Ōpōtiki comes from the name of a spring above Waiotahi Beach. It dates to a legend from the migration from Hawaiiki, about a chief, his brother and their two Tanahanaha fish pets known as O-Potiki-mai Tawhiti or "two pets from afar".
Reflecting the area’s importance for Māori, the main street of Ōpōtiki is decorated with the works of master carvers.
