MP and former broadcaster Maggie Barry says she was groped by Rolf Harris during an interview in the 1980s.
Barry said she was conducting a radio interview with Harris, when he slid his hand up her thigh, she told RadioLive today.
Barry said Harris turned nasty after she rebuffed his advance and called him a "creep".
"In the studio he started to do the old wandering hands thing and I stood up and I said 'well you can stop that right now'," she said.
"For a few moments I just saw his really nasty side."
Harris, 84, was found guilty in London this week on 12 charges of indecently assaulting four girls over nearly 20 years from 1968.
The Australian-born entertainer is to be sentenced in Britain overnight (NZ time).
He is the second person to be convicted under the British police Operation Yewtree, which was set up following the Jimmy Savile scandal.
Witnesses from New Zealand and Australia gave evidence at the trial, but Harris was not charged with offences against them as the court did not have jurisdiction to prosecute incidents that took place outside Britain.
New Zealand police were now investigating whether Harris could face similar charges for crimes allegedly committed here.
Barry told RadioLive this morning that her experience during the interview could have been different had she been younger.
"If I'd been a young person and had been uncertain or maybe over-awed a little bit by his celebrity status I think it would have been a very different experience," the National MP said.
"I think ... he will get the full force of the law and probably die in jail and he deserves it."
