A police officer needed to use a rope tied to his ute's tow bar to reach the driver of a car balancing at the top of a steep drop.
The accident was about 10.10pm on Wednesday on State Highway 10, near the top of Kaeo Hill.
Kaeo fire chief Lindsay Murray said daylight showed the crashed car was securely wedged against a couple of trees but at the time the driver could see only the void below him.
He called emergency services fearing any movement would send his automobile tumbling down the bank.
Mr Murray said it appeared the driver had been heading uphill when he lost control on a section of freshly laid tarseal, skidding across the road and down a bank, coming to rest at the top of a steep drop.
