The broad-billed or coastal moa (Euryapteryx curtus) is an extinct species of moa. These moa lived in both the North and the South Islands of New Zealand, and on Stewart Island. Its habitat was in the lowlands (dunelands, forests, shrublands, and grasslands). It was a ratite and a member of the Struthioniformes Order. The Struthioniformes are flightless birds with a sternum without a keel. They also have a distinctive palate.
