The driver of a white vehicle fled the scene after hitting a woman as she was walking her bicycle across an Auckland road last night.
The woman is in a serious condition in Middlemore Hospital after the incident.
She was walking her bicycle across Aviemore Drive in the suburb of Highland Park at about 9pm when she was struck by the white vehicle.
Witnesses described the vehicle as a white four wheel drive, or similar, and said it immediately left the scene.
Police want to speak to anyone who has information about the incident.
