A mini bus carrying 13 passengers has crashed on State Highway 5 in Rotorua.
Rotorua constable Russell Lyle said emergency services were called at about 8.26am.
He said the vehicle was travelling south towards Rotorua when one of the front tyres punctured which caused the vehicle to travel across the centreline and towards the northbound lane and onto the grass.
There were no reports of injuries.
Mr Lyle said there was a temporary closure to the northbound lane with "stop" and "go" signs directing traffic. Police were still on the scene.
