Australian police are assessing claims that a New Zealander convicted of Norfolk Island's first murder in 150 years may not have acted alone.
Nelson chef Glenn McNeill is behind bars for killing Janelle Patton, 29, on Easter Sunday in 2002.
McNeill, who confessed to stabbing Ms Patton,
was sentenced to 24 years' jail in 2007.
But he now claims the only part he played in Ms Patton's murder was dumping her body.
He gave the names of people he claims are responsible for the murder to documentary-maker Bryan Bruce.
McNeill claims the married couple were drug dealers who forced him to dump Ms Patton's body under threats of violence.
Bruce, after a lengthy investigation that included travelling to Norfolk Island, met Australian Federal Police in Wellington this week to hand over the information.
The information included a statement from McNeill outlining his part in the murder, the names of the alleged drug dealers and a report from a New Zealand pathologist who concluded that Ms Patton was restrained and killed by more than one person.
"There was a whole lot of other information that I'm not going to tell you about that I tabled with the AFP," Bruce said.
"I'm not holding a candle for Glenn McNeill ... If the police find that there's absolutely nothing here and it's all explicable, then that's fine - I've done my job.
"But if they do find something and these other people are brought to account, that's fine too and I've done my job even better."
