We look at interpersonal violence in two ways:
When victims knew who had committed the offence, the NZCASS asked what their relationship was to the offender at the time of the offence. From this information we can look at victimisation by different types of relationship:
In the 2014 NZCASS, ‘violent interpersonal offences’ included three main offence groupings:
While there were no changes between 2005 and 2008, all violent interpersonal offence measures fell between 2008 and 2013:
While the number of violent interpersonal offences fell between 2008 and 2013, the percentage of violent interpersonal offences, compared to non-violent crime, increased to 67% in 2013 (up from 59% in 2008).
When we looked at the number of violent interpersonal offences by the victim’s relationship to the offender in 2013, we found that:
We also looked at the percentage of adults who were victims of one or more violent interpersonal offences in 2013 by the victim’s relationship to the offender. See the diagram below for the figures.
A. Rounds to 4% from unrounded numbers.
You can’t add together the different relationship groups in the diagram because:
As well as looking at the victim’s relationship to the offender, we also looked at the type of interpersonal violence they experienced.
When looking at the different types of violent interpersonal offences experienced iIn 2013, we found:
We also looked at the percentage of people who experienced more than one type of these violent interpersonal offences, and found that in 2013 1% of adults experienced all three types of interpersonal violence (threats and damage, physical, and sexual).
We analysed the different offender relationships within the three types of violent interpersonal offences in 2013. We found that:
When looking at interpersonal violence committed by intimate partners, we found that women (6%) were more likely than men (4%) to be the victim of a violent interpersonal offence by an intimate partner in 2013.
We looked at whether men and women experienced intimate partner violence differently. We found that in 2013:
In 2013, 23% of violent interpersonal offences committed by a family member were reported to Police.
According to victims of interpersonal violence, just under a quarter (24%) of all violent interpersonal offences were reported to Police in 2013, with no statistically significant change from 2005 or 2008.
When we looked at the reporting of interpersonal violence by the victim’s relationship to the offender (intimate partners, family excluding intimate partners, people known excluding family, or strangers), we found there were no statistically significant differences in reporting to Police for any of the relationship groups in 2013. There were also no statistically significant changes over time.
Where a victim had contact with the offender (or offenders), we asked whether the offender had a weapon or something they used, or threatened to use, as a weapon.
In 2013, a weapon was used in 18% of violent interpersonal offences, with no statistically significant change from 2008.
When a victim had contact with the offender or offenders, they were asked ‘as far as you know, at the time it happened, was the person who did it affected at all by alcohol?’
In 2013, the offender or offenders (but not the victim) had been drinking in 18% of violent interpersonal offences, while both the offender(s) and the victim had been drinking in 20% of violent interpersonal offences.
Victims were also asked: As far as you know, at the time it happened, was the person who did it affected at all by drugs?
In 2013, offenders were thought to be affected by drugs in 26% of violent interpersonal offences, with no statistically significant change from 2008.
There was a large percentage of ‘don’t know’ responses for this particular question (21%) because many people said that unless they had witnessed the drug-taking personally they were not sure they could recognise the symptoms.
