This book provides an overview of Pacific-Indigenous knowledge as insights of Oceanic citizen-science to inform culturally-safe practice for psychology. It profiles contemporary Pacific needs in areas of crisis such as family violence, education disparities and health inequities, and points to ancient Pacific-indigenous knowledges as tools of healing for global diasporic communities in need. The historical evolution of psychology's knowledge base and practice illustrates a fundamental crisis in the method of producing knowledge for psychology - the absence of Pacific-indigenous cultural knowledge. It suggests more effective research methodologies grounded in Pacific-Indigenous epistemologies and ontologies for psychology and overall community capability. It fosters practice perspectives and strategies based on NIU-psychology (New Indigenous Understandings) for innovative solutions to modern-day crises of humanity.
