In Aotearoa New Zealand, rugby and rugby league are popular sporting codes, historically and particularly among males. In their 2023 annual reports, New Zealand Rugby reported 147,434 registered participants, while New Zealand Rugby League reported 28,180. Both institutions have also developed equity, diversity and inclusion strategies aimed at nurturing the participation and involvement of women and girls, as well as Māori and Pacific communities. However, while both codes have recorded an increase in female participation, there has been a gradual decline in male participation (Cully, 2023; Radio New Zealand, 2023; Wilson, 2022). This decline in sport participation has also been noted by (former) Principal Youth Court Judge Andrew Becroft, who found that young male offenders are often not involved in sport (Bruce, 2013; Sport NZ, 2018). This report summarises the findings of a study that examines sports attrition in relation to youth offending. In that study, the author (Clarke, 2012) examined the childhood and youth sporting experiences and illegal activities of five young men aged between 18 and 25 years old. The aim of this report is to provide insights into how these young men became involved in sport and why they dropped out, how they became involved in crime, and possible links between their sport participation and offending. Their experiences highlight several issues that can be addressed by parents/caregivers, clubs, sport administrators, coaches, community groups, sports organisations, and policymakers. In course of the study, six key observations were made. For these young men: 1. rugby and or rugby league were their primary and final sporting codes; 2. these sports were or had become ‘just a game’; 3. aggressive coaches diminished their enjoyment and commitment to sport; 4. their parents/caregivers were absent from their sporting lives; 5. their participation in sport and crime was simultaneous; and 6. the collision aspect of rugby and rugby league may have helped to facilitate their offending. In this document, the names of these young men have been replaced with aliases. To provide the reader with a richer and deeper understanding of the issues, the report features a number of their stories and reflections (edited for readability only). The research methods are briefly outlined in Appendix 1. Sources included in this report are listed in the References section.
