Alex Aleti Seu, 36, has done 32 sessions with a counsellor while serving her six-years-nine-months sentence, and completed the Drug Treatment Programme at Auckland Prison.
But the Parole Board at a hearing this month could not allow release since the inmate had no approved address.
The Parole Board heard Seu had six previous convictions, including violence, but no prior sex crimes.
While in prison she had been made a mentor on a rehabilitation programme, had returned negative drug tests and was in the minimum-security unit.
“Ms Seu has positive reports on her conduct in the prison. The notes indicate that she gets on well with others in her programme and is respectful to staff,” panel convener Judge Geoffrey Ellis said.
“Ms Seu spoke briefly to the Board acknowledging her offending and indicating that through her psychological treatment she had come to terms with what she had done and the challenges facing her as she gets on with her life.”
The inmate told the board she wanted to go back to study when she was eventually released and perhaps pursue her interest in writing.
The board commended her for the work she had done and urged her to formulate a detailed safety plan before her next parole hearing in the coming weeks.
