When someone leaves a laptop on a park bench in Sydney, they probably don't expect it to turn up in a small town in New Zealand.
But that's exactly what's happened to an Adelaide student whose missing computer reappeared in Rangiora, north of Christchurch.
The student's school, which had issued him with the laptop, contacted Microsoft, which was able to track the device's slow passage across the Tasman to a house in the South Island town.
Sergeant Colin Stewart said when officers in Rangiora received a call about the device, they visited the house and quickly confirmed the family that lived there had just returned from a cruise to Sydney.
Their 13-year-old son had found the laptop while there and taken it back home with him.
The computer would be sent back to its owner this week, Mr Stewart said.
