Two members of the public, who were first on the scene, were reassuring the driver from the road that help was on the way.
After stabilising the vehicle, rescuers abseiled down the bank and extracted the man, who had been trapped for about 30 minutes, the police officer said.
The driver was assessed on the scene and did not have any injuries.
He said the driver was “very fortunate” the ponga trees were there.
The police investigation into the incident continued.
