Canterbury drivers are the top offenders in the country when it comes to using their mobile phones and not wearing their seat belts.
Figures released recently show, since 2010, no other region has had more fines handed out to drivers flouting the mobile phone and seat belt laws.
Between 2010 and March this year, there were 15,651 mobile phone fines, and 40,920 seat belt fines given to motorists.
District Commander Superintendent John Price said the figures were high because it was a major focus of police in the area.
"If you go looking for something you generally find it . . . due to the rebuild, we are seeing a lot of tradespeople and others driving large vehicles while using their mobile phones," he said.
