This commentary explores how systemic inequities and homelessness, particularly among Māori in New Zealand, can be addressed through a public health approach that integrates Indigenous models of health. It emphasises the importance of considering broader social determinants of health, such as housing, income, education, and access to healthcare, in the design and delivery of public health interventions. Utilising the Te Whare Tapa Whā framework, a Māori model of health, this commentary illustrates how culturally responsive and holistic approaches can enhance the effectiveness of public health programmes. Additionally, it discusses the potential for scaling this approach and its relevance to other marginalised populations and countries facing similar health disparities.
