The death has been referred to the coroner, Mr Gaskin said, who will determine cause of death.
No details of the deceased man will be released until formal identification has been completed and next of kin informed, he said.
Dunedin hunter Murray Edge, 64, went missing in the area last month. He was last seen around 8.30pm on Sunday, April 19 after he became separated from a friend he was night hunting with on a farm about 40 minutes inland from Timaru.
