Smoke Alarms and Safety Requirements in NZ Rentals
Published: 23 October 2026
Working photoelectric smoke alarms are a mandatory legal requirement in every New Zealand rental home, alongside Healthy Homes compliance and landlord insurance conditions.
Key Takeaways
- • All new or replacement alarms must be long-life photoelectric or hardwired
- • Alarms must sit within 3 metres of every sleeping area door and on every level of the house
- • Landlords must ensure alarms are working and in date at the start of each new tenancy
- • Missing or tampered smoke alarms can void fire insurance claims and attract Tribunal fines
Required smoke alarm specifications
Under the Residential Tenancies (Smoke Alarms and Insulation) Regulations, whenever a smoke alarm is installed or replaced in a rental property it must be a photoelectric alarm with a long-life (at least 8 years, typically 10 years) non-removable sealed battery, or a hardwired smoke alarm system.
Alarms must comply with Australian Standard AS 3786:1993 (or a subsequent or equivalent international standard such as UL217, CAN/ULC S531, EN14604 or ISO12239) and must be installed according to the manufacturer's instructions (on or near the ceiling, clear of dead-air corners).
Placement rules: the 3-metre rule and multi-level homes
- • There must be at least one working smoke alarm within 3 metres of every sleeping area door, or inside every room where a person sleeps
- • In a multi-storey or split-level home, there must be at least one working smoke alarm on every level or storey, even if there are no bedrooms on that level
- • In self-contained sleepouts, minor dwellings or caravans included in the tenancy, a compliant alarm must also be installed
Landlord vs tenant responsibilities
The landlord is responsible for making sure all smoke alarms are in working order at the beginning of every new tenancy and for replacing expired or faulty units during the tenancy. Every smoke alarm has an expiry date stamped on its casing — an alarm past its expiry date is non-compliant even if it still beeps when pressed.
Tenants must not remove, disconnect or tamper with any smoke alarm, and must notify the landlord or property manager as soon as they notice a fault. At Climber, our inspectors check and photograph smoke alarms during every routine property inspection.
Questions landlords ask
What type of smoke alarms are legally required in NZ rentals?
New or replacement smoke alarms must be photoelectric with a long-life (minimum 8-to-10 year) non-removable sealed battery, or hardwired into the building's electrical supply.
Where must smoke alarms be installed in a rental property?
Within 3 metres of every sleeping area door (or in every room where a person sleeps) and on every level or storey of a multi-level home.
Who is responsible for testing smoke alarms during the tenancy?
The landlord must ensure all alarms are working at the start of every tenancy and replace expired alarms. Tenants must not remove or tamper with alarms, must replace replaceable batteries if any older compliant units exist, and must report faults immediately.
