Seen throughout New Zealand. They usually breed August-January inland in the South Island, mainly east of the Southern Alps on riverbeds and farmland, in sand scrapes on farmland or gravel banks in braided rivers. They are also known to breed on high country grasslands and in coastal areas adjacent to estuaries and lagoons where they are also found during the non-breeding season (distribution map).

Description 

One of two species of oystercatcher in New Zealand, the endemic South Island pied oystercatcher (Haematopus finschi) is also known as the New Zealand pied oystercatcher, Finsch’s oystercatcher, tōrea, torea (Māori), and SIPO. In coastal areas they are commonly seen feeding in bivalves (hence their name), small crustaceans, cnidarians (jellyfish) and fish. Further inlands they have been seen feeding on worms and small beetles.
