"He explained his ongoing association by saying that they are his safety network in prison. He acknowledged that this association rolls over into the community," the report says.
The Killer Beez are a street gang that has been operating since the early 2000s, having formed in South Auckland. Its president, Josh Masters, is serving a lengthy prison sentence for drug-related offending.
O'Neill told the board he had plans to better himself after prison and hoped to become a gib-stopper by getting a certificate. A representative from the prison said O'Neill was "generally pretty good" in jail.
O'Neill was declined parole at that hearing in July but was released when his sentence ended two months later, on September 2. A psychological report noted O'Neill had a "high risk of further violent offending as he is yet to address his propensity for violence", the board said in its report.
O'Neill's funeral was held in the coastal Hauraki district town of Waihi, where police were on standby in case of any trouble. Local media reported at the time that police didn't expect any issues but an "increase in gang related activity" was expected.
