Popo was now on the waitlist for a Medium Intensity Rehabilitation programme, which was "clearly an appropriate next rehabilitative step for Mr Popo to take", the decision said.
Popo told the board he was not actively seeking parole and did not supply an address where he might live if granted parole.
However, he would prepare a release proposal including a proposed address before his next Parole Board appearance.
Given the seriousness of his offending and Mr Popo's somewhat "hesitant progression through his sentence", the board said Popo would require an extended reintegration period .
The board said there were no guarantees Popo would be released on parole before his sentence end date on April 12, 2017.
In 2001, Popo was charged with manslaughter after the high-profile shooting of 16-year-old Black Power prospect Wallace Whatuira on Waitangi Day.
He walked when a key witness refused to testify, despite having given evidence against the three Mongrel Mob men during depositions.
