Prison Performance Tables

The Prison Performance Tables provide a quarterly grading of the performance of all prisons within the Corrections network. A number of factors are used in this analysis, and results are weighted to account for the particular composition of prisoners and facilities at each site.

The Custodial Performance Table includes results for core security and internal procedures:

  • Core security – a gateway test for certain incidents including breakout escapes, escapes from escort, and significant disorder events. These incidents are considered unacceptable regardless of the number of prisoners or any other factors.
  • Internal procedures – a score assigned to each prison based on the number of core security events and the level of other incidents, including assaults on staff and prisoners, justified complaints, and the percentage of positive general random drugs tests.
  • In addition to incident reporting, the results of a range of periodic reviews and investigations are considered when grading each prison.  If the findings of these reviews and investigations do not reflect the calculated custodial performance result for a prison the Department of Corrections may downgrade that prison.

The Industry, Treatment and Learning Performance Table reflects performance against a number of key performance indicators measuring the delivery of programmes that provide offenders with the skills and opportunities that they need to take greater control of their lives. The effectiveness of these programmes is assessed annually and the results of the latest assessment were published in the 2015/16 Annual Report (see page 50).

On the basis of results in the Custodial Performance Table and the Industry, Treatment and Learning Performance Table, each prison is graded as exceptional, exceeding, effective, or needs improvement.

Custodial Performance Results

The custodial performance results in Q2 2016/17 reflect an increase in the number of incidents from the previous quarter. The table below contains the serious events that impact the Q2 2016/17 custodial performance result.

There was one core security event in the quarter; an escape from medical escort that occurred in November involving a prisoner from Christchurch Men’s Prison, the offender was captured shortly afterwards.  This event means that Christchurch Men’s Prison automatically records a grade of needs improvement, irrespective of the internal procedures score.

Christchurch Men’s Prison and Auckland Prison both experienced events in which multiple staff members were seriously assaulted by prisoners.  These incidents are heavily weighted in the custodial performance tables. The incidents that occurred in Q2 will continue to impact results for a further three quarters and mean that both prisons are likely to remain in needs improvement in Q3.

At Q2 the number of prisons in needs improvement increases to three (Q1: two) as Christchurch Men’s Prison drops from effective. Hawkes Bay Regional Prison and Auckland Prison were both in needs improvement at Q1 and remain there in Q2.
