Corrections says it has made changes in how it shares information with the Parole Board to help prevent the same mistakes - after questions were raised about the release of an inmate who then brutally murdered a woman.

An independent review found the Department of Corrections provided the right information to another agency about a convicted rapist, months before he murdered a Christchurch woman in her home last year.

The Parole Board maintains the information it was given was inadequate and misleading. Joseph James Brider was released on parole in October 2021 and brutally attacked Juliana Bonilla-Herrera as she slept in her bed three months later.

At a hearing in October 2021, the Parole Board says it was told there was no room available at a residential rehabilitation facility for Mr Brider.

The review also found the Parole Board would have benefited from being explicitly advised the bed had been cancelled.

Corrections chief executive, Jeremy Lightfoot spoke to Māni Dunlop.
