However, interventions designed for the general population tend to be less effective for M─ori communities and may contribute to increased health inequities. We describe the integration of co-design and kaupapa M─ori research approaches to design a mobile-phone delivered (mHealth) healthy lifestyle app that supports the health aspirations of M─ori communities. The co-design approach empowered our communities to take an active role in the research. They described a holistic vision of health centred on family well-being and maintaining connections to people and place. Our resultant prototype app, [email protected]@, includes content that would not have been readily envisaged by academic researchers used to adapting international research on behaviour change techniques to develop health interventions. We argue that this research approach should be considered best practice for developing health interventions targeting M─ori communities in future %K M─ori health %K indigenous health %K mHealth %K eHealth %K participatory research %K co-design %U https://journals.sagepub.com/doi/full/10.1177/1177180117753169
