KEY POINTS:
Police have interviewed two television psychics in the hope of gaining a lead in their inquiry into the disappearance of Wellington woman Kaye Stewart in 2005, saying they will look at "any little piece of information" anyone can come up with.
Mrs Stewart, 62, a physiotherapist from the Wellington suburb of Northland, vanished when walking in Rimutaka Forest Park.
Police say they are now "80 per cent" certain Mrs Stewart was murdered, and her family agree.
The interview with Sensing Murder psychics Deb Webber and Kelvin Cruickshank will screen as part of Tuesday's show.
Producers said Ms Webber had named a person involved in the inquiry but police said they had already discounted that person, and other publicly unknown information revealed by the pair had failed to produce any fresh leads.
"I'm sitting on the fence (regarding psychics)," Detective Senior Sergeant Ross Levy told the Dominion Post.
"When you're dealing with a mystery and foul play is seriously suspected, we will look at any little piece of information anyone comes up with."
Mrs Stewart's husband, Bob, said it was more important to raise public awareness than to debate the reality of psychic powers.
Prominent defence lawyer John Billington, QC, said he doubted that a psychic's evidence would be admissible in court.
"Well, it's not a fact, is it? I would be very surprised if the law even allowed it."
Though police received many tips from self-proclaimed psychics only a few had ever led anywhere.
More than 100 people in the area of the park where Mrs Stewart disappeared have been questioned as part of the inquiry, but there are no likely suspects.
Police exhaustively searched the area where Mrs Stewart went walking, but found nothing that belonged to her.
A $50,000 reward for information had little response.
