Auckland Transport road safety manager Karen Hay said red-light running was a serious crash risk and the CBD trial showed the benefits of broadening the cameras' reach.
There were 387 injury causing crashes caused by red-light runners at intersections within the former Auckland City boundaries between 2001 and 2005, far more than anywhere else in the country.
The Ministry of Transport says it will draw on a range of research including the Auckland results before completing a national policy on red-light cameras by April.
Spokesman Barry Kidd said the Government still needed to evaluate how the cameras would fit into a mix of road safety tools, where else they would be appropriate and where the responsibility would rest for paying for them.
AA motoring affairs general manager Mike Noon said the trial results showed there was no reason to delay rolling out cameras throughout the country any longer.
"Red-light cameras have proved themselves - they work, they are cost effective and they have public support," he said. "The AA can see no reason not to act now and use these cameras to make our city intersections safer for all road users."
