Tectonic hazards have profoundly influenced Māori relationships with, and understandings of, the environment, with oral histories and ethnographic records referencing recurring encounters with volcanic eruptions, earthquakes, and tsunamis across Aotearoa-New Zealand. This research works alongside members of the Māori kin-group Ngāti Kuri to deliberate and compare active oral histories with two ethnographic records that potentially refer to ancestral experience with past tsunami(s) in the Kaikōura region. It applies an inductive-based methodology informed by “collaborative storytelling,” with the intent to appreciate the manner in which Ngāti Kuri interpret their past and present. The research affirms past catastrophic saltwater inundations and potential tectonic disturbances in the Kaikōura region. It also affirms that ethnographic records are not necessarily full or accurate accounts of historical events. The accounts presented here contribute to the reclaiming of Ngāti Kuri histories and point to new plural learning opportunities about coseismic tsunami hazard and history across the region.
