Ten speed cameras have been disabled in West Auckland and on the North Shore after failing calibration tests, and they might not return to their original spots.
The cameras in Kelston, Green Bay, Titirangi and Takapuna were taken down recently when they failed annual tests, police national manager of crash investigation and calibration services Mark Stables said.
The Kelston camera, on Great North Rd, is one of the busiest in the country.
Wire loops set a certain distance apart under the road trigger the cameras to catch speedsters.
Road works and damage caused by heavy vehicles can alter the loops' distance from each other making them give inaccurate readings.
Stables said police are reconsidering whether the camera spots are the best locations for them. They may be moved to other areas to help reduce crash hotspots.
An audit in conjunction with New Zealand Transport Agency, ACC and local government is underway.
"The principal behind the audit is crash reduction," Stables said.
It can cost up to $60,000 to realign wires so the disabled cameras will be replaced with the cheaper option of digital radar cameras early next year.
Mobile hand-held and phone cameras are being used to catch speeders in the meantime.
