• In a self-contained caravan, sleep out or similar there must be a minimum of one working smoke alarm.
• In multi-story units there must be one smoke alarm on each level within the household unit.
• Landlords are responsible for making sure smoke alarms are in working order at the beginning of every new tenancy.
• Long life photoelectric smoke alarms are now required where there are no existing alarms.
• When existing smoke alarms are replaced, the replacements must be long life photoelectric smoke alarms.
• Hard wired smoke alarms are also acceptable.
• All smoke alarms must be replaced in accordance with the manufacturer’s recommended replacement date stated on the alarm.




The New Zealand Fire Department recommends photoelectric smoke alarms and long-life batteries – they also recommend an alarm in every room and on every level of a building.
