Manawatū police are warning owners of Mazda Demios to take extra care after a spate of thefts in the past week.
Inspector Ross Grantham said there had been a significant increase in unlawful taking of motor vehicles, the vehicle of choice being the older model Mazda Demio.
The vehicles were often driven poorly and crashed causing more damage.
Grantham said owners could take a number of steps including using a steering lock. "They are relatively cheap being purchased from any of the auto parts stores for $30 to $70."
There were more expensive security options such as a car alarm or immobiliser.
