A man who raped a woman in her south Auckland home in 2006, has had his minimum sentence in prison reduced three years by the Court of Appeal.
However, Roger Tira Kahui had his appeal against his conviction dismissed and a sentence of preventive detention remained.
Kahui, a relative of Chris Kahui, who was this year acquitted of the murders of his twin sons, was sentenced last year in the High Court at Auckland to preventive detention, with no chance of release for 16 years.
A jury found him guilty of 26 charges including rape, kidnap, sexual violence and indecent assault.
In June 2006, Kahui knocked on the door of his 37-year-old victim's Pukekohe home asking to use the phone, and forced his way inside.
Kahui then beat her up before raping her and committing other sexual acts in her bedroom and living room in what was a 4-1/2 hour ordeal.
He forced her to watch and re-enact scenes from a pornographic film and made her shower on at least two occasions to wash away evidence of his DNA.
Kahui then handcuffed the woman and drove her to a bank to withdraw cash from an ATM machine, but she escaped and ran to a petrol station for help.
During his sentencing, Justice Hugh Williams said society needed to be protected from a man who had more than 120 previous convictions.
Justice Williams said Kahui's past sentences amounted to more than 100 years in jail, albeit imposed concurrently.
He had also shown no remorse and no willingness to rehabilitate himself in any previous visits to jail and the only likely reason his list of offences was not longer was that he was in jail for much of the past 20 years.
In their decision released today, Justices Ellen France, Judith Potter and Alan MacKenzie said Justice Williams had used a sentencing benchmark that was too high for the crimes committed.
"That does not of course mean that the appellant will be released into the community in 13 years' time whatever else happens," they said in their judgement.
"Indeed, he will not be released into the community at all unless and until the Parole Board is satisfied on appropriate evidence that he will not pose an undue risk to the safety of the community or any person."
