Overcrowding is an issue for specific types of prison facilities


Several prisons are known to be overcrowded.

Budget of the prison service




The prison service outsources the management of the facilities to private companies, either partially or fully


The new Auckland South Correctional Facility (ASCF) in Wiri, opened in May 2015, is operated under a public-private partnership (PPP) by Serco and the consortium Secure Future.

Spotless Facility Services Limited are subcontracted by Serco New Zealand Limited for the provision of facilities management and asset management. According to the Department of Corrections, the contract “sets clear financial incentives to drive a reduction in re-offending. Incentive payments will only be attained if prisoners released from the facility re-offend 10% less than those from the public prison network. Rehabilitative techniques developed at Auckland South Corrections Facility will become the intellectual property of Corrections and can be put in place at other sites.1.

There are five categories of prisoners: remand accused, remand convicted, sentenced, voluntary segregated and youth. A parallel system takes into account security classification.

Prisons are usually divided by security level (maximum, high, low medium, low, minimum).

A security classification is given to prisoners within 14 days of sentencing and considers the supposed risk posed by the offender. Security classification is used to decide what unit a prisoner should be in.

15 prisons are destinated for male offenders and three for female offenders. There are also four Youth Justice Residences, for juvenile offenders.
