 No known pre-contact Māori name for New Zealand as a whole survives, although the Māori had several names for the North and South Islands, including "Te Ika-a-Māui" (the fish of Māui) for the North Island and "Te Waipounamu" (the waters of greenstone) and "Te Waka o Aoraki" (the canoe of Aoraki) for the South Island.Until the early 20th century, Māori also referred to the North Island as "Aotearoa" (commonly translated as 'long white cloud'); in modern Māori usage this has become the name for the whole country.Dutch explorer Abel Tasman was the first European to sight New Zealand, in 1642.
