The aim of this study was to examine the extent and characteristics of the commercial sexual exploitation of children in New Zealand, and produce results that may be used to inform child welfare policy. Questionnaires from 280 respondents who work with children, such as counsellors, community workers, social workers and police, were used to gather information on aspects of child prostitution. The respondents felt that family background was a significant factor leading a child into prostitution: 64% said children they worked with had been sexually abused in the family, and 72% had been physically abused. The findings show that 82% of children were known to abuse drugs, and of these, 72% had been physically abused and 63% sexually abused. Strategies for eliminating the commercial exploitation of children are discussed, including more social and youth workers on the streets, and working to end violence and abuse in the family.
