Corrections is reviewing the supervision of the man who murdered Christchurch caregiver Amy Farrall while he was on parole.
Aaron Rhys McDonald, 38, pleaded guilty yesterday to Ms Farrall's rape and murder, and to dumping her body in the boot of her car at a Woolston supermarket on March 29.
After the murder, he fled to the West Coast where he picked up two hitch-hikers, Michaela Brandl and Niki Honda, near Franz Josef.
Armed with a metal bar, he robbed them of their belongings and attacked them.
He pushed Ms Honda, of Dutch-Japanese origin, from his moving 4WD before stabbing Ms Brandl, a German, in the neck three times. He pleaded guilty yesterday to charges of intent to cause grievous bodily harm.
He also admitted a minor charge of operating a motor vehicle recklessly, as he tried to evade police before being arrested after a five-hour stand-off.
Some of Ms Farrall's family members were in court to see McDonald on an audio-visual link. Wearing green prison clothes, he said: "Guilty your honour."
McDonald also lost his name suppression and will be sentenced on July 24.
He was on parole at the time of the crimes, a Parole Board decision shows.
McDonald had been sentenced at Palmerston North District Court in May 2009 to five years and three months in custody for multiple crimes, including the manufacture of methamphetamine, burglary, theft and arson.
Jeremy Lightfoot, National Commissioner of Corrections Services, yesterday said initial inquiries showed that McDonald had met his parole conditions up to the point of his last reporting to them on March 18 this year.
"Our probation staff were in regular contact with him and those he was living with," Mr Lightfoot said.
A comprehensive review of his management is being made "to ensure his supervision in the community met all our standards and expectations", he said.
"This comprehensive review is not complete yet, and as we will also be giving advice in regards to sentencing options for this offender it would not be appropriate for us to comment before he is sentenced."
A hearing at Rimutaka Prison last September was told McDonald was a self-confessed alcohol and methamphetamine user who smoked cannabis daily since he was 15, but his risk to the community over the remaining nine months of his sentence could be "adequately mitigated".
McDonald told the board that he had accommodation available in Christchurch and there was a chance of working with a friend there. "This seems to be some way off at the moment," the decision said.
