This Kaupapa Māori study identified facilitators and barriers of codesigning a health promotion intervention with Māori communities. The study considered a specific Māori co-design framework, He Pikinga Waiora (HPW), which is a participatory approach to creating interventions emphasising community engagement, systems thinking and Kaupapa Māori. Study participants (n = 19) were stakeholders in the New Zealand health sector, and were interviewed using an in-depth, semi-structured protocol. Collaboration and community voice were found to be facilitators for co-designing health promotion interventions with Māori communities. Mismanaged expectations and research constraints were barriers. In terms of the HPW framework, facilitators included providing clear guidelines and being grounded in Māori perspectives, while barriers included limited concrete case studies, jargon and questions about sustainability. The study authors concluded that collaboration and inclusion of community voice supports the development of more effective co-design health promotion interventions within Māori communities, and
