Investigative journalist Ian Wishart says he would be happy to talk to police about an article in his magazine which suggests Swedish tourist Heidi Paakkonen could still be alive 21 years after she went missing.
David Tamihere was sentenced to life imprisonment in 1990 for the murders of Ms Paakkonen and her fiancée Urban Hoglin in the Coromandel in 1989.
Mr Hoglin's body was found by pig hunters in Coromandel bush two years after he went missing but Ms Paakkonen's body was never found.
An article in today's Investigate magazine suggested she was still alive when police began searching for her, and in the company of a man who was not David Tamihere.
The magazine claimed to have obtained a confidential briefing sent to former police commissioner John Jamieson which suggested Ms Paakkonen was kept alive after Mr Hoglin's death and transported nearly 300km by road, and then boat, to Kawau Island in Auckland's Hauraki Gulf.
A police spokesperson told NZPA police were not prepared to comment on the article unless they saw Mr Wishart's information, in which case it would be assessed by the national crime manager.
Mr Wishart said he would be happy to discuss the magazines findings with the police.
