Nearly two months on, and the former police detective still hasn't got his prize of a new Isuzu ute.

He told Larry Williams the whole thing is snowballing but no resolution is in sight.

"No closer what so ever. We're just kind of going round and round in circles at this stage".

Event promoter David Baty from OddsOn Promotions is investigating the catch after he put Young through a lie detector test - which Baty claims he failed.

Young said they've been getting calls from everywhere, including polygraph experts from the United States lending their support.

Craig Gubbins from Personal Verification did the test, and said he has no concerns about the results.

"It was highly conclusive, no doubts what so ever. There were 11 questions, they were asked three times so there were 33 questions. We had a lot of data to work with".

Gubbins although said there is an error rate in every test.

"The testing formats that I tend to use have a validity ranging between 89 and 94 per cent so it's not perfect. Polygraphs are not 100 per cent perfect and think that's why people have concerns about them".

Mark Handler from the American Polygraph Association agrees.

"Even if it was a validated technique and performed perfectly under perfect conditions there's still at least a 10 per cent error rate in there".

Gubbins said lie detector tests are prominent in other countries.

"In America it's so common that they often have a polygraph examiner sitting on the waterfront waiting to test people as they get of the boat or sitting at the side of the river waiting to test people".

Dean's brother Lance was on board and said the crew are adamant the catch is legitimate and that he backs his crew "200 per cent".

Lance Young said it could put every fishing competition in jeopardy.

"It's not good for the fishing community right around New Zealand, it's terrible," he said.

"They're going to get people going 'oh I don't really want to fish that competition, you win something you're not gonna get it', so we're just hoping that the guy will just come to grips with himself and pay out."

Tony Baxter was fishing around Dean Young's boat all day, about a hundred metres from Cape Kidnappers.

He said the boats were well within the tournament boundaries when Dean hooked up.

"We actually saw them, they were inside us, we cruised past them and gave them a wave and the thumbs up for their effort. We were pretty rapt for them they all waved back and looked pretty excited".

John Payne was trawling for marlin within the same area as Mr Young - which he said was 50 miles within the tournament boundary.

He was watching as the huge fish was reeled in.

"You could see the boat had stopped and he was playing his marlin so we just fished around that spot at that stage"
