Police are trying to find the driver of a stolen ute who crashed into a tractor on State Highway 29A, sending its driver onto the road.
The 59-year-old was taken to Tauranga Hospital in a serious condition after the incident took place near Baypark Stadium between Maunganui Rd on-ramp and Truman Rd, about 4.10pm on Tuesday.
The ute driver fled the scene but an examination was underway.
Head of Western Bay of Plenty road policing Senior Sergeant Wayne Hunter said the tractor driver's injuries were "not life-threatening" but they were yet to speak to the ute driver.
The crash was still being investigated but initial enquiries suggest a man speeding in a stolen vehicle allegedly tried to "underpass" a car immediately behind the tractor and hit it as a result.
