"The most common cause is just general use, wear and tear and, of course, when things go wrong with pursuits. While there are fewer of those incidences, the expense involved tends to be higher."
Mr Sutton said incidents where damage did occur were investigated by police to assess liability.
"Damage is taken seriously and obviously any incident where damage is caused, we do look into why that incident took place and the potential liability associated with that."
Mr Sutton said Wairarapa roads also contributed to vehicle damage, although that wasn't a common cause.
"In terms of our roads, it comes back to use. Our roads are mostly rural and there are a number of sealed and unsealed roads that we do have to travel across so there is the potential for damage to be caused due to that, but that is probably no different to an urban environment and the wear and tear those roads can cause," he said.
The data also showed a total of nine vehicles were completely written off over the six years.
Nationwide, more than $12.7 million was spent on fixing police vehicles from 2009, while 126 vehicles were rendered irreparable.
As of July 2013, there were 3200 police vehicles in operation throughout New Zealand - including police speed camera vans.
NZ Police Association president Greg O'Connor said police had experienced problems with people deliberately damaging their vehicles, driving up repair costs.
"Those figures are not really surprising, considering how many thousands of hours are done on the road and particularly since, recently, so many of the pranks have been people deliberately ramming police cars. It has been an issue, particularly with boy racers," he said. NZME
