This is the large greenish mussel so abundant in the North Island. In the South Island the common species is Mytilus edulis aoteanus, which is smaller and bluish-black. The largest and finest mussels are fished commercially from deep-water beds off Coromandel, Hauraki Gulf. Maori names for mussels are kuku and kutai.
