Almost half of all tickets from speeding cameras are given out in Auckland, prompting the Automobile Association to urge the police to ease up on targeting low-level speedsters on Auckland motorways and instead focus on higher-risk roads around the country.
The cameras and a decision to lower, over holiday breaks, the usual 4km/h tolerance - and this season even to scrap it - have resulted in a boom in tickets. Twenty-six thousand more were issued each month last year on average than in 2009. That is despite police saying average speeds have dropped.
Last year, an average of 82,000 speeding tickets were issued each month, compared to 56,000 five years before. Much of the increase is down to the crackdown on low-level speeding over holiday periods.
Lower speeds and fewer drink-driving offences have also resulted in a drop in traffic-fine revenue. Last year, the figure was $71 million - the lowest in 15 years and down from a high of $105 million in 2004. Most of that was from speeding fines.
Road policing chief Assistant Commissioner Dave Cliff denied staff were using speed cameras to gather revenue, saying they did not benefit from the money raised; it went into the Government's coffers. It also cost the police to process fines - money they did not recoup from the proceeds.
"Police don't measure success by fines, but by fewer road deaths, fewer injuries and fewer victims, and in 2013 we saw the lowest road toll for 60 years," Mr Cliff said.
