Haumuri Bluff (also known as Amuri Bluff) is a headland on the coast of New Zealand's South Island on the south side of Piripaua (Spyglass Point), located several kilometres south of Oaro. It has been a major palaeontological site since the mid-19th century,[1] and has lent its name to the Haumurian stage in the New Zealand geologic time scale. The bluff has also been the site of numerous shipwrecks.
