Spot speed safety cameras

These measure a vehicle’s speed moving towards or away from the camera. They also identify:

  • which lane the vehicle is travelling in
  • the vehicle type, like a car or heavy truck
  • the speed limit for that type of vehicle.

They use infrared flash to see vehicles in the dark. 

Average speed / point-to-point (P2P) safety cameras

These work by calculating a vehicle’s speed along the length of road between 2 cameras. They measure the time the vehicle takes to travel between the cameras and calculate the average speed (distance divided by time).

All future average speed / point-to-point (P2P) safety cameras will use automated number plate recognition (ANPR) technology which reads number plates. ANPR matches a car’s number plate as it enters and exits the average speed measurement zone.

Red light safety cameras

These detect vehicles that don’t stop at a red light. They track a vehicle approaching an intersection, and if the vehicle crosses the stop line when the light is red, they take a photo of the back of the vehicle.

Dual red light/speed safety cameras

As well as detecting red light offences, these detect a vehicle’s speed when travelling through an intersection, to capture speeding vehicles at any phase of the light. International evidence shows these cameras are more effective at reducing deaths and serious injuries at intersections than red light safety cameras alone.

Mobile safety cameras

These work in a similar way to static speed safety cameras, but they sit inside a van, car or trailer so they can be moved around.

Mobile safety cameras won't be signposted, instead we'll use an 'anytime anywhere' approach. 

Mobile phone and seatbelt detection technology

These cameras detect people using their phone or not wearing their seatbelt while driving. They were trialled in Tāmaki Makaurau Auckland for the first time in 2022 but need further trials and a law change before they can be used to detect offences.

Safety cameras don't capture CCTV footage

Our safety cameras don't capture closed-circuit television (CCTV) footage. 

At one of our safety camera sites in Glenbrook, Auckland we’ve installed motion-detected CCTV cameras to test if it will deter vandalism.

We already use motion-detected CCTV technology to protect other types of assets like tolling cameras.

It works in a similar way to a doorbell camera. If motion is detected near the camera the CCTV will be switched on and monitored. If needed, Police will be called and a speaker will let anyone loitering near the camera know we’ve made that call.

Repairing cameras is a waste of limited road maintenance funds that can be better spent keeping our roads safe and well maintained.

We have other traffic cameras across our state highway network.

The number of safety cameras will increase over time. All new safety cameras are carefully tested and must go through a rigorous approval process before they’re used. We’ll calibrate and certify them every year to make sure they’re working as they should.
