Policing the First World War: slygrogging, sex and sedition

Year: 2015

Agency: NZ Police

Author: Elizabeth Plumridge, Rowan Carroll, New Zealand Police Museum

In the 1914-18 war, civilian society in New Zealand had to turn itself into a militarised society. The population of New Zealand at the beginning of the Great War was a little over one million, of that number 100,000 were eligible to serve. Persuading those eligible to join up did not happen ‘naturally’: it required coercion on a grand scale. Throughout WWI New Zealand Police were the invisible military machine.
The New Zealand Police Museum have researched and written seven essays that explain the role of New Zealand Police during WWI, Please feel free to read and share but don’t forget to reference the source.

Sex Offenders

Year: 2015

Agency: Corrections

Around 500 offenders are sentenced to imprisonment each year for sex offences, which is only about 7 percent of total receptions. However, their sentences tend to be significantly longer than the average. Consequently, they spend longer periods in prison, and thus comprise a significant proportion of the prison population, a proportion which is slowly but steadily increasing. For this reason, as well as the fact their crimes are very serious, and the risks to public safety of any subsequent re-offending, they are an important focus for rehabilitation as well as post-release management.

Pacific Offenders

Year: 2015

Agency: Corrections

Offenders of Pacific ethnicity make up 12 percent of all prisoners, and a slightly lower proportion of the population of offenders serving community sentences (10%). This report provides a statistical breakdown of trends in the Pacific offender population in recent years, in relation to gender, offence type, age and other key characteristics.

Young Offenders

Year: 2015

Agency: Corrections

While offenders under the age of 20 account for a small proportion of offenders serving sentences administered by Corrections, they are an important target group. Effective intervention with young offenders has the potential to have a substantial impact on re-offending, shortening what might otherwise be lengthy criminal trajectories.

Evaluation of the Defendant Centred Courtroom Pilot

Year: 2014

Author: Michelle Lennan and Sue Carswell

The Defendant Centred Courtroom (DCC) pilot trialed a reconfigured District Court courtroom where defendants who are not in custody sit or stand beside their counsel at the front of the court instead of standing in the dock. It is anticipated that placing the defendant at the centre of the courtroom will make the court process more understandable and accessible for defendants. It is expected that increasing understanding and engagement will culminate in a reduction in reoffending and an increase in sentence compliance among participating defendants.

Evaluation of the 2013/14 Safer Summer Road Safety Campaign

Year: 2014

Agency: NZ Police

Author: NZ Police

The 10km/h speed enforcement threshold has been reduced to 4km/h during official holiday periods in New Zealand since Queen’s Birthday weekend 2010. The 2013/14 Safer Summer road safety campaign was the first time the speed enforcement threshold reduction had been extended beyond official holiday periods to a full two month period.

The campaign was carried out by Police from 1 December 2013 to 31 January 2014, and supported by the wider road safety sector. It involved a well-publicised reduced speed enforcement threshold, combined with intensified and highly visible speed enforcement.

The final report evaluates the effects of the campaign on speeding and crashes.

Offenders on Indeterminate Sentences

Year: 2014

Agency: Corrections

Author: Corrections

Prisoners serving sentences of Life Imprisonment and Preventive Detention form a distinct sub-set of the prisoner population.  The following pages provide information about recent trends involving these offenders.  As will become apparent, numbers of prisoners serving indeterminate sentences have been growing steadily for several decades.

It is hoped that this analysis will improve understanding of this sub-group, and potentially stimulate improvements in the management of such offenders, both while in prison, and after their eventual release.

Family Violence Offenders

Year: 2014

Agency: Corrections

Author: Corrections

The term “family violence” covers a broad range of violent and controlling behaviours suffered by persons with whom a perpetrator shares (or has shared) an intimate, family or family-like relationship . Family violence can be physical, sexual and/or psychological in nature, actual or threatened, and may involve fear, intimidation and emotional deprivation. Family violence also includes behaviours that depart from a reasonable standard of care for children or vulnerable persons .

This paper sets out to describe the sub-group of offenders managed by the Department who are sentenced for family violence offences.

In the Corrections context, offences most commonly associated with family violence include assaults and injuring, sexual assault, threats and intimidation, property damage, and breaches of orders. In a small number of cases family violence involves homicide offences (Murder, Manslaughter).

Analysis of family violence offending is complex because of the range of offences involved, and because available data do not always clearly convey whether an offence relates specifically to family violence.  The data used for this analysis therefore comes from two sources; NZ Police data enables the linking of sentences to family violence offences, although this data is somewhat limited, spanning only the period January 2011 to December 2013; secondly, the Department’s own sentencing data includes certain codes that specify some offences as family violence-related.

Where definitive data is not available, data points have been estimated by calculating the rate of offenders starting family violence offences in 2011-2013 and extrapolating against the total number of unique offenders starting sentences each year.  These have been depicted as dotted lines on graphs.

Secondly, it is common for offenders to be sentenced on a number of different offences; in some cases, the mix of offences includes family violence offences, but these offences may or may not be the most serious in the mix. In this report, the term “family violence aggregate sentence” is used to refer to a sentence where any (one or more) of the offences relate to family violence.

Offender Population Report

Justice Sector Seriousness Score (2012 revision): FAQs

Year: 2013

Agency: Ministry of Justice

Author: Charles Sullivan and Ong Su-Wuen

Seriousness scores are a way of quantifying the relative seriousness of offences based on the sentences imposed for each offence. Users need to be aware that sentences are an imperfect proxy for seriousness because they take into account factors other than seriousness of the offence under consideration (eg, previous criminal history of the offender).
Uses for seriousness scores across the justice sector include:

-Helping to determine the ‘most serious offence’ for an offender or case
-Department of Corrections risk of reimprisonment tool RoC*RoI
-Monitoring effectiveness of interventions (eg, to check whether seriousness of youth re-offending reduces after interventions).

Formative Evaluation of the Mothers with Babies Units

Year: 2013

Agency: Corrections

Author: OTS ConsultingMomentum Research & Evaluation Limited

Housing very young children in a prison setting is a challenging and very unusual situation for Corrections staff. The Department sought an independent evaluation of its management of these special units, to provide assurance that everything possible was being done to ensure that the children were safe, that the mothers’ and the babies’ best interests were being protected, and that the children’s developmental needs were being met.

The report summarised published research on mother with baby programmes in prisons, which consistently shows that mother with baby units do support development of secure attachment in the child and increased parenting skills and maternal sensitivity in the mothers; research also provides some evidence that mothers with baby units can help reduce re-offending.

The overall conclusions were that the units have continued to develop, that positive advances have been made, and an underlying “best interests of the child” approach to decision-making was evident.Issues noted as requiring further attention included having a mix of both male and female staff at MWB units, having dedicated unit staff, the frequency of parenting programmes, instituting alternative caregiver assessments, and shortening wait times for approval to enter the units. Also recommended were further training of new staff, and improved national co-ordination of the units and the ways in which the mothers with babies policy is managed.
