The Parole Board has refused to release the convicted murderer Teina Pora, as attempts to have his convictions overturned continue to gain momentum.
Pora has spent 20 years in jail for the murder and rape of Susan Burdett in 1992, a crime he claims he didn't commit.
The board's report said Pora has support from others, including those who believe he is innocent, but that is not something it is able to consider.
It says Pora broke prison rules in January by having prohibited items in his cell, including a lighter and screwdriver and an objectionable item.
The board says that while Pora has made considerable progress, this was a setback.
It says he also has to work at satisfying the board that he can manage in the community without incident or undue risk.
