A third of Aotearoa New Zealand’s increasingly ageing population resides in Tāmaki Makaurau Auckland. This most populous cosmopolitan urban area in the country is also home to the largest Polynesian population of any global city. Sprawling across a North Island isthmus inclusive of Hauraki Gulf islands, 70% of the city region is rural, whilst almost 90% of the ethnically diverse residents live in urban areas. Members of Auckland Council’s Seniors Advisory Panel (SAP) advocated for, and in 2018 secured unanimous support from the governing body to resource an Age-friendly City (AFC) Project. This case study inquiry applied bricolage methodology to provide diverse contextual perspectives of this unique Polynesian setting, prior to exploring interview narratives of three SAP members who served two consecutive terms (six years) as AFC advocates. Weaving insights gleaned from their interview transcripts responding to relational leadership prompts about their age-friendly advocacy with the findings from the council’s AFC Community Engagement report highlighted the achievements and challenges of the evolving AFC Project. Service-learning recommendations include co-developing: (1) A sustainable co-governance framework for an independent steering group that embodies the values and principles of Te Tiriti o Waitangi to enable empowered active ageing for all residents; (2) A succession plan that enables the timely transfer of knowledge and skills to empower incoming SAP members.
