Understanding the NZ Building Code Smoke Alarm Regulations
In November 2024, significant changes to the NZ Building Code Acceptable Solutions for Protection from Fire (C/AS1 and C/AS2) came into effect. These amendments make interconnected smoke alarms the new minimum fire safety standard for all newly built homes and consented renovations. The goal is to enhance fire safety and improve early detection, ensuring that every household is equipped with a reliable system.
New Building Code Overview
- From November 2024, interconnected smoke alarms will be adopted as the minimum fire safety system in new residential builds and consented renovations in New Zealand, meaning every new home constructed from this date must have either hard-wired or wirelessly interconnected alarms.
- Smoke alarms must be either 10-year long-life battery-operated or 240v mains powered and interconnected.
- Smoke alarms must be installed in all bedrooms, living spaces, hallways, landings and on each level of a multi-level home within 10 metres of each other in any direction.
- Where a kitchen is separated from living spaces and hallways by closable doors, an alarm suitable for kitchens (such as a heat alarm) must be installed in the kitchen.
- Smoke alarms must have both hush and test buttons and be located on or near the ceiling.
- There are very specific requirements about the locations where alarms should and shouldn't be mounted to avoid nuisance alarms, dead smoke areas, etc.
Please note this is only an abbreviated guide, refer to Standard NZS4514 for official specifications. This can be found on the link here.
Building Code Compliant Alarms

Interconnected Smoke Alarm Standards & Placement Locations
The optimal location for any smoke alarm is in the centre of a room, taking into consideration factors such as fans, beams, or other fixtures that may delay detection or cause nuisance alarms. Smoke alarms should not be placed near heat pumps, air vents, or HVAC systems, as these can also lead to false alarms or can alter smoke behaviour. Always follow the manufacturer’s installation instructions and the guidance provided in the Building Code.
To help you stay compliant, we offer a Smoke Alarm Package that meets the new NZ Building Code requirements.
