Family spokesman Ben Warren said Mr Warren was a well-respected man who would do anything for anyone.
"He will be sorely missed by family, friends and the local community."
The identity of the 66-year-old, which had earlier been reported, was confirmed by police yesterday morning.
Mr Warren was shot in the driveway of his home in Freyberg Ave on Thursday last week after he allegedly "held and presented" a firearm at police.
He was given medical treatment by officers at the scene and was flown to Dunedin Hospital, where he died on Friday morning.
He had no history with police.
Acting Southern district commander Inspector Darryl Sweeney acknowledged Mr Warren’s death had had a significant effect on the Waitaki community.
"We understand this and so our community will have the opportunity to engage with their local police at upcoming community meetings and events."
The Independent Police Conduct Authority has been notified and a Critical Incident Investigation is ongoing.
The death has been referred to the coroner.
Oamaru Sports and Outdoors co-owner Richard Hill knew Mr Warren, who worked at the store when it was known as Wilsons Sports Centre, for several years.
Mr Hill said he was an "outstanding and well-respected staff member" whose services as a fishing guide were in high demand.
"He was a man that was respected worldwide for the fishing guiding that he did. He was a professional guide and was outstanding at what he did. He had a heart of gold."
Mr Warren also worked at Kurow’s Caltex service station.
The service station’s owner, who did not want to be named, said that
"he has not only been an employee, he has been a family friend. It will affect the town for sure. It will rock the town".
