This research paper interrogates the extent to which indigenous, ethnic, and racial diversity is substantively integrated into climate justice discussions with a focus on New Zealand’s climate change adaptation policies. A qualitative research design is used, employing a documentary analysis and summative content analysis to scrutinise New Zealand climate change adaptation policies and their responsiveness to indigenous, ethnic and racial diversity within the ambit of climate justice. This study aims to measure the extent to which these policies promote inclusive and equitable climate adaptation outcomes. This study makes a significant contribution to the nuanced understanding of climate justice research, particularly regarding indigenous and ethnic minority communities. The study is expected to contribute to the existing knowledge base and inform the formulation of inclusive policies that integrate the diverse perspectives of these communities into climate adaptation and policy-making processes. The research findings highlight existing gaps and emphasise the importance of incorporating indigenous, ethnic, and racial diversity into policy development and implementation. The aim is to shape climate adaptation strategies that are representative of aware of insights from various communities in contemporary cities.
