Detective Senior Sergeant Virginia Le Bas says she was unable to prove the man was Peter Graham, 51, a tourism operator missing from his Christchurch home since Sunday, or if there had been any foul play involved.
"We're just going through our investigations and should know more after a post mortem tomorrow," she told NZPA tonight.
Graham had not contacted family or friends since the weekend and those who knew him described this as out of character.
The body was found in Blighs Gardens, South Brighton.
