Locking doors, securing windows, keeping blinds closed, or putting valuables out of sight – we all have our ways to protect our homes and families. An effective alarm system acts as an extra layer of protection, helping you feel safe and secure in your home or business. Alarms alert you to intruders, deter would-be thieves, and give you peace of mind when you’re away from home.
However, with hundreds of options on the market and significant price variations, it can be hard to know where to start when it comes to choosing a system for your home.
Here’s our Hines Security guide to the cost of alarm systems in New Zealand – and how to choose the right setup for your needs.
Why should you install an alarm system in 2025?
Your home is your sanctuary, and an alarm system is one of the best ways to keep it that way. Even better? Modern alarm systems include remote access and other smart features, and a wider range of functions.
Here’s what an alarm system offers in 2025.
● Effective protection
An efficient alarm system alerts you to any danger, so you can act quickly to keep your family, home or business safe.
● Visible deterrent
Most burglars will avoid homes with visible security features such as alarms and cameras, reducing the likelihood of break-ins.
● Multi-purpose
Alarm systems now include things like smoke detectors and cameras, meaning you get more for your money and more protection for your home.
● Remote access
If your home security system integrates with your smartphone, you’ll have extra reassurance with alerts, real-time camera footage and the ability to arm or disarm the alarm system remotely.
● Smart features
The latest generation of alarm systems include smart functions, which ramp up protection for your property. Video verification involves sending video footage when an alarm is triggered, so you or your security service can check whether it’s a false alarm or genuine threat.
Smart alarm and video apps are another recent security development. These let you control and manage your alarms and cameras from your smartphone. With features like trigger notifications, live video, and the ability to arm or disarm remotely, they combine the reassurance of an alarm with convenient use and access.
How much does a home security alarm installation cost?
The cost of installing a home security alarm system varies depending on your specific needs and situation. Here’s a look at different systems and what you can expect to pay in New Zealand:
System type | Estimated cost (NZD) | Specifics |

How much does it cost to install a commercial alarm system?
The cost of installing a commercial alarm system in New Zealand varies based on factors such as the size of your premises, the complexity of the system, and the level of monitoring required.
Here’s a guide on what you can expect to pay, based on different systems and scenarios:
System type | Estimated cost (NZD) | Specifics |

What factors influence the cost of an alarm system?
Several factors influence the cost of an alarm system, including:
Type of security system and complexity
There is a wide variety of alarm system options available to suit different needs and levels of complexity. Basic systems are the most affordable, typically costing a few hundred dollars, while more advanced setups with added features can run into the thousands – depending on your specific requirements. Systems with newer features, like video verification and smart apps, may also cost more.
Monitoring services
The cost of monitoring services can depend on your provider and your needs. A basic monitoring service, which responds only if an alarm is triggered, will generally be more affordable than full-service monitoring, which checks that your alarms are armed and gets in touch if anything seems suspicious.

Alarm system installation and maintenance
● DIY installation
Installing an alarm system yourself eliminates labour costs, but it does require some technical knowledge. This option is most common with earlier wireless systems, which are usually easier to set up without professional help.
● Professional installation
Some systems, like hardwired or more complex setups, require professional installation to meet certification or compliance standards. Installation costs generally range from $500 to $1500, depending on the system and property.
● Ongoing maintenance
Regular maintenance is essential to keep your alarm system running reliably. This can include battery replacements, system testing, software updates and general servicing to ensure all components remain functional over time.
Brand of alarm system
The type and brand of alarm system will also have an impact on the price. While cheaper brands may seem appealing, components may not perform as reliably or last as long as better-known brands. They also tend to be more difficult to integrate with your smartphone or other security tools.
Hines Security uses highly-regarded AJAX and Bosch alarms. Both brands are known for their quality and longevity, which makes them a great fit for our business.
How to choose the right alarm system for your home or business
Choosing the right alarm system for your home or business depends on your security needs, property size, budget and personal preferences. With so many factors to consider, such as whether to go for professional or DIY installation and choose basic or advanced features, it can be tough to know where to begin.
The good news? The Hines Security team can help you find the right system for your home.
