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.

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

In the performance period Q1 2018/19, five prisons scored the grade of needs improvement; Rimutaka Prison, Auckland Prison, Christchurch Men’s Prison, Tongariro Prison and Manawatu Prison. These results reflect an increase in the number of incidents during this quarter. The table below contains the serious events that impact the Q1 2018/19 custodial performance result.

Rimutaka Prison has dropped three places from an exceptional grade in the previous quarter (Q4 2017/18). They experienced a prisoner escape from escort event, along with four serious prisoner on prisoner assaults. As a prisoner escape is seen to be a core gateway failure, Rimutaka Prison automatically obtained a needs improvement grade, regardless of any other event activity.

Auckland Prison continues to score a needs improvement grade in Q1 2018/19. In the latest quarter, the facility experienced one disorder event and 17 non‐serious assaults.

Christchurch Men’s Prison has dropped one place in Q1 2018/19, down from effective in the previous quarter. The Prison experienced four serious assaults (including one serious prisoner on staff assault). Further, there were 19 recorded non‐serious assaults and one wrongful release of a prisoner from custody.

Tongariro Prison has dropped three places in Q1 2018/19, down from exceptional in the previous quarter. They experienced one serious assault on a staff member and two non‐serious prisoner on prisoner assaults.

Manawatu Prison has dropped one place to needs improvement in Q1 2018/2019. The facility experienced three serious assaults and a number of non‐serious assaults.
