A truck rolled onto its side, trapping its driver, after a crash near the Kamai Range summit yesterday afternoon.
Emergency services responded to the scene of the crash where a truck and ute collided on State Highway 29 between Rapurapu Rd and Hanga Rd on the Matamata side of the ranges.
The truck involved in the crash was blocking a lane and had leaked a small amount of liquid onto the road.
Its driver was trapped for a period of time before being rescued by the Matamata fire crew. He was in a moderate condition when transported to hospital.
The occupant of the ute sustained a head injury and was also taken to hospital.
Emergency services were able to quickly move the truck from the road and directed traffic around the scene.
The Greerton hazmat unit was called to the scene to investigate the potential danger of the leaked substance, but it was determined to be a non-threatening fertiliser.
Northern Fire Communications shift manager Scott Ormond said they initially thought it might be a leak of an agricultural chemical but it turned out to be minor.
"We left the scene in the hands of police to clear up as there was no need for our expertise," he said.
A member of the Greerton hazmat unit said the split substance turned out to be a fertiliser.
"It wasn't anything too nasty. We were just called in case it was something more serious," he said.
