This report presents a study that focused specifically on the reasons leading to sex worker's first involvement in underage commercial sexual activities. The respondents had all been involved in prostitution since before 18 years of age. The research findings show that for the most part, 18-year-olds were guided into commercial sex by others, and that they had often received suggestions in relation to setting a price. The majority of the participants had attempted to leave prostitution; however, most were drawn back due to lack of money. Over half of the respondents to the questionnaire disclosed childhood sexual abuse. Compared with Pakeha respondents, a larger percentage of Maori, followed by Pacific peoples, disclosed sexual abuse as a child. The authors suggest that young people who have experienced a high rate of sexual abuse, and who are living apart from their parents, may be more vulnerable to commercial sexual activity exploitation.
