What to check when hiring extension / renovation contractors in New Zealand
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- In New Zealand, restricted building work must be carried out or supervised by a Licensed Building Practitioner, and all electrical, plumbing, gasfitting and drainlaying by a licensed tradesperson (EWRB for electricians, PGDB for plumbers and gasfitters). Check the public register before you hire.
- For residential building work of $30,000 or more you are legally entitled to a written contract and a disclosure statement setting out the tradesperson's skills, licences and insurance. Ask for both before work starts.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work, and that they are current.
- Get a written, itemised quote with scope, assumptions and a staged payment schedule.
How to judge an extension / renovation contractor
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each tradesperson’s public evidence above.
Verify before you hire
- Extensions and major renovations that affect structure or weathertightness are restricted building work and must be done or supervised by a Licensed Building Practitioner: check the licence on the LBP register (lbp.govt.nz).
- Most extensions need a building consent and a Code Compliance Certificate on completion, plus a Record of Work for the restricted work: confirm all three are in scope.
- A written contract is required by law for work over $30,000; favour a builder who is a Registered Master Builder or Certified Builder and offers a guarantee (Master Build or Halo).
- Residential work carries implied warranties under the Building Act and the Consumer Guarantees Act: check public liability insurance and GST registration too.
Warning signs of a cowboy
- Does restricted building work with no LBP, or isn't on the LBP register.
- Suggests skipping the building consent, or won't help get the Code Compliance Certificate.
- No written contract for work over $30,000, or demands large payments up front.
- Won't provide a Record of Work or proof of insurance.
Questions to ask before you hire
- What's your LBP licence number and class, and is it current?
- Will this work have a building consent and Code Compliance Certificate, and a Record of Work?
- Is there a written contract with staged payments, and do you offer a Master Build or Halo guarantee?
- Do you carry public liability insurance, and what does the warranty cover?
Frequently asked questions
- How do I choose a trustworthy extension / renovation contractor?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. An extension / renovation contractor backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend extension / renovation contractors for payment?
- No. There are no ads and no paid placement. Extension / renovation contractors are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring an extension / renovation contractor?
- Confirm credentials and insurance directly with the extension / renovation contractor, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
