The Christchurch man who fell victim to an apparent hit and run early on Wednesday morning has died.
Warren Noel Blackett, aged 44, of Christchurch, died at 3.40pm this afternoon.
He had been in a critical condition in hospital since he was found with serious head injuries at around 6.30am on Wednesday in the driveway of a home on Yaldhurst Road.
A postmortem will be held tomorrow.
Police are continuing to treat the incident as a possible hit and run, but said it was too early to say if it would be upgraded to a homicide investigation.
Police are appealing for information from the public about the man's movements and the events leading to his injuries.
Detective Senior Sergeant Hill said police were also asking for two youths seen in the Russley area to make contact.
"A witness that has come forward in the past 24 hours has reported seeing two youths, both male with fair hair, running along Yaldhurst Road towards the city in the early hours of Wednesday morning.
"At this stage we don't know whether there's any connection between these people and the injuries sustained by Mr Blackett. We appeal for them to come forward and contact us."
