A burning people mover was extinguished near Rerewhakaaitu last night.
Firefighters were called to the scene on State Highway 38 just before 9pm.
A fire service spokesman said the van was ablaze and smoke from the fire was drifting across the road, causing a driving hazard.
A police spokeswoman said no one was with the car at the time and they had spoken to the registered owner.
Investigations were continuing, she said.
