A senior police officer says former cop Wayne Idour was well known for his ownership of and reference to pornographic material.
Mr Idour has denied he brought and played a bestiality film at a party at Police Commissioner Howard Broad's house more than 25 years ago.
Investigate magazine reported in its latest issue that the bestiality film was screened at Mr Broad's home in 1981 when he was a constable. Mr Broad has confirmed this but said he did not approve and did not watch it.
Police Minister Annette King said Mr Idour, now a private detective, had played the film at Mr Broad's house.
Former policeman Peter Gibbons said it was Mr Idour who was responsible but Mr Idour has denied this.
In Parliament today, Ms King tabled an email from Senior Sergeant John Robinson which she said contained information to back up her view it was Mr Idour who supplied the tape.
In that email, Mr Robinson said he had started work in Dunedin in 1985 and was a relieving photographer when he met Mr Idour who was Team Policing Sergeant at the time.
Mr Idour had been tasked with training police staff and hotel owners on the Sale of Liquor Act.
He had approached Mr Robinson about making a video training tape, wanting the photographer "to dub some short snippets" from a pornographic tape Mr Idour had onto the training tape to make that "more entertaining".
Mr Robinson refused and said he was aware Mr Idour did the dubbing himself, playing the tape to a training session of hotel owners, their wives and staff.
Mr Robinson recalled there was "a complaint of some kind made".
"He (Mr Idour) was a person well known for his ownership of and constant reference to pornographic material."
He wrote the email after watching an item on television about Mr Broad and Mr Idour.
He told NZPA that did not have anything against Mr Idour or have strong views on the allegations, but after watching the television item had recalled the training video incident involving Mr Idour.
He was simply passing on the information and it was up people to make up their own minds, he said.
Mr Robinson, who is now District Co-ordinator: Youth Services in Canterbury, said Mr Idour had been his sectional sergeant for a while in Dunedin.
Ms King today in Parliament attacked Investigate, which she said belonged to a "media sub-culture', and also attacked Mr Idour as a liar.
She said Mr Idour had "hawked" the Investigate story around mainstream media in an attempt to promote the magazine before it went on sale.
Investigate editor Ian Wishart had said he had not identified the informant of his story because the person had a sick family member but he had not "given a damn" about the family members of past targets, she said.
"His informant was outed and subsequently Wayne Idour has had to own up.
"He is a proven liar, he lied to TV3 about working for the Brethren and I believe he is now lying again," she told Parliament.
"I believe he's lying when he said he didn't take the bestiality movie to the party, I believe he's lied when he said he didn't show the pornographic film, I believe that he lied when he said Howard Broad watched it..," she said.
"The reason I believe he has lied is because of the people who are now coming forward to publicly speak on this issue. They don't have to, they have chosen to."
These people included Mr Gibbons who recalled it was Mr Idour who brought the pornographic movie to the party.
"This has been backed up by information I have received today from a serving police officer who is prepared to put his name to it," she said.
Mr Idour initially denied he had been hired by the Exclusive Brethren to trail Prime Minister Helen Clark and various Labour MPs after the last election but it was later revealed that he and a colleague were paid by some members of the Brethren to spy on the Labour MPs.
