Farewell Spit (Māori: Onetahua) is a narrow sand spit at the northern end of the Golden Bay, South Island of New Zealand. It runs eastwards from Cape Farewell, the island's northernmost point. Farewell Spit is a legally protected Nature Reserve and is designated as a Ramsar wetland site and an East Asian–Australasian Flyway Shorebird Network site. The spit is administered by the New Zealand Department of Conservation as a seabird and wild life reserve. Apart from a small area at the base of the spit, it is closed to the public except through organised tours.
