KEY POINTS:
Police are hunting a "dangerous" man who carjacked two women who stopped to help at the scene of an accident.
The public have been warned not to approach Kelly Lee Kamura, 30, of Dannevirke, but to call police if they see him.
He is described as Maori, over 1.8m tall, medium build, last seen wearing a dark hoodie and dark trousers.
Mr Kamura was injured when the car he was travelling in collided with a Fonterra milk tanker on the outskirts of Dannevirke about 12.25am on Sunday.
The car swerved off the road, before ploughing over a bank and exploding in flames.
Detective Sergeant Allan Mullacrane, of Dannevirke police, said two women in their 20s stopped at the scene when they got a puncture after hitting debris created by the accident.
Mr Kamura, who was limping and had blood streaming down his face from the crash approached the women, asking to be taken to hospital, but they said they had called emergency services.
"At that stage he jumped into their car and attempted to drive away," Mr Mullacrane said.
However, one of the women grabbed the keys out of the ignition, angering the man. A witness said the man was "acting crazed" and jumped out of the car confronting the women.
"He hijacked their car and sped off."
Mr Mullacrane said the car had been found a short distance away at a Dannevirke address.
Police now believe he has headed north, possibly to a "safe address" in Waipukurau, Napier or Hastings.
"He's knows we're after him and we would request him to hand himself in," Mr Mullacrane said.
"He's considered dangerous and should not be approached by the public."
Mr Kamura suffered serious head injuries in the accident and would be sporting wounds on his forehead and face, he said.
Hospitals in the region had been alerted.
