The Police Minister says a summer crackdown on speeding is not a revenue-gathering exercise.
Police are enforcing a reduced speed tolerance for two months - extending the crackdown beyond the Christmas/New Year holiday period.
From 1 December until 31 January, police will fine any motorist caught driving more than 4 km/h over the speed limit.
In the past the limit has been enforced from Christmas until 3 January, and on other public holidays and long weekends. A speed tolerance of 9 km/h applies the rest of the year.
Police Minister Anne Tolley says the extension is about making holiday driving safer and is not motivated by revenue gathering.
