The Department of Corrections has launched an investigation into a violent assault at Rimutaka Prison.
The attack has left a prisoner and staff member with serious injuries. The injured low security prisoner was being attacked by a group of other prisoners when the staff member stepped in.
The Department of Corrections says it was a 'spontaneous' assault, and one which is being taken seriously. It says it will not tolerate prisoners using violence against staff or other prisoners, and the prisoners involved will be held to account for their actions.
Police have been asked to investigate and criminal charges are expected to be laid.
