A truck and trailer has rolled on State Highway 3 in Taranaki, causing traffic delays.
Police central communications shift inspector Chris Tate said the driver suffered minor injuries in the crash, about 200 metres from the Waiongana Bridge, just outside Inglewood.
No other vehicles were involved.
Mr Tait said the crash site would take some time to clear, as heavy haulage was needed to right the truck.
"It is causing delays but traffic is able to go through one lane at a time," he said.
