Police are urging the driver of white SUV involved in a hit and run west of Kaikohe on Friday night to come forward.
Kerikeri police Senior Sergeant Peter Robinson said the crash occurred about 6.20pm on State Highway 12, near Taheke, as one vehicle heading west went to overtake another.
The driver and passenger of the overtaking car allege the other vehicle swerved across the centre line, causing a collision.
The overtaking car then spun around and crashed into a bank.
The other vehicle, a white Mitsubishi Pajero or similar, did not stop but continued west towards Hokianga.
