both sides
Make a binding decision (no lawyers required)

Cost: $45-$200 filing fee

Timeframe: 2-6 months

Website: disputestribunal.govt.nz

Option 5: Weathertight Homes Tribunal (For Weathertightness Claims)

If the defect is weathertightness-related (leaks, dampness), you can file a claim with the Weathertight Homes Tribunal.

What's covered: Defects causing water penetration
Timeframe: Claims must be filed within 10 years of the defect first appearing
Website: justice.govt.nz

Option 6: Legal Action (Last Resort)

For claims over $30,000 or complex disputes, hire a construction lawyer and take the builder to court.

Cost: $10,000-$50,000+ (depending on complexity)
Timeframe: 6 months to 2+ years

Only pursue this if:

The defect is severe and expensive to fix
The builder refuses to cooperate
Other options have failed

Common Defects and How They're Fixed

Defect	Cause	Remediation
Roof leak	Poor flashing, damaged roofing	Re-flash, replace damaged roofing
Window leak	Poor installation, no flashing	Re-install window, add flashing
Foundation cracks	Settlement, poor compaction	Monitor (minor), underpin or repair (major)
Wall cracks	Settlement, poor framing	Fill and repaint (minor), re-frame (major)
Poor paint finish	Inadequate prep, cheap paint	Sand and repaint
Uneven tiles	Poor installation	Re-lay affected tiles
Plumbing leak	Loose fitting, poor installation	Tighten or replace fittings
Electrical fault	Incorrect wiring	Re-wire

How Long Do Repairs Take?

Defect Type	Typical Repair Time
Plumbing leak (minor)	1-2 days
Paint touch-ups	1-3 days
Roof leak (minor)	3-5 days
Window re-installation	1-2 weeks
Major structural repair	4-12 weeks

What If the Builder Has Gone Out of Business?

If the builder is no longer operating:

1. Check the Master Build Guarantee

If your builder was an RMBA member, the guarantee still applies. Contact the RMBA to arrange remediation.

2. Check Insurance

If you or the builder had contract works insurance or defects liability insurance, it may cover the repair.

3. Hire Another Builder

Get quotes from other builders to fix the defect.

Expect to pay more (remediation is often more expensive than the original work).

4. Seek Legal Advice

A construction lawyer can help you:

Pursue the builder's directors (if the company was liquidated to avoid liability)
Claim against subcontractors or suppliers (if they're liable)
Navigate insurance claims

Preventing Defects in the First Place

The best way to deal with defects is to prevent them:

1. Choose a Reputable Builder

Vet them thoroughly (Chapter 5). Check references, licenses, insurance.

2. Visit the Site Regularly

Catch issues early, before they're covered up.

3. Attend Council Inspections

Make sure the build passes every inspection.

4. Do a Thorough Pre-Handover Inspection

Identify defects before you take ownership (Chapter 14).

5. Don't Pay the Final Payment Until Defects Are Fixed

Withhold 5-10% until you're satisfied.

The Defects Remediation Checklist

When you discover a defect:

Document it (photos, description, date)
Notify the builder in writing (email)
Request an inspection within 14 days
Get an independent assessment (if disputed)
Track the builder's response and actions

If the builder won't cooperate:

Contact the RMBA (if applicable)
File a claim with the Disputes Tribunal (if under $30,000)
Contact MBIE for guidance
Hire a lawyer (if over $30,000 or complex)

Don't ignore defects. They rarely fix themselves, and delays can void your rights.

Chapter 16: Moving In

The practical checklist for move day - what to do, what to bring, and how to make the transition smooth.

Moving Day Is the Reward

After 12-18 months of planning, building, and stressing, you're finally moving into your new home.

This chapter is about making move day as smooth as possible - so you can focus on celebrating, not scrambling.

Before Move Day

2 Weeks Before

Book a moving company (or arrange a truck and helpers)
Order packing boxes and materials
Start packing non-essentials (books, decorations, off-season clothes)
Notify utilities (power, internet, gas) of your move-in date
Update your address with:
- Bank
- Insurance (home, car, health)

Chapter 17: Post-Build Maintenance

How to protect your investment - ongoing maintenance tasks, seasonal checklists, and what to watch for.

Why Maintenance Matters

Your new home is a $500,000-$900,000 investment. Proper maintenance protects that investment by:

Preventing small issues from becoming big (and expensive) problems
Extending the life of materials and systems
Maintaining the home's value
Keeping your family safe and comfortable

Neglect maintenance, and you'll pay for it later - in repairs, replacement costs, and stress.

The First Year: Monitor Everything

The first 12 months are critical. This is when:

Settlement occurs (minor cracks are normal, major cracks are not)
Systems are tested (heating, plumbing, electrical)
Materials adjust to the climate (timber expands/contracts, paint cures)

What to do:

Keep a logbook of any issues (cracks, leaks, squeaks, etc.)
Report defects to the builder immediately (most warranties cover the first year)
Take photos every 3 months (for insurance and future reference)

Seasonal Maintenance Checklist

Spring (September - November)

Exterior

Clean gutters and downpipes (remove leaves and debris)
Check roof for damage (missing/loose tiles, rusted Colorsteel)
Inspect cladding for cracks, gaps, or damage
Check window and door seals (replace if cracked or missing)
Wash windows (inside and out)
Pressure-wash paths, driveway, and deck

Interior

Test smoke alarms (replace batteries if needed)
Clean or replace rangehood filters
Vacuum heat pump filters
Deep clean (dust, vacuum, mop)

Garden

Fertilize lawn
Prune trees and shrubs
Mulch garden beds
Check irrigation system (if installed)

Summer (December - February)

Exterior

Inspect deck for splinters, rot, or loose boards
Re-oil or stain deck (if timber)
Check fences for damage or rot
Water lawn and garden (if dry)

Interior

Test heat pump (cooling mode)
Clean windows and screens
Check for pests (ants, wasps, rodents)

Garden

Water regularly (especially new plants)
Mow lawn weekly
Weed garden beds

Autumn (March - May)

Exterior

Clean gutters and downpipes (remove autumn leaves)
Check roof for damage (before winter storms)
Inspect cladding and flashings
Seal any cracks in driveway or paths

Interior

Test heat pump (heating mode)
Check for drafts (windows, doors, vents)
Bleed radiators (if you have a hydronic heating system)

Garden

Rake leaves
Plant winter vegetables or cover crops
Mulch garden beds (protects roots in winter)

Winter (June - August)

Exterior

Check for leaks (roof, windows, doors) during heavy rain
Clear drains and stormwater grates
Inspect gutters (ensure they're not overflowing)

Interior

Run heat pump or heating system regularly (prevents moisture buildup)
Ventilate (open windows for 10-15 minutes daily, even in winter)
Check for dampness or mold (especially in bathrooms, laundry, wardrobes)
Test smoke alarms

Garden

Prune deciduous trees (while dormant)
Protect frost-sensitive plants
Stay off wet grass (compacts soil)

Annual Maintenance Tasks

Once a year (pick a season and stick to it):

Professional gutter clean (if you can't do it safely yourself)
Professional heat pump service (clean coils, check refrigerant)
Roof inspection (hire a professional if you can't safely access the roof)
Repaint or re-stain exterior timber (if needed)
Reseal bathroom and kitchen (silicone around sinks, showers, baths)
Test and service hot water cylinder (check anode, flush sediment)
Inspect and service garage door and opener
Update home inventory (for insurance purposes)

What to Watch For (Early Warning Signs)

Exterior

Issue	Early Warning Sign	What to Do
Roof leak	Water stains on ceiling, damp insulation	Inspect roof, re-flash or repair
Cladding failure	Cracks, gaps, peeling paint	Re-seal, re-paint, or replace
Gutter overflow	Water pouring over gutters during rain	Clean gutters, check downpipes
Foundation settlement	Cracks in walls or floors (especially diagonal)	Monitor; if growing, get a structural engineer
Window leaks	Water stains around windows, dampness	Re-seal, check flashings

Interior

Issue	Early Warning Sign	What to Do
Plumbing leak	Damp patches, dripping taps, low water pressure	Tighten fittings, replace washers, call a plumber
Electrical fault	Flickering lights, tripping breakers, burning smell	Call an electrician immediately
Mold/dampness	Musty smell, black spots on walls/ceilings	Improve ventilation, fix leaks, clean mold
Pest infestation	Droppings, gnaw marks, nests	Set traps, seal entry points, call pest control

Ventilation: The Most Overlooked Maintenance Task

New homes are well-insulated and airtight. That's great for energy efficiency - but bad for moisture buildup.

Without proper ventilation, you'll get:

Condensation on windows
Mold in bathrooms, wardrobes, and corners
Musty smells
Damage to timber and plasterboard

How to ventilate:

Open windows for 10-15 minutes every morning (even in winter)
Run exhaust fans during and after showers (for 15-20 minutes)
Use the rangehood when cooking
Keep wardrobes and cupboards slightly open (allows air circulation)
Don't dry laundry indoors (use a dryer or outdoor line)

Cost of poor ventilation: $5,000-$20,000+ in mold remediation and repairs.

When to DIY vs. Hire a Professional

DIY-Friendly

Cleaning gutters (if single-story and safe)
Washing windows
Replacing air filters (heat pump, rangehood)
Testing smoke alarms
Touching up paint
Weeding and lawn care
Sealing small cracks (silicone, caulk)

Hire a Professional

Roof repairs (dangerous and requires skill)
Electrical work (illegal to DIY in NZ unless you're a licensed electrician)
Plumbing (except minor tasks like replacing washers)
Heat pump servicing (requires specialized equipment)
Structural repairs (cracks, settlement)
Mold remediation (if extensive)

Rule: If it's dangerous, requires a license, or you're not confident, hire a pro.

Maintenance Costs (Annual Budget)

Task	Frequency	Cost (NZD)
Gutter cleaning	Twice a year	$200-$400
Heat pump service	Once a year	$150-$250
Roof inspection	Once a year	$200-$400
Exterior painting/staining	Every 5-10 years	$5,000-$15,000
Deck re-oiling	Every 1-2 years	$500-$1,500
Plumbing maintenance	As needed	$150-$500
Electrical maintenance	As needed	$150-$500
Pest control	As needed	$150-$400
Total Annual Budget		$1,000-$3,000

Budget $1,500-$2,000/year for routine maintenance. Some years you'll spend less, others more (e.g., if you repaint).

The Maintenance Logbook

Keep a logbook (digital or physical) to track:

Maintenance tasks completed (date, cost, contractor)
Defects discovered (date, description, resolution)
Warranty information (products, expiry dates)
Manuals and instructions (heat pump, appliances, systems)

Why? It helps you:

Remember when tasks were last done
Provide records to buyers (if you sell)
Claim insurance (if needed)

Long-Term Replacement Costs (What to Budget For)

Item	Expected Lifespan	Replacement Cost (NZD)
Roof (Colorsteel)	30-50 years	$15,000-$30,000
Roof (tiles)	50+ years	$20,000-$40,000
Heat pump	10-15 years	$3,000-$6,000
Hot water cylinder	10-15 years	$1,500-$3,000
Carpet	10-15 years	$5,000-$10,000
Paint (exterior)	10-15 years	$8,000-$20,000
Kitchen	15-25 years	$20,000-$50,000
Bathroom	15-25 years	$10,000-$25,000

Plan ahead: Set aside $2,000-$5,000/year in a maintenance fund for future replacements.

The Post-Build Maintenance Checklist

First year:

Monitor for settlement (cracks, movement)
Report defects to builder immediately
Test all systems regularly

Seasonally:

Spring: Clean gutters, test systems, fertilize lawn
Summer: Check deck, water garden, test cooling
Autumn: Clean gutters, check roof, test heating
Winter: Check for leaks, ventilate, prevent mold

Annually:

Professional gutter clean
Heat pump service
Roof inspection
Reseal bathrooms and kitchen
Update home inventory

Every 5-10 years:

Repaint or re-stain exterior
Re-oil deck
Replace worn carpets or flooring

Maintenance isn't glamorous, but it protects your investment.

Chapter 18: Building as an Investment

Equity, valuations, future-proofing, and how your new build affects your financial position.

Your New Build Is More Than a Home - It's an Asset

When you build a new home, you're not just creating a place to live. You're also:

Building equity (the difference between what you owe and what the home is worth)
Creating an asset that can appreciate over time
Potentially setting yourself up for future investment opportunities

Understanding the financial side helps you make smarter decisions - now and in the future.

How Much Equity Do You Have?

Equity = Home Value - Mortgage Balance

Example:

You built a home for $600,000 (land + build)
You borrowed $480,000 (80% LVR)
You contributed $120,000 cash (20% deposit)
The home is valued at $650,000 (appreciated slightly since completion)

Your equity:
$650,000 (value) - $480,000 (mortgage) = $170,000 equity

That's $120,000 from your deposit + $50,000 from appreciation.

Does a New Build Appreciate Immediately?

Sometimes, but not always.

Factors That Increase Value

You bought the section well (below market value or in a growth area)
The build cost was below market value (e.g., you built for $500k, but similar homes sell for $600k)
The area has appreciated during the build (prices rose 5-10% over 12 months)

Factors That Decrease Value (or Limit Appreciation)

You over-capitalized (spent $700k building in an area where homes sell for $650k)
The area is slow or declining
The build took longer than expected (market softened during delays)

Reality check: Don't assume instant equity. Get a valuation 6-12 months after completion to know your real position.

Should You Get a Valuation After Completion?

Yes, if:

You want to know your true equity position
You're considering refinancing or accessing equity
You're thinking of selling in the next 2-5 years

Cost: $600-$1,200 for a registered valuation

Timing: Wait 6-12 months after completion (gives the market time to stabilize).

Using Equity for Future Investments

If your home has appreciated and you've built equity, you can:

1. Refinance and Access Equity

Borrow against your home's increased value (without selling).

Example:

Home is now worth $700,000
You owe $480,000
Equity is $220,000
Bank will lend up to 80% LVR = $560,000
You can access $80,000 in equity ($560k - $480k)

What to use it for:

Deposit on an investment property
Home improvements (deck, landscaping)
Debt consolidation

Risk: You're increasing your debt. Make sure the investment generates a return (e.g., rental income).

2. Sell and Upgrade

If your home has appreciated significantly, you can sell and use the equity as a deposit on a larger or better-located home.

Example:

Sell for $700,000
Pay off $480,000 mortgage
Walk away with $220,000 (minus selling costs)
Use $150,000 as a deposit on a $900,000 home

3. Rent It Out and Buy Another Home

Keep your current home as an investment property (rent it out) and use the equity to buy another home to live in.

This requires:

Sufficient income to service two mortgages
A property that generates positive or neutral cash flow (rent covers most of the mortgage)
Understanding of landlord responsibilities

Talk to a mortgage broker before pursuing this.

Future-Proofing Your Home

Future-proofing means designing and building your home so it remains functional, desirable, and valuable for decades.

Design for Flexibility

Open-plan living (can be adapted as needs change)
Extra bedroom (can be an office, guest room, or nursery)
Accessible bathroom on the ground floor (useful if someone becomes mobility-impaired)

Build Above Minimum Standards

Double glazing (energy efficiency, comfort, resale value)
Insulation above code (R2.8 walls, R3.6 ceiling)
Quality fixtures and fittings (last longer, look better)

Consider Sustainability

Buyers increasingly value:

Energy efficiency (heat pump, solar panels, LED lighting)
Water efficiency (low-flow fixtures, rainwater tanks)
Sustainable materials (FSC timber, low-VOC paint)

Cost: 5-10% more upfront
Return: Higher resale value, lower operating costs, future-proofed against rising energy prices

Plan for Multi-Generational Living

As NZ's population ages, multi-generational homes are more common:

Granny flat or self-contained unit
Ground-floor bedroom and bathroom (for elderly parents)
Separate entrance (for adult children or tenants)

This adds value and flexibility.

Tax Implications (What You Need to Know)

Bright-Line Test

If you sell your home within 2 years of buying it, you may have to pay tax on any profit (unless it's your main home and you've lived there continuously).

How to avoid: Live in the home for at least 2 years before selling.

Renting Out Your Home

If you rent out your home, rental income is taxable. You can claim deductions for:

Mortgage interest (if it's an investment property, not your main home)
Rates and insurance
Maintenance and repairs
Property management fees

Talk to an accountant before renting out your home.

Capital Gains Tax (CGT)

New Zealand doesn't have a general CGT (yet), but:

If you're seen as a property trader or developer, profits may be taxed as income
If you build with the intention to sell (not live in), profits may be taxed

How to avoid: Build with the intention to live in the home, and live there for at least 2 years.

Protecting Your Investment

1. Maintain It

Regular maintenance (Chapter 17) protects value. A well-maintained home sells for 5-10% more than a neglected one.

2. Insure It Properly

Home insurance should cover:

Replacement cost (not market value)
Contents
Liability

Review your policy annually (replacement costs rise with inflation).

3. Improve It Strategically

Some improvements add value. Others don't.

High-return improvements:

Fresh paint (neutral colors)
Landscaping (curb appeal)
Kitchen and bathroom updates (if tired or dated)
Deck or outdoor living area

Low-return improvements:

Swimming pool (expensive to maintain, not everyone wants one)
Over-the-top custom features (e.g., home theater, wine cellar)
Extensive DIY (poor workmanship reduces value)

Rule: Spend $1 to add $1.50-$2 in value. Don't over-capitalize.

4. Know When to Sell

Sell when:

The market is strong (high demand, low supply)
You've lived there long enough to avoid tax (2+ years)
You've outgrown the home or your needs have changed

Don't sell when:

The market is soft (you'll lose value)
You haven't built meaningful equity yet
Selling costs (agent fees, legal fees) outweigh the benefit

Building as an Investment Checklist

Before you build:

Choose a location with strong growth potential
Don't over-capitalize (build to market, not beyond it)
Design for flexibility and future-proofing

After you build:

Get a valuation (6-12 months after completion)
Maintain the home (protect value)
Insure it properly (replacement cost)
Understand your equity position

If you plan to invest:

Talk to a mortgage broker (understand your borrowing capacity)
Talk to an accountant (understand tax implications)
Consider renting it out (if it cash-flows positively)

Your home is your biggest asset. Treat it like one.

Chapter 19: Lessons From Real Builds

Case studies from real NZ builds - what went right, what went wrong, and what you can learn from them.

Case Study 1: The Budget Blowout

The Builder: Sarah and Mike, Auckland
The Plan: Build a 160m² home for $520,000
The Reality: Spent $640,000 (23% over budget)

What Went Wrong

Underestimated site costs: The section was sloped. Earthworks and retaining cost $35,000 (they budgeted $15,000).
PC sums too low: Kitchen PC sum was $20,000. They chose a kitchen for $32,000 (+$12,000).
Variations: Added a deck ($12,000), upgraded to stone benchtops ($6,000), moved a window ($1,500).
No contingency: When costs rose, they had no buffer. Had to borrow more from family.

What They Learned

Get a geotech report before buying the section. If they'd known about the retaining costs, they would've chosen a flatter section.
Lock in selections before signing the contract. PC sums were guesses, not reality.
Build a 10% contingency into the budget. They had none. They should've budgeted $570,000 and aimed to spend $520,000.

The Outcome

They love the house, but they're house-poor for the next 2-3 years (no holidays, no luxuries). If they'd budgeted correctly, they'd have avoided the stress.

Case Study 2: The Builder Who Disappeared

The Builder: James and Emma, Hamilton
The Plan: Build a 180m² home for $580,000
The Reality: Builder went bankrupt halfway through. Had to hire a new builder. Final cost: $620,000 + 4 months delay.

What Went Wrong

Chose the cheapest quote: Three builders quoted $560k-$600k. One quoted $480k. They went with the cheap one.
Builder had cash flow problems: He was juggling too many projects and ran out of money.
No Master Build Guarantee: Builder wasn't an RMBA member. When he went bust, they had no protection.

What They Did Right

Had contract works insurance: The half-built house was covered. They didn't lose everything.
Withheld final payments: They hadn't paid the builder in full, so they had money left to hire a new builder.

What They Learned

Don't choose the cheapest quote. If it's too good to be true, it is.
Check the builder's financial stability. Ask for references. Google them. Check for complaints.
Insist on the Master Build Guarantee. It's worth the extra cost.

The Outcome

They finished the build, but it was stressful and expensive. If they'd hired a reputable builder from the start, they'd have saved time, money, and stress.

Case Study 3: The Perfect Process

The Builder: Anna and Tom, Christchurch
The Plan: Build a 150m² home for $480,000
The Reality: Finished on time, on budget, and with zero major defects.

What They Did Right

Chose the section carefully: Flat, north-facing, all services to the boundary. No hidden costs.
Got a geotech report before buying: Foundation was straightforward (concrete slab, $38,000).
Locked in every selection before signing the contract: Used the Selections Checklist. No variations.
Chose a reputable builder: RMBA member, great references, LBP license, full insurance.
Visited the site weekly: Caught issues early (e.g., window installed in the wrong location - fixed before cladding went on).
Communicated well: Weekly emails with the builder. No surprises.
Did a thorough pre-handover inspection: Identified 8 minor defects (paint touch-ups, squeaky door). Builder fixed them all within 2 weeks.

What They Learned

Planning prevents problems. They spent 3 months planning before signing the contract. It paid off.
The right builder makes all the difference. They paid 5% more than the cheapest quote, but got a smooth, stress-free build.

The Outcome

They moved in on schedule, with no regrets. Two years later, the house is still perfect. They'd build again (and probably will).

Case Study 4: The DIY Disaster

The Builder: Mark, Wellington
The Plan: Owner-build a 140m² home for $350,000 (saving money by managing it himself)
The Reality: Took 2 years (instead of 12 months), cost $420,000, and had multiple defects.

What Went Wrong

Underestimated the complexity: Mark had some DIY experience, but no construction management experience.
Coordinating trades was a nightmare: Plumber didn't show up. Electrician was booked out for 6 weeks. Framer walked off the job (payment dispute).
Didn't get council inspections on time: Foundation inspection was delayed by 3 weeks (inspector was booked out). Had to stop work.
Made mistakes: Installed insulation incorrectly (pre-line inspection failed). Had to redo it ($3,000).
Ran out of money: Underestimated costs. Had to pause the build for 4 months to save more.

What He Learned

Owner-building is a full-time job. Mark was working full-time and trying to manage the build on evenings and weekends. It didn't work.
You need construction knowledge. Watching YouTube videos isn't enough.
The "savings" weren't worth it. He saved maybe $30,000 (vs. hiring a builder), but the stress, delays, and mistakes cost more.

The Outcome

Mark eventually finished the house. He's proud of it, but he says he'd never do it again. Next time, he'd hire a builder.

Case Study 5: The Future-Proofed Home

The Builder: Lisa and David, Tauranga
The Plan: Build a 170m² home designed for long-term living and potential rental income
The Reality: Spent $540,000. Built a home that works for their family now and adapts to future needs.

What They Did Right

Designed for flexibility:
- Ground-floor bedroom and bathroom (accessible if someone becomes mobility-impaired)
- Separate entrance to part of the house (could be rented out or used by adult children later)
- Open-plan living (can be adapted as needs change)
Built above code:
- R3.6 insulation in walls (vs. code minimum R2.8)
- Double glazing throughout
- Heat pump + HRV system (ventilation)
Future-proofed for sustainability:
- Wired for solar panels (didn't install yet, but can add later)
- Plumbed for greywater system (can add later)
- High-efficiency appliances
Spent on what matters:
- Quality kitchen and bathrooms (use them every day)
- Good insulation and glazing (comfort + energy savings)
- Durable exterior (low-maintenance cladding and roofing)
Saved on what doesn't:
- Simple roof design (gable, not complex)
- Standard windows (not custom)
- Basic landscaping (did more themselves over time)

What They Learned

Design for the long term, not just today. Their home works now, but it'll also work in 20 years when their needs change.
Energy efficiency pays off. Their power bills are 30-40% lower than similar-sized homes. Over 20 years, that's $20,000-$40,000 saved.

The Outcome

They've been in the home for 3 years. They love it. It's comfortable, efficient, and adaptable. If they sell, the energy efficiency and design will add significant value.

Key Lessons Across All Case Studies

1. Planning Prevents Problems

The builders who spent time planning (choosing the right section, locking in selections, vetting builders) had smooth builds.

The builders who rushed (chose the cheapest option, left things "to be decided later") had problems.

2. The Right Builder Matters More Than Price

Paying 5-10% more for a reputable, experienced builder is worth it. Cheap builders cost more in the long run (delays, defects, stress).

3. Budget for the Unexpected

Every build has surprises. A 10% contingency is essential. Without it, you'll run out of money or go into debt.

4. Communication Is Critical

Builders who communicated well with their builder (weekly check-ins, written approvals, proactive questions) had fewer issues.

Builders who were passive or reactive had misunderstandings and delays.

5. Owner-Building Is Hard

Unless you have construction experience, a lot of time, and a high tolerance for stress, don't owner-build. Hire a professional.

6. Future-Proof Where Possible

Design for flexibility, build above code, and invest in energy efficiency. It pays off over time.

Final Thoughts

Building a home in New Zealand is one of the biggest projects you'll ever undertake. It's exciting, stressful, expensive, and rewarding - all at once.

The difference between a great experience and a nightmare comes down to:

Planning: Know what you want, what you can afford, and what's realistic.
Choosing the right team: Builder, architect, engineer - hire people you trust.
Communication: Stay informed, ask questions, and document everything.
Flexibility: Things will change. Have a contingency plan.

If you follow the guidance in this book - from choosing your section to moving in - you'll avoid the most common mistakes and set yourself up for success.

You've got this. Now go build your dream home.

Most new residential builds in New Zealand cost between $2,600 and $5,000+ per square metre depending on finish level. A 150 m² home at a mid-range $3,000 per m² is around $450,000 excluding land, consent fees and site extras. See our full cost guide for regional breakdowns.

How long does it take to build a house in NZ?

Allow 12 to 18 months from design sign-off to move-in for a custom build: roughly 3 to 5 months of design, consent and site preparation, then 6 to 10 months of construction depending on complexity, weather and trade availability.

How much deposit should I pay a builder?

Typically 5-10% of the contract price, and keep it at or under 10%. Progress payments should then be tied to completed, verified milestones such as foundations, closed-in, and pre-line, never to calendar dates.

How long does building consent take?

Councils must process a building consent within 20 working days, but requests for further information stop the clock. In practice, allow 4 to 8 weeks, and longer for complex or incomplete applications.

What is a variation and how do I manage them?

A variation is any change to the contracted scope after signing. Get every variation priced and agreed in writing before the work is done, and budget a 10-15% contingency for them - they are the most common cause of budget blowouts.
