Police officers in the Hutt Valley had bottles thrown at them while confronting boy racers and bystanders on Friday night.
The officers had to form lines - on Eastern Hutt Road in Taitā - with shields and helmets to force the crowd of 80 back into their vehicles and through a checkpoint.

Hutt Valley area commander Inspector Wade Jennings said police also intercepted a boy-racer meet in Porirua, and about 100 vehicles at Kmart in Petone.
