A case study has described how one community used co-design and culturally-centred principles when developing a housing project to meet the health and social wellbeing needs of kaumātua. The study included interviews (n = 4), focus groups (4 groups; 16 participants in total) and survey questionnaires (n = 56) with kaumātua and organisation members. Enabling kaumātua to be connected to the marae was the primary purpose of the housing project, as part of a larger vision of developing intergenerational housing. Te Ao Māori was used in visioning, development of a collaborative team and funding, leadership, fit-for-purpose design, and tenancy management for the project.
