Hiring a builder for a residential project in New Zealand is more structured than most homeowners realise. There are legal requirements around who can do certain work, a licensing system you can check online, and a clear process for getting and evaluating quotes. This guide walks through each step.
Step 1: Check Whether Building Consent is Required
Before getting quotes, establish whether your project requires building consent from your local council.
Building consent is required for most structural work, new builds, additions, and significant alterations. The council issues the consent, inspects key stages of work, and issues a code compliance certificate (CCC) on completion.
Work that generally does not require consent includes some like-for-like maintenance and minor work. Check with your local council — getting this wrong creates problems when you sell.
Your builder can help you understand what consent is required, but the consent application is normally lodged by the homeowner or builder through the local council's system.
Step 2: Check the Builder's LBP Licence
For restricted building work (most structural and weathertightness work), your builder must be a Licensed Building Practitioner (LBP) — or the work must be carried out under the supervision of one.
Check LBP status at: lbp.govt.nz/search
You can search by name or licence number. An LBP's record shows: - Their licence class (Carpentry, Site 1/2/3, etc.) - Licence status (current, suspended, cancelled) - Any disciplinary history
Red flag: A builder who cannot provide their LBP number or whose licence doesn't appear on the register.
Note: Not all building work requires an LBP. For non-restricted work, any competent builder can be hired. But restricted work requires LBP involvement and your builder must supply you with Record of Work documentation.
Step 3: Get at Least Three Quotes
Getting multiple quotes is standard practice for any significant building project. Why three?
- Price variance between quality builders is often 15–30% — this is normal, not a problem
- The lowest quote is not automatically the best — scope differences, material quality, and experience matter
- Comparing quotes reveals whether builders are reading the brief consistently
For accurate quote comparison, provide the same brief to each builder: - Detailed drawings or plans (if available) - Scope of work description in writing - Site access arrangements - Consent status (whether consent has been applied for or granted) - Your preferred timeline
Ask each builder to quote on the same basis so you're comparing like with like.
Step 4: Understand What a Good Quote Includes
A proper builder's quote should include:
| Element | What to check |
|---|---|
| Scope of work | Is it specific? Does it match your brief exactly? |
| Materials specification | What materials are included? Brand/grade specified? |
| Labour rates | Fixed price or hourly? Both approaches are legitimate. |
| Allowances | Are provisional sums (unknown items) clearly identified and realistic? |
| Exclusions | What is explicitly not included? |
| Consent costs | Are consent fees included or excluded? |
| Payment schedule | Deposit, progress payments, and final payment — defined? |
| Liability | What's the warranty on workmanship? |
| Timeline | Start date, completion estimate, key milestones |
Vague quotes with lump sums and minimal detail are a risk. A professional builder will itemise their scope clearly.
Step 5: Check References
Before engaging a builder, check references. Ask the builder for 2–3 recent client references and actually call them. Ask: - Did the project come in on budget? - Were there significant delays? If so, why? - Did the builder communicate well during the project? - Were any issues resolved professionally? - Would you use them again?
Also check: - Google Reviews — search the business name - Registered Master Builders or Certified Builders membership — both organisations have ethical conduct standards - Consumer Affairs/Disputes history — no quick system, but web searches sometimes reveal patterns
Step 6: Use a Proper Contract
For any significant building work, use a written contract. The standard residential construction contracts in NZ are:
- NZS 3902 (Residential Construction): Standard published by Standards NZ — well-balanced for homeowner and builder
- Registered Master Builders contract: Available to MBA members
- Simple letter of agreement: For small jobs, a clear letter confirming scope, price, and payment terms is adequate
The contract should cover: - Full scope of work (reference the quote or drawings) - Contract price (fixed or cost-plus basis, clearly stated) - Payment schedule and conditions - Process for variations (changes to scope) - Defects and warranty period - Dispute resolution process - Insurance requirements (the builder must hold public liability insurance)
Never start work without a signed contract on significant projects. "She'll be right" is not a substitute for documentation.
Step 7: Check Insurance
Before work starts, confirm the builder holds: - Public liability insurance (minimum $1–2 million cover): protects against damage to your property or third parties - WorkCover/ACC compliance: the builder must be registered with ACC for their workers - Contract works insurance (for larger projects): insures the work-in-progress against damage or loss
Ask for a certificate of currency for their liability insurance. A builder who cannot provide this is a significant risk.
Red Flags to Watch For When Hiring a Builder
- No LBP licence for restricted building work
- Unable to provide references
- Vague or very brief quote with a single lump sum price
- Requesting full payment upfront before work starts
- No written contract offered
- Unusual pressure to start immediately without documentation
- Price significantly lower than all other quotes (undercutting often means corner-cutting)
- No physical address for the business
- Not registered with the NZ Companies Office (for company builders) or IRD
