Police Minister Judith Collins has ruled out a call by the Automobile Association for police to use road signs to alert drivers to speed cameras.
New figures show the number of tickets issued by police has nearly doubled.
There were nearly 628,000 infringements in 2010, almost twice as many as 2009 and more than 200,000 above the four-year average.
The country's 55 speed cameras issued 200,000 tickets in the first four months of this year.
AA motoring affairs general manager Mike Noon said the public was concerned the cameras were for revenue gathering, rather than safety.
Instead of having hidden speed cameras, there should be signs in place to alert motorists, he said.
Collins said today the rise in the number of tickets was partly because of the improvement in camera technology.
New digital cameras gave much clearer images than the old film cameras and didn't break down as much.
There were also lower speed tolerance levels over holiday weekends, she said.
Despite criticising speed cameras as a revenue gathering mechanism while in Opposition, Collins said fines did not go to police.
Police would not be erecting signs to warn drivers.
"What we've found over the years is that when there's a big warning sign, people just slow down for that little bit and then they speed up again."
Driving was not a game and roads could be dangerous, she said.
"People need to take some personal responsibility. If they're not breaking the speed limits, then they won't get a ticket."
