"Effective speed management is an essential part of creating a safer transport system, because the speed a vehicle is travelling at directly affects both crash probability and crash severity.
The first new Auckland camera will replace an earlier model camera in Otohuhu in October.
Mr Cliff says Police will publish the locations for the remaining cameras as soon as they are confirmed and the appropriate community consultation and engineering assessments have been carried out.
"Placement of the cameras will be an open process. The site selections are based on robust scientific evidence, and no other reason," Mr Cliff says.
"Police does not receive any money collected from speeding fines, which goes to Government funds.
"What we do know from the research both here and overseas is that speed cameras encourage motorists to slow down, thereby reducing the risk of people being injured or killed in a crash."
Mr Cliff says the cameras will all be placed in locations assessed as having a high risk for speed related crashes, including those where people have died or been injured in crashes involving speed.
"The assessment process uses expert independent analysis based on a decade of crash data, and in-depth knowledge from police and other local traffic experts. We have also taken on board the views of people in communities who are directly affected."
Mr Cliff says about 140 sites in total around the country have been identified as having a high risk of speed related crashes, providing a framework for road safety agencies, councils and local communities to target their enforcement and education efforts in known problem areas.
Funding for the speed camera upgrade project is being provided by the New Zealand Transport Agency through its Road Policing Programme, with Police and the agency to share ongoing operating costs.
As part of a separate project, Police will also pilot a small number of newer generation red light cameras before the end of the year, employing similar site selection methodology to the speed camera expansion project.
