Police have charged three gang members after an evening of disorder in Kawerau, Bay of Plenty, which saw a police car being crashed into.
Senior Sergeant Tristan Murray said Operation Ram was launched following reports of intimidation, sustained loss of traction, dangerous driving and threatening behaviour by "a small group of gang members" on August 12.
The offenders hit a parked police car with two officers inside, Murray said.
A 30-year-old Kawerau man was charged with disorderly behaviour, assault with intent to injure, driving while disqualified, sustained loss of traction and resisting police.
