Speed, alcohol and a lack of seatbelts were all likely contributing factors to the "horrible" Wellington crash which killed a teenage girl.
On Wednesday evening the car, carrying three teenagers, careened off the road at Shelly Bay and landed on the rocks below.
A 17-year-old girl died at the scene, and two boys aged 17 and 18 were rushed to hospital.
The 17-year-old remains in intensive care in a serious condition, while the 18-year-old has been discharged.
Inspector Wade Jennings told The Herald today investigations were ongoing but it was "highly likely" speed and alcohol were involved as well as a lack of seatbelts.
