The New Zealand coastline is susceptible to tsunami hazards from both regional and trans-pacific sources. With a coastal population only expected to increase over the coming decades, the risk associated with tsunami activity has seen a similar increase. The historical record for tsunami in New Zealand only extends back a mere 200 years and is too short to capture the range of tsunami that could potentially affect the coastline. In efforts to better prepare against future events, various paleotsunami studies have been undertaken across the New Zealand coastline to study tsunami that occurred before the historical record began. Despite this, a lack of well-preserved indicators within deposits has led to a scarcity in high-resolution evidence that has been well dated. This study utilises the preservation capabilities of the Omaha Beach barrier system that has built seaward (prograded) over the past ~ 6500 years, in order to identify viable evidence for a paleotsunami deposit as well as po
