Officers earlier this month apprehended a driver clocking 104km/h per hour in a 50km/h zone in Christchurch, police revealed on Friday.
During a car show held from March 1 to 3, in which 500 vehicles participated culminating in a main cruise on Saturday night, Sgt Luke Vaughan noted excessive speed and skids were prevalent issues throughout the weekend.
Three people were detained and officers impounded 13 cars, mostly related to unlawful street racing and burnouts.
