Verified answer: New Zealand Tenancy Services says working smoke alarms are compulsory in rental homes, with location, photoelectric technology and long-life battery or hard-wired requirements for new alarms.
What does the official source say?
- Rental homes must have working smoke alarms within three metres of each bedroom door or in every room where a person sleeps.
- A smoke alarm is required on each level or storey of a multi-level home.
- New alarms must be photoelectric and use a battery life of at least eight years or be hard-wired, while meeting an accepted standard.
What does this mean for smoke alarm selection in New Zealand?
A New Zealand supply proposal should document detector technology, battery life or hard-wired configuration, the claimed manufacturing standard, expiry marking and installation instructions. The landlord and tenant duties described by Tenancy Services should be treated separately from product conformity evidence.
What should a buyer verify before ordering?
- The exact destination jurisdiction, building type and adopted code or regulation.
- The model number, detection technology, power source, battery life, audible output and interconnection behaviour.
- The complete certificate and test-report scope, including product variant, issuing body, edition and validity.
- Required marking, instructions, language, traceability, installation and maintenance information.
- Written confirmation from the responsible authority, approved professional, importer or certification body where required.
