ABSTRACT The Indigenisation of the architectural practice, research, and education in Australia and Aotearoa New Zealand has been an ongoing legacy from the early twentieth century until the present. This paper aims to begin mapping out significant agents, events, and processes of Indigeneity and Indigenising legacies when reviewing across the Trans-Tasman’s architectural education, research, and practice contexts. The study employs secondary data coupled with findings from action research and observations as architects, educators, and researchers positioned across the Trans-Tasman from each other. Trans-Indigeneity is an apt framework for this study because it centralises the experiences across Indigenous groups within globalised and colonial settler settings. The findings indicate an affinity that continues until the present between the closely connected circles of New Zealand and Australia’s Indigenous and non-Indigenous architectural researchers, educators, and practitioners at the forefront of Trans-Indigeneity. Across the Tasman, each Indigenous legacy has complemented and challenged the other towards common goals. The Trans-Tasman relationship, made possible through industry and academic gatherings and conferences, has assisted the Indigenisation and critical reflections of Indigeneity across the architectural profession in both locations.
