Smoke alarms are a separate rule

A burglar alarm does not replace smoke alarms. The New Zealand Building Code requires smoke alarms to be a 10-year long-life battery-operated sealed unit or a DC low-voltage or 240 V mains-powered unit, and they must be interconnected. For rental homes, new smoke alarms must be photoelectric, and working older alarms do not need replacing. Check which smoke alarms your home already has before you buy a security kit.

Warranties and installation

Installers may give a workmanship warranty on the work. One Auckland installer offers 12 months, and it is worth asking for that in writing as well as the product warranty. Ask whether the price includes installation and how the system is tested at handover.

Season and timing

October is spring in New Zealand. Plan the installation before the long winter nights of June to August, when outdoor lights and sensors matter most to many households. The price lists show no seasonal change, so the date you need the system working is the main timing factor.

What to put in your request

Give the premises area in square metres, the type of property (house, flat or business), the number of doors and windows to cover, whether you want a monitored alarm, and your city: Auckland, Wellington, Christchurch, Hamilton or Tauranga. Ask whether monitoring is included and what it costs each month.

On BlaBlaPrice you describe the property in a free chat and can add photos. The AI looks through alarm and security suppliers in New Zealand and shows the prices and businesses it finds. Sellers registered on BlaBlaPrice reply in the chat with their offer, and your contacts stay hidden until you decide. See security systems or CCTV cameras.

Questions and answers

How much does a home burglar alarm cost in New Zealand?

Does a burglar alarm replace smoke alarms?

No. Smoke alarms must meet the Building Code rules for their type and be interconnected, so check your existing alarms separately.

Some installers offer a 12-month workmanship warranty. Ask for it in writing as well as the product warranty.
