Dunedin police are urging residents to keep their vehicles and property secure during the school holidays.

The warning comes after a couple of vehicle break-ins over the past few days.

Senior Sergeant Mark Crawford says a vehicle parked in Mount Cargill Road had its front passenger window smashed.

An iPhone, wallet and cards were taken from inside.

And another vehicle on King George Memorial Drive in Outram was broken into around noon on Saturday.

Crawford says locals should look after valuables, and ensure cars are locked.

He urges residents to report any suspicious behaviour around vehicles.
