An Arrowtown murderer who was brought to justice 16 years after the killing is drug-free and making "excellent progress" on parole, a report says. But that was not enough for Parole Board chairman Sir Ron Young to allow 48-year-old Jarrod Allan Mangels to be free of his GPS tracker.
"Thiswas a particularly horrific murder," he said.
"Mr Mangels has had his struggles in coping in the community after almost 18 years in prison and a long history of violent offending and although he is doing well, we still think it important that we monitor compliance with the geographical restriction."
Mangels strangled his neighbour Maureen McKinnel in Arrowtown on Boxing Day in 1987.
The 38-year-old victim's naked body was found five days later, dumped under the Arrow River bridge but the case was only solved in 2003, when scientific advances meant the killer's DNA could be matched with that found under the woman's fingernails.
The board, at a final progress meeting last week, heard the killer had stable accommodation and was working on a dairy farm.
Because of Mangels' "excellent progress", Young cancelled the 10pm-6am curfew he had been subject to.
However, a bid to change the bounds of his exclusion zone and come off the GPS tracker was declined.
"Mr Mangels did not have any compelling reasons. We contacted some of the victims before [his] hearing today and their feedback was to strongly oppose any change to the geographical restriction and so we refused that application," said Young.
However, he said the restriction would end in August.
Mangels was released last year despite claims he was unable to remember his murderous attack.
He said a head injury he sustained after a clash with a gang in 1999 meant he had no memories from before then.
