Three of Auckland and Northland's worst crash blackspots are about to get fixed cameras as police crack down on speeding drivers.

This month teams will begin to install cameras on Ngapipi Rd in Orakei, Old North Rd in Kumeu and the Twin Coast Discovery Highway in Kaiwaka, Northland.

National manager of road policing Superintendent Steve Greally said the cameras were an important part of the government's Safer Journeys road safety strategy.

"In many cases a crash can be significantly less severe or even completely avoided if the drivers involved reduce their speed.


"Police speed enforcement is just one of the measures which is effective in encouraging safer speeds and reducing deaths and serious injuries on our roads. These new static fixed cameras will go a long way in helping us to do exactly that," he said.

Police had worked with NZTA and an independent transportation sector expert to carefully select the latest sites based on crash risk.

They had developed the Static Camera Site Selection Methodology to pinpoint spots that had a proven history of crashes or potential for crashes resulting in death or serious injury.

"We know they'll make a difference to road safety in the areas," said Greally.

Each camera used the latest digital technology to monitor multiple lanes of traffic in both directions.

New signs were also go up warning motorists were in areas of high crash risk.
