How do I cancel a building contract in NZ?
Short answer
Residential building contracts have a five-working-day cooling-off period from signing under Section 362J of the Building Act — you can cancel for any reason in writing without penalty. After that, cancellation depends on the contract's termination clauses and any breach by the other party. Stop-work and termination always need legal advice for anything over $60k.

- Five working days — statutory cooling-off period (Section 362J)
- Must cancel in writing within that window
- Builder must refund any deposit paid
- After the window, only contract-based or breach-based termination
- Wrongful termination by you can trigger damages claim
The cooling-off rule
Section 362J gives the homeowner the right to cancel a residential building contract for any reason within five working days of signing. The cancellation has to be in writing. The builder must refund any money paid except any costs the builder has already incurred (and even those have to be itemised).
If the cancellation period wasn't disclosed in the contract or the s.362H disclosure document, the cancellation right extends — talk to a lawyer about how long.
Terminating after the cooling-off period
Read the contract's termination clauses. Most NZS-style residential contracts allow termination for: persistent breach with notice and time to remedy; insolvency of the other party; supplier insolvency disrupting supply; force majeure events.
Walking off because you've changed your mind — that's wrongful termination and the builder can claim damages (lost profit, mobilisation costs).
If the builder is the one breaching
Document the breach in writing. Give written notice citing the contract clause and the time to remedy. If the builder doesn't remedy within the time, terminate in writing.
Don't tell them to stop work verbally and assume the contract is over. That trips a wrongful-termination defence.
Knowing the rules is half the job. The other half is knowing who you're hiring. Check any NZ builder against the public record: company status, licensing and insolvency notices, from the official NZ sources.
