December 2023

This case study explores in depth the issues surrounding climate adaptation and managed relocation within the coastal area from Ōmana to Umupuia, including the coastal Auckland suburb of Maraetai. The case study presents the findings from a mix of desktop and empirical analysis. Desktop material included local and central government documents, independent reports, historical and archival articles and academic literature. The empirical component included interviews with 56 residents and non-residents in the case study area and engagement with Ngāi Tai ki Tāmaki.

The case study explores the social, cultural, economic and historical contexts, the nature of the risks being faced, current responses to them and how residents, mana whenua and others perceive the risks and wish to respond to them. It also draws out specific lessons from the case study that can inform managed retreat policy.
