Police inquiries are continuing into a series of Thursday night crashes.

There was a three car crash at Tauriko, a truck fire at the Maungatapu roundabout, a car vs Armco barrier on Takitimu Drive and a single vehicle crash at Te Puna Station Road.

The truck fire happened between the Welcome Bay and Maungatapu roundabouts on SH29A about 7pm.

The engine bay was extinguished but the truck and trailer was left in the lane unable to move, which created traffic delays until a heavy haulage vehicle was able to tow it.

Western Bay of Plenty road policing manager Senior Sergeant Ian Campion says the only injuries from overnight crashes were from the 7.17pm Tauriko crash, where a car slammed into the rear of a stationary vehicle waiting to make a right turn into Oakridge Lane.

'The impact shunted the stationary vehicle into the path of an oncoming vehicle. Two people were taken to hospital with what police say are minor injuries.

'Speed is believed to be a contributing factor in the Te Puna single crash at 9.38pm. A vehicle left the road and overturned. No one was injured.”

Ian says police are looking for the driver and passenger of the car that struck the barrier on Takitimu Drive at 10.40pm.

'They left the scene.”
