A Christchurch man shot a man in the buttocks in what police say was a "very personal and serious attack" remains in a critical but stable condition.
The 55-year-old has serious internal injuries and has undergone surgery after being shot at close range at an Armagh Street flat just after 11am on Friday.
Meanwhile, his attacker is still on the run.
"This was a very personal and serious attack, and the victim's injuries are significant," said Detective Senior Sergeant Darryl Sweeney.
"Detectives were working throughout the weekend and continue to work around the clock in an effort to identify and locate the offender."
Police say they are following positive lines of inquiry but are appealing to anyone who has any information to come forward and speak to them.
A scene examination at the Armagh Street address was completed on Sunday.
Several items of interest were recovered by the forensic team, but police have not yet located the firearm used in the incident.
Anyone with information is asked to contact Christchurch police on 03 363 7400 or anonymously through Crimestoppers on 0800 555 111.
The police armed offenders squad was called in to search for the offender on Friday, but was later stood down.
Police said on Friday the shooting appeared to be "a deliberate, one-off incident" and police did not have concerns about any threat to the wider public.
