How to Choose a Builder in Auckland: 10 Checks Before You Sign
Choosing the wrong builder is the most expensive mistake in residential construction, and it is almost always visible in advance. Here are the checks we would run on any builder, including us.
The 10 checks before you sign
- LBP licence verified on the public register, class matches your job
- At least two itemised quotes on identical scope
- Written contract for anything over $30,000, it is the law
- Deposit of 5–10%, not 30%
- References from jobs completed in the last 12 months, and actually call them
- Proof of public liability insurance and contract works cover
- A named person running your job, and how often they will update you
- Payment schedule tied to completed stages, not dates
- How variations are priced and approved in writing
- Who obtains the consent and who books the inspections
Comparing quotes properly
| A complete quote shows | A vague quote says |
|---|---|
| Line items for labour, materials, trades, margin | One number for "the works" |
| PC sums and allowances stated per item | "Allowances included" |
| Exclusions listed explicitly | Silence on what is not covered |
| Fixed price or clear rates for variations | "We will sort it as we go" |
| Timeline with stages | "A few months" |
Contracts, deposits and warranties
For residential building work over $30,000 a written contract is legally required, and the builder must give you a disclosure statement and checklist before you sign. Under the Building Act you have implied warranties on workmanship and materials for 10 years, regardless of any guarantee product. Optional guarantees from trade associations add cover like completion protection, worth weighing on larger builds, but they are not a substitute for the legal basics: licence, contract, insurance.
Red flags that end the conversation
- No licence number offered, or "my mate signs it off"
- Deposits above 20%, or pressure to pay cash
- No written contract offered for a $50,000 job
- Cannot name recent local references
- Quotes that undercut everyone by 30% with a one-line scope
The short answer
Licence on the register, itemised quote, written contract, small deposit, real references. Five minutes of checking beats five months of dispute. A good Auckland builder will volunteer all of it before you ask.

Common questions
What questions should I ask a builder before hiring?
Ask for their LBP licence number, who will run your job day to day, two recent local references, how variations are priced and approved, their payment schedule, and proof of insurance. A good builder answers all six without flinching.
How much deposit should a builder ask for?
5 to 10 percent is normal for residential work in NZ. Deposits above 20 percent are a red flag, your money should follow completed work, through a staged payment schedule, not fund the builder's cash flow.
What should a building quote include?
Itemised labour, materials and trade costs, stated PC sums and allowances, explicit exclusions, how variations are priced, and a staged timeline. If a quote is one number on one page, you cannot compare it and you cannot hold it.
Is a Master Builders or Certified Builders guarantee worth it?
On larger projects the completion cover can be worth having. But the Building Act already gives you 10-year implied warranties on workmanship and materials, and no guarantee substitutes for the basics: a licensed builder, a written contract, and insurance.
What are the red flags when hiring a builder?
No licence number, big deposits, cash pressure, no written contract, no recent references, and a quote dramatically cheaper than everyone else's. Any one of these is a reason to walk away.
