Unique offender and unique victim statistics

In July 2015 New Zealand Police and Statistics NZ started releasing statistics about unique offenders and unique victims. These collections complement the existing recorded crime offender statistics (RCOS) and recorded crime victims statistics (RCVS), allowing more insight into crime and victimisation. We will update these statistics monthly for the preceding 12-month period.

See Recorded crime offender statistics – tables and Recorded crime victims statistics – tables.

Recorded crime offender statistics

See New Zealand Police and Statistics NZ’s first release of statistics about recorded crime offenders. The recorded crime offender statistics (RCOS) complement the recorded crime victim statistics (RCVS). They include crimes that do not include a clear victim, such as drug offences. The RCOS tables and the RCVS tables replace the previously published twice-yearly crime statistics.

See Recorded crime offender statistics – tables.

Remand and sentenced prisoner statistics

The May 2015 release of 2014 calendar year and 2013/14 fiscal year remand and sentenced prisoners statistics is our first release of this collection. The Department of Corrections Offender Population / Volume Reports provide similar data to this release. 

We will update remand and sentenced prisoners statistics every six months.

See Remand and sentenced prisoners tables.
