All of New Zealand's state-run jails will be made into "working prisons" by 2017 if National is re-elected, Corrections Minister Anne Tolley announced this afternoon.
Mrs Tolley also unveiled plans to introduce drug addiction treatment for ex-prisoners during a visit to Wiri Prison in South Auckland with Prime Minister John Key.
National signalled an increase in working prisons early last year, and confirmed today that the model would be expanded from three prisons to all 16 public prisons within four years.
Inmates would have structured 40-hour weeks which included work experience, skills training, education and drug and alcohol counselling or other rehabilitation programmes.
"The vast majority of prisoners don't want to be sitting around in their cells doing nothing," Mrs Tolley said.
