At Hitchcock's sentencing in December 1996, the court heard how he used an axe to murder a 26-year-old woman, and then tried to rape her young daughter, which involved dragging her around her Oamaru home with a cord around her neck.
Both victims' names are permanently suppressed.
Hitchcock committed the horrifying crimes just two months after being released from prison, a sentence he received for sexual offending.
In November, the Parole Board heard that despite hundreds of counselling sessions, the prisoner was still regarded as a medium-high risk of sexual and violent reoffending.
The murder victim's sister said that alone should prove Hitchcock was unfit for release, and she planned to argue precisely that point before the board in March.
"Nothing has changed," she said.
"It's certainly wrecked our family ... It's always in our minds. It's never going to go away."
Hitchcock undertook intensive sex-offender rehabilitation in 2015 but board chairman Sir Ron Young noted his behaviour was described as concerning and aggressive.
The killer spent a brief period outside prison after heart surgery several years ago, but staff became so worried about his "escalating and imminent risk" he was returned to jail.
Hitchcock told the board at his last appearance he had worked hard over the past six years and had a good reputation behind bars.
He had completed seven guided releases and he argued he should be released to a facility, the name of which was withheld in documents released to the ODT.
"The letter we have [from providers] suggested that there was a bespoke programme that had been prepared for him to deal with his particular risks," Young said.
"We have not seen such a programme and therefore have no idea of its content."
Understanding the specific arrangements was crucial and Young asked for the information to be provided to the Parole Board before the March hearing.
For the friend of the murdered woman, Hitchcock's release remained unthinkable.
"This isn't revenge. I'm not a vengeful person, but I'm for justice. Life should mean life."
