Three motorcycles have been stolen overnight in ram raid on a motorbike shop in Hamilton.

Senior Sergent Peter Van De Wetering says the raid happened at about 3:30 this morning on Anglesea street.

"What appears to be two white vans were used to crash their way through into the gate, into the premises, and they've taken a number of motorcycles," he said.

Van De Wetering says one van was later pulled over by Huntly police, with motorbikes in the back, and four men from Auckland were arrested.

Police are still looking for a second white van, registration AGD816, seen by a witness prior to the robbery.
