A man who was pinned against a house by his own car at the weekend remains in a critical condition in hospital - and police are still searching for those responsible.
The man, aged in his 30s, was pinned against a house on Lupton Rd in Manurewa in the early hours of Sunday morning.
Police spokeswoman Kimberley Mathews said the victim was driving his car in the area before an altercation occurred about 2.30am.
The victim exited his vehicle and the offender - who may have been part of a group - climbed inside, she said.
"The offender then entered the victim's car and crashed the car into the victim, pinning him against the house."
The man was taken to Middlemore Hospital where he remained in a critical but stable condition.
The victim's car was driven from the scene and dumped nearby, where it was later found by police.
Mrs Mathews said police enquiries were continuing, but help from the public was needed.
"Police are interested in receiving any information about the victim's 1996 black BMW 528i sedan acting suspiciously around the Manurewa area between 2.30am and 4.30am," she said.
"Further information is not available until we are able to speak to the victim who is still in hospital with serious injuries.
"We are currently following up on CCTV footage from the area which will hopefully provide us with some more information on the incident."
