It was a lucky escape for a young woman whose vehicle rolled through a fence in rural Hastings at the weekend.
Emergency services were called just before 4pm on Saturday to the crash in Crownthorpe, Hastings.
A police spokeswoman said a car towing a trailer appeared to have lost control, and rolled off Matapiro Road and through a fence trapping the driver.
The woman - in her early 20s - was extracted from the car by Fire and Emergency.She was flown to Hawke's Bay Hospital in a critical condition by rescue helicopter.
A Lowe Corporation Rescue Helicopter spokesman said they had transported the 21-year-old with moderate injuries to hospital. He understood the crash had occurred on private land.
