A 44-year-old Christchurch man in a critical condition after a suspected hit-and-run this morning has been identified by police.
Officers are trying to work out how the man came to be found lying in the driveway of a home on Yaldhurst Rd, near Riccarton Racecourse, about 6.30am.
Investigators have been conducting an examination at the man's home, not far from where he was found, in an effort to piece together information about his movements.
He is described as European and 1.7 metres tall with a medium build, short red hair, goatee beard and tattoos.
He was wearing red or crimson shorts, a short-sleeved black polo shirt and a grey fleecy jacket.
A cordon surrounded the property on the busy commuter route this morning.
Two police cars were posted outside and a police forensic photographer was at the scene.
Detective Senior Sergeant Tony Hill confirmed the injured man has now been identified, but his name is not being released at present. He remains in a critical condition at Christchurch Hospital.
Police are now appealing for assistance from the public.
"We would like to hear from anyone who has seen this man, or any unusual activity, in the vicinity of Yaldhurst Rd and Racecourse Rd, overnight or this morning,'' said Mr Hill.
