🏗️ How to Hire a Builder in NZ (2026)
Hiring the wrong builder can cost far more than the job is worth — defective work, unpaid subcontractors, and buildings that fail council inspection. This guide walks you through every step to hire a safe, licensed builder for your NZ home project.
Step-by-Step: Hiring a Builder in NZ
- Define your project scope Write down exactly what you want done — even roughly. Include approximate size, materials preference (if any), and whether you need consent. A clear brief gets you better quotes and prevents disputes about scope later.
- Decide if an LBP is required Restricted building work under the Building Act includes structural framing, foundations, weathertightness (cladding, roofing, windows), and certain work in multi-storey buildings. These must be carried out or supervised by a Licensed Building Practitioner (LBP). Most professional builders hold an LBP, but always confirm.

Check the LBP register
Before calling anyone, verify their licence at lbp.govt.nz. Check:
- Licence is Current (not expired or suspended)
- The licence class covers your work (Carpentry for framing, Site 1/2 for supervision)
- No active or past disciplinary actions
- Check if building consent is needed Most structural work, extensions, and new builds require building consent from your local council. Your builder should advise — but ultimately it's the homeowner's responsibility to obtain consent. Expect 3–6 months from engagement to consent being issued, and $2,000–$8,000+ in fees.
- Get 3 written, itemised quotes Contact at least 3 builders. Give each the same brief and ask for a written quote specifying: fixed-price or cost-plus, inclusions and exclusions, consent (in or out?), payment schedule, and an estimated completion timeframe. Don't choose on price alone.
- Check references and past work Ask for 2–3 references from similar jobs completed in the last 2 years. Call them — ask whether the builder finished on time, within budget, handled issues well, and whether they'd hire them again.
- Sign a written contract For any job over $30,000, insist on a proper contract. Standard NZ building contracts are available from the Building Industry Federation. The contract must cover: scope of work, price and payment schedule, variations process, defects liability period, and dispute resolution.
- Get a Record of Work on completion For restricted building work, your LBP must provide a Record of Work on completion. This documents what restricted work they carried out. File it with your consent documents and building CoC — you need it for insurance and resale.
⚠️ Red Flags — Walk Away
- Can't provide an LBP number or won't confirm their licence class
- Cash only, no GST, no invoices
- Won't provide a Record of Work ("most people don't bother with that")
- Asks for more than 20% upfront on a large job
- No evidence of public liability insurance
- Refuses to put the quote in writing
- Significantly cheaper than every other quote with no explanation
- Pressure tactics — "I need to know today to hold the start date"
✅ Signs of a Good Builder
- Provides LBP number and licence class without being asked
- Walks you through the consent process and advises what's needed
- Quote is itemised — labour, materials, subcontractors listed separately
- Milestones-based payment schedule (not arbitrary weekly invoices)
- Happy to provide references from recent similar jobs
- Explains variations clearly and in writing before proceeding with changes
- Carries public liability insurance — shows you the certificate on request
Fixed-Price vs Cost-Plus — Which Is Better?
Fixed-Price Contract
Builder quotes a set total for an agreed scope. You have price certainty. Builder carries the risk of material/labour overruns. Best for: well-defined scope, new builds, kitchens.
Cost-Plus Contract
You pay materials at cost plus an agreed margin or hourly rate. Transparent, but scope creep is your financial risk. Best for: complex renovations, heritage homes, unknowns under the floor.
Whichever you choose, define the scope clearly in writing. Scope creep is the most common source of building disputes in NZ.
Payment Schedule Best Practice
Never pay in full upfront. A standard payment schedule for a residential build:
- 5–10% deposit on contract signing
- Progress payments tied to verified milestones (slab poured, frame up, roofed, lined, painted)
- 5–10% retainage held until a 3-month defects period expires

Do I need an LBP for all building work in NZ?
Not every type of building work is restricted, but most structural, weathertightness, and foundation work is. An LBP isn't legally required for non-restricted work (e.g., internal non-structural fit-out), but most professional builders hold an LBP anyway. If you're unsure whether your project is restricted, check MBIE's guidance at building.govt.nz.
How do I check a builder's LBP licence in NZ?
Search the public register at lbp.govt.nz. Check the licence is Current and the class matches your job — Carpentry LBP for framing work, Site 1 or Site 2 for overall site supervision on larger projects.
Who is responsible for getting building consent?
The homeowner (or their agent) is the applicant for building consent — not the builder. However, your builder can prepare or manage the application on your behalf as part of their service (and many do). Always clarify upfront whether the builder is including consent in their service, or whether you need to arrange it yourself or hire a designer/drafter to handle it.
What is a Record of Work from a builder?
A Record of Work is a document an LBP must provide to the building owner after completing restricted building work on a consented project. It lists what restricted work they personally carried out or supervised. You give a copy to your council with the Code Compliance Certificate application. If a builder won't provide one, that's a serious red flag.
How much should I budget for a kitchen renovation in NZ?
A mid-range kitchen renovation (new joinery, appliances, plumbing, and electrical) typically costs $25,000–$60,000 in NZ, depending on size, specification, and city. The builder's labour component is roughly 30–40% of the total; joinery and appliances make up most of the rest. For full cost breakdowns by city, see our Builder Cost Per Hour guide.
