A call to clog Dunedin streets was taken up by at least 400 boy and girl racers from throughout the lower South Island last night.
At midnight the convoy left its gathering point on Andersons Bay Road, heading south out of the city of State Highway 1.
About 11.50pm, Senior Sergeant Tania Baron said there had been no convoy-related arrests, and the night had not been particularly busy for police.
Earlier in the week they had expressed interest in forming a midnight convoy through the city.
The Dunedin Big Cruise was organised through the internet and on one website more than 1000 people said they would attend.
Police set up checkpoints in central Dunedin, and at Oamaru, but there were few reports of trouble.
Beachlands promoter Matt Stewart wanted to provide a controlled environment for car enthusiasts to rev engines and burn tyres away from public roads, but the police were called after one driver performed doughnuts off the track and damaged club property.
In Oamaru, nine police officers and a vehicle testing officer manned a checkpoint, at which the first infringement notice for vehicle safety was issued in the first hour of operation.
Drivers were breath-tested and vehicles checked in partnership with Vehicle Testing New Zealand.
