What are the smoke alarm rules for NZ rentals?

Smoke alarms are a legal requirement in every rental, under rules that sit beside the Healthy Homes standards rather than inside them. The shape: working smoke alarms are required in the right locations, within a few metres of each bedroom door and on each level of the home, and when alarms are new or replaced they must be the long-life photoelectric type. The precise placement and specification detail is maintained on tenancy.govt.nz.

Who does what

The landlord's job is having compliant, working alarms in place at the start of every tenancy, and replacing alarms that expire or fail. The tenant's job during the tenancy is not tampering, replacing batteries in older removable-battery models where fitted, and reporting problems promptly. In practice the long-life sealed models have made the battery question mostly historical: install those and the division of labour simplifies to "landlord installs, everyone leaves them alone, tenant reports faults".

The habit that keeps it honest

• Test alarms at every routine inspection, it takes seconds per alarm.
• Note expiry dates when installing, sealed alarms have a stated life, usually printed on the unit.
• Record each test and replacement with a date, a one-line entry is enough.

Insurance assessors and the Tenancy Tribunal both treat smoke alarm records as a marker of how a property is run. It is the cheapest good impression in the whole compliance file.
