Police arrested three people and seized 13 cars for doing burnouts during the Chrome car show in Christchurch.
They also summoned a further 11 people to appear in court and issued more than 30 speeding fines, with one person caught at 104km/h in a 50km/h zone and several others doing in excess of 80km/h in the same areas, Sergeant Luke Vaughan said.
The show ran over the March 1-3 weekend and attracted more than 500 vehicles and enthusiasts, Vaughan said.
