The current study is intended to assist the Department of Corrections in meeting its strategic objectives regarding the management and rehabilitation of offenders. It provides straightforward data on the characteristics of sex offenders and their recidivism rates. The data presented here are based on the “recidivism index” (RI) methodology used in the Department of Corrections’ annual reporting of reconviction. This method quantifies the rate of reconviction and re-imprisonment for specified sub-groups of offenders, over follow-up periods of defined length, after release from a custodial sentence, or following commencement of a community sentence or order. Conviction and sentencing data is obtained from the Ministry of Justice’s Case Management System (CMS) database.
