Pacific Islander and Māori people are overrepresented in the Australian criminal justice system. However, little research has examined relevant risk and protective factors and whether existing risk tools are appropriate for predicting risk and informing treatment for these populations. This paper used a qualitative, thematic analytical approach to canvass the opinions of Māori and Pacific Islander justice workers regarding risk and protective factors, the perceived suitability of the Level of Service/Risk Need Responsivity (LS/RNR) and best-practice approaches to engaging in a risk assessment interview with Pacific Islander and Māori people. Findings suggest that while many of the LS/RNR risk factors are likely to be relevant, there may be several culturally specific risk and protective factors that are not included in the LS/RNR. Consequently, the LS/RNR may not comprehensively assess the risks and needs of Pacific Islander and Māori people and may present some limitations in its capacity to inform treatment and management. Recommendations for practitioners and organizations and avenues for future research are discussed.
