Fisher-Centric Methodology: Psychosocial Risks in Fishing Sector of Aotearoa NZ

ABSTRACT Objective Our paper focuses on the psychosocial risks faced by fishers in Aotearoa New Zealand, a sector with limited existing research on this topic. Using a culture-centered approach (CCA), we aimed to develop “voice infrastructure” to capture and present the voices of fishers, addressing the structural inequalities that can often leave fishers (like other marginalized groups) unheard. This paper focuses on the methodology of our pilot project that used a collaborative effort between academics, fishers, government, and non-government agencies, with the goal of understanding and mitigating the psychosocial risks within the commercial fishing industry. Method Phase 1 focused on building trust and personal relationships within the fishing community. We organized a day-long hui (meeting) in Nelson, a key fishing port, to facilitate open and flexible interactions. This setting allowed us to co-create the research design and instruments with the fishers, ensuring their perspectives were central to the study. The Copenhagen Psychosocial Risks Questionnaire (COPSOQ) was adapted in consultation with the fishers and piloted as survey (in phase 2) through a support network. Results Fishers acknowledged the need for wellbeing research and supported using the adapted COPSOQ. Data collection was inherently challenging in the fishing sector, due to the nature of the work with long shifts, limited communication, and minimal downtime. Trained mentors and counsellors administered the survey and ensured the process was fisher-centric and sensitive to their needs. Following data collection, a second hui (phase 3) was held to provide feedback to fishers about the survey results and review the process. This workshop aims to refine the methodology for potential national-scale implementation. The fishers emphasized the importance of sharing findings with them to ensure data accuracy before public reporting, aligning with the principles of CCA and co-creation of “voice infrastructures.” Conclusion Our study demonstrates the feasibility and importance of using a culture-centered approach in the fishing sector. By involving fishers in every step of the process, we aimed to create a more accurate and comprehensive understanding of the psychosocial risks they face, ultimately contributing to their wellbeing and the sustainability of the industry.
