The murderer who raped and tortured schoolgirl Karla Cardno has admitted to the Parole Board he enjoyed the crime.
Paul Joseph Dally, 53, who has spent 24 years in jail for the 1989 killing, was seen by the board on Tuesday.
In the full decision released today, it was revealed Dally did not seek parole and "considerable reservations" were held about him being safe for release.
Dally kidnapped 13 year-old Karla as she cycled to her Lower Hutt home. He raped and tortured her in his nearby home, watching from the window as her frantic family searched outside.
Later he drove to the Pencarrow coast, south of Eastbourne, where he smashed her skull with a piece of driftwood and buried her. Her body was found several weeks later.
After the killing her stepfather, Mark Middleton, campaigned for tougher sentences. He received a nine-month suspended sentence for threatening to kill Dally.
Panel convener Justice Warwick Gendall said Dally was described as a compliant and polite inmate who worked at the offender nursery.
But a number of psychological assessments had indicated he was manipulative, resistant to addressing his offending and had a history of sadistic sexual practices and violence towards females.
"Mr Dally's presentation to the board today, whilst measured and polite, left us with concerns as to his true insight into his crimes.
"It is worrying that he acknowledged in answering questioning by the board that he enjoyed the event and the circumstances of his crime, and the control he could exercise on the child during his dreadful offending."
While Dally had completed all programmes available to him in prison he was still an undue risk to the community, Justice Gendall said.
Parole was declined.
