At present, New Zealand does not have a data source dedicated to identifying and recording all forms of family violence in our communities. Researchers have conducted a number of population-based and smaller surveys that identify how many people have experienced family violence. However, there are no official family violence statistics collected on a regular basis. As such, policy makers, practitioners and researchers are required to make do with data that is collected for administrative purposes by government and non-government agencies. It is important to remember that:
"... although there are some useful administrative data sets in New Zealand, none could currently be considered a reliable source of data for monitoring trends in family violence in the community over time." (Gulliver & Fanslow, 2013, p.78).
These papers describe the difficulties associated with the collection and collation of family and sexual violence statistics at a national level:
