A Wellington woman who has spent the past 15 years in jail for stabbing to death her friend who dobbed her into police is to be released from prison.
Melissa Anne Wepa, 38, was sentenced to life imprisonment for the murder of Porirua woman Caroline Gardiner in 1997.
At the time of her trial the High Court at Wellington was told Wepa stabbed Ms Gardiner 50 times for telling police about Wepa's involvement in a burglary.
Wepa, who met Ms Gardiner in the early 90s while they were both in Wellington's Arohata Prison, initially pleaded not guilty to the murder but changed her plea to guilty several days into the trial.
Nine months into her life sentence, Wepa - who had affiliations to the Mongrel Mob and Deadly F***ing Bitches gangs - was also charged after nearly biting off another inmate's nipple during a fight.
