There are hopes that the new speed cameras being installed in Auckland will change driver behaviour.

They measure the average speed a vehicle travels between two cameras and will only ticket drivers if the average speed between them is over the limit.  

Research shows they can reduce road injuries or fatalities by more than 50%. 

Driving safety instructor Tony Williams told Kate Hawkesby that the sophisticated cameras are likely to have an astronomical cost.  

The cameras are being installed at Matakana, Dairy Flat, Redvale, Whitford, Karaka, and Glenbrook, with testing starting in December.
