What is a builder's lien in NZ?
Short answer
NZ doesn't have a 'builder's lien' in the same form as Australia or the USA. The closest equivalent is registering a caveat against the property's title — which freezes any sale or refinance — but this is only available where there's a direct interest (e.g., a registered charge). For most unpaid tradie debts, the path is the Construction Contracts Act payment regime, then court enforcement.

- No direct 'lien' law in NZ unlike AU/US
- Caveat possible if you have a registrable interest, rare for tradies
- Better path: CCA Payment Claim + statutory demand + court enforcement
- Mortgages and registered charges take priority over unsecured tradie debts
- Some commercial contracts include a 'right to lodge a charge' as a contractual term
Why no formal lien
NZ deliberately built the Construction Contracts Act as the primary tradie-protection mechanism rather than a lien system. The trade-off: speed (adjudication is fast) for security (you don't get a property charge automatically).
Some commercial contracts give tradies a contractual right to register a caveat against the property if unpaid. Read your contract.
The realistic enforcement path
Issue a proper Payment Claim. If no Payment Schedule, the amount is a default debt. Send a statutory demand under section 289 of the Companies Act if the debtor is a company. Pursue judgment in the District Court if needed.
For ongoing builds, adjudication is faster — decision in ~28 working days, immediately enforceable.
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.
