Four people were injured and arrested after a car allegedly being driven at “excessive speed” crashed into a fence after fleeing police in Auckland overnight.

Police said officers signalled for a vehicle to stop in Pakuranga at 2.52am and followed its path from a helicopter after it sped off.

The spokesperson said the police elected not to pursue the vehicle.

“The Air Support Unit has then tracked the vehicle as it allegedly drove at excessive speed through to Mt Wellington, where the driver has lost control and crashed through a fence on Penrose Rd.”

The vehicle travelled around 5km between Pakuranga and Penrose Rd before crashing.

A vehicle allegedly fleeing police was found shortly after crashed on Penrose Rd.

Three people fled the scene and were “quickly” located with the help of the police dog unit.

Four people were treated in hospital for injuries and are in custody.

A Hato Hone St John spokesperson said three ambulances, two rapid response units and an operations manager responded to the crash.

Three patients were taken to Auckland City Hospital in a moderate condition. One person was transported with serious injuries.

Police monitored a vehicle from the air before it crashed in Penrose.

Police say charges are being considered as they continue to make inquiries.
