Family violence victimisations
Family violence victimisations are acts intended to cause injury, sexual assault and related offences and abduction, harassment and other related offences against a person where the relationship of the offender to the victim is family member (including ex-partner) . New Zealand has among the highest rates of recorded family violence in the developed world  and there are likely many more people affected by family violence than are captured by family violence indicators, as many instances of family violence go unreported .
Family violence is linked to a series of negative health and wellbeing outcomes both in the short and long term. For example, children who witness violence between parents or who are victims of parents’ violence are at higher risk of experiencing behavioural problems, or bullying other children, or achieving poor school performance . Domestic violence also brings about high public costs for victim support, medical care, mental health services, police, and other losses of productivity .
This indicator presents the number of victimisations for acts intended to cause injury, sexual assault and related offences and abduction, harassment and other related offences against a person where the relationship of the offender to the victim is family member (including ex-partner), monthly, in the Canterbury Metro Area (includes Christchurch City and Lyttelton; excludes Akaroa, Lincoln, Rolleston, Kaiapoi).
The figure shows that there has been little change in the recorded number of victimisations for family violence in Canterbury over the last three years (the extent of the time-series data available under the current crime reporting system). The number of victimisations has fluctuated, and ranged from 36 to 80 per month over the period shown. Trend analysis is not available for these data. The figure also shows that the number of victimisations for acts of family violence is somewhat higher during the summer months; and this is likely to be related to both social and physical environmental factors (related to temperature and changes to patterns of routine activities) [25,29].
