If a carpenter causes damage to your property in New Zealand, you are not left without options. Depending on the circumstances, you may be able to claim through the carpenter's insurance, pursue a dispute resolution process, or seek remedies under consumer and building law. Here's what you need to know.
Your Rights as a Homeowner
When you hire a tradesperson to work on your home, you enter into a contract — even if it's just a verbal agreement or a simple quote. Under the Consumer Guarantees Act 1993 and the Contract and Commercial Law Act 2017, services must be carried out with reasonable care and skill. If a carpenter's work falls short of that standard and causes damage, they are generally liable to put things right.
If the carpenter is a Licensed Building Practitioner (LBP), there are additional protections. LBPs are registered with the Licensed Building Practitioners scheme and are required to carry out restricted building work to a professional standard. You can check whether your carpenter holds a current licence on the LBP register.
What Counts as Damage?
Damage caused by a carpenter can take many forms, including:
- Structural damage — incorrectly cut or removed framing, weakened load-bearing elements
- Water ingress — poor installation of cladding, windows, or doors that allows moisture in
- Surface damage — scratched floors, dented walls, broken fixtures
- Consequential damage — mould or rot resulting from defective work
Some damage is obvious immediately; other issues (like water ingress behind cladding) may not appear for months or even years. This is why keeping records of all work done is so important.
Steps to Take If Damage Occurs
1. Document Everything
As soon as you notice damage, take clear photos and videos. Note the date and write down exactly what you observed. Keep copies of your contract, quotes, invoices, and any written communications with the carpenter.
2. Notify the Carpenter in Writing
Contact the carpenter — ideally by email so you have a paper trail — and describe the damage clearly. Give them a reasonable opportunity to inspect the damage and remedy it. Many disputes are resolved at this stage without needing to go further.
3. Check Their Insurance
Reputable carpenters carry public liability insurance, which covers accidental damage to your property while they are working. Ask for proof of their insurance policy. Some also carry professional indemnity insurance for design or advice-related errors. If they are an employee of a building company, the company's insurance may apply instead.
4. Escalate If Needed
If the carpenter refuses to engage or disputes liability, you have several options:
- Disputes Tribunal — For claims up to $30,000 (or $50,000 by agreement), the Disputes Tribunal is a low-cost, straightforward process. No lawyers are required.
- District Court — For larger claims.
- LBP complaints — If the carpenter is an LBP, you can lodge a complaint with the Licensed Building Practitioners scheme. Disciplinary action can include fines, suspension, or cancellation of their licence.
- Consumer NZ — Consumer NZ has useful guidance on resolving disputes with tradespeople.
Building Consent and Liability
If the work required a building consent and none was obtained, this can complicate matters significantly. Under the NZ Building Code, certain building work requires consent from your local council. If a carpenter carried out consented work without proper approval, both the carpenter and — in some cases — the homeowner may face issues. Always confirm with your local council whether consent is needed before work begins.
For restricted building work (such as structural framing or certain weathertightness work), only an LBP may legally carry it out or supervise it. If unlicensed work caused damage, this strengthens your position when making a claim.
What If the Carpenter Has No Insurance?
Unfortunately, not all tradespeople carry adequate insurance. If a carpenter is uninsured and unwilling to pay, your options become more limited — you may need to pursue them personally through the Disputes Tribunal or courts. This is one of the strongest reasons to always check insurance before work starts.

Preventing Problems Before They Start
| Step | Why It Matters |
|---|---|
| Get a written contract or quote | Sets clear expectations and scope |
| Check LBP registration | Confirms legal authority for restricted work |
| Ask for proof of insurance | Protects you if damage occurs |
| Agree on a defects liability period | Gives you recourse after completion |
| Keep all documentation | Essential for any dispute or claim |
When to Call a Professional
If the damage is significant — particularly anything structural, weathertightness-related, or involving electrical or plumbing systems disturbed during carpentry work — get an independent assessment from a qualified professional before agreeing to any repair. A registered building surveyor or another LBP can provide an expert opinion on the extent and cause of damage, which is valuable evidence if you need to escalate your claim.
