Seismic retrofitting of Māori wharenui in Aotearoa New Zealand.

Abstract

The design of Māori wharenui (meeting houses), refined over the last 180 years, has given rise to a distinctive typology that demonstrates an understanding of tectonic-narrative expression. It is a visual codex designed to be read. Set within the context of pre-disaster readiness, this current study investigated the resilience of Māori buildings and communities through a dual interpretation of seismic, regulatory and historical frameworks. The literature on Māori building technologies scarcely addresses matters of resilience and there is currently no formalized methodology to guide wharenui seismic retrofit practice. Through a macro level analysis of recently completed retrofit projects, this current study identified issues present in current practice. The resulting research presented a pathway for the future development of an approach (to inform methodologies) and strategy (to build capability) founded on the recognition of wharenui as a new category of building within building regulations. It is also recommended that research continues to develop alternative engineered solutions, expert knowledge bases and best practice guidelines.
