Thieves have stolen more than 150 motorbikes from a warehouse in West Auckland in one night.
The bikes were being stored in Cartwright Road, Kelston, and were packaged in cardboard boxes.
Police believe it may have taken up to six hours to load the stolen motorbikes and take them away, with a hot-wired forklift used to shift them.
The bikes include scooters and child-sized quad bikes, with a total value of nearly $160,000.
A white ute - a 2003 Mitsubishi Triton with registration number BSA579 - was also taken.
Detective Shaun Galbraith said in a statement that the police wanted to hear from anyone who was in the area between 9pm Sunday and 4am Monday.
"Whoever has done this is obviously going to try and sell them and we need people to be vigilant," he said.
"If you see a bike like this for sale and you suspect it may be stolen, please let us know. It's also a warning to anyone who's offered one of these bikes and buys it - you're buying stolen property and you run the risk of being criminally charged."
