Police are throwing the book at a couple of bikers who swarmed Auckland City on New Year's Eve

Dozens of bikers converged on the city, executing dangerous manoeuvres and damaging a police patrol car.

Two arrests have been made and five bikes have been impounded following what Police describe as appalling and reckless driving behaviour.

Two men will appear in court in the coming days -- one for careless driving and failing to stop and the other for traffic offending, including driving without a licence.

Jacqui Whittaker from Auckland City Police says the driving was completely unacceptable and put the lives of innocent members of the community at risk.
