Another attempted breakout occurred this week as two prisoners, who recently escaped from another jail, tried to break out of Paremoremo by punching holes in their cells.
Jesse Lee Ibell, 24, and Wayne Holmes, 23, escaped from Waikeria Prison near Te Awamutu last month.
"It was regarded as an escape attempt. The general manager of prisons came from Wellington to inspect it," said the source.
The Corrections Department refused to speak about either of the attempted prison escapes.
General Manager Prison Services Jeanette Burns said there was zero tolerance of disruption to the running of prisons.
"All incidents of disruption or deliberate damage are fully investigated and are likely to lead to the prisoners involved facing internal disciplinary action and possibly criminal charges."
Burns said that ensuring public safety was the department's priority and incidents of prisoner disorder and disruption were contained and managed within the prison.
