Prison staff at a number of the country's jails look set to lose their jobs when a new privately run facility at Wiri near Auckland replaces several older jails.
Prime Minister John Key confirmed this morning that a number of older prisons would close, but stopped short of saying which ones or how many.
"We're going through the process of talking to the unions that are involved.''
Mr Key told Newstalk ZB that the financial impact the closures would have on local communities had been considered, but that overall it was in the best interests of the justice system not to keep them going.
"They required a lot of ongoing maintenance, so actually they wouldn't be great facilities for the prisoners and staff who work in them,'' Mr Key said.
