A convicted sex offender has won part of his appeal against an earlier sentence of preventive detention.
Peter John Hartley had been convicted at the High Court in Wellington on 18 counts of sexual offending against six teenage complainants, and one of making an intimate video recording.
He was sentenced two years ago to preventive detention.
Hartley appealed his convictions and the sentence.
The Court of Appeal has dismissed his appeal against the conviction.
But it quashed the preventive detention sentence.
The Court of Appeal says he should serve a minimum prison term of seven years on a sexual violation charge.
It has also dropped a name suppression order for Hartley.
