"Clearly, a lot of the ones we don't find have obviously been used for scrap metal. They have been what we call car ringed," he said.
While some vehicles were taken during home burglaries, Mr van Dillen said cars were generally stolen from public carparks such as at train stations.
He urged people to contact police whenever they saw suspicious behaviour around cars.
The low recovery rate of stolen cars was not just a Wairarapa problem.
It was "generally not that great," he said.
If a car was stolen police recorded the licence plate in their database and staff on patrol were warned to look out for it.
But in some cases, a car could be stolen in the morning and in pieces around the country by the time the owner had finished work for the day, Mr van Dillen said.
If there was CCTV footage of the car being stolen or information was quickly passed to police, there was more they could do.
