A woman is in Waikato Hospital with serious injuries following a crash on Ohaupo Rd on Wednesday afternoon.
While the crash involved two vehicles, police are also looking for the driver of a third vehicle, believed to be a distinctive light green Ford Falcon.
Witnesses said the Ford cut in front of a north-bound silver Mitsubishi which then lost control and crashed into a southbound car.
The two female drivers, aged 27 and 72, were taken to hospital with moderate to serious injuries.
Anyone with information is asked to contact the Waikato Highway Patrol base on 07 858 6200 or Crimestoppers on 0800 555 111.
