 (pronounced  in Māori and  in English; often translated as 'land of the long white cloud') is the current Māori name for New Zealand. It is unknown whether Māori had a name for the whole country before the arrival of Europeans;  originally referred to just the North Island. Māori had several traditional names for the two main islands, including  ('the fish of ') for the North Island and  ('the waters of greenstone') or  ('the canoe of ') for the South Island. Early European maps labelled the islands North (North Island), Middle (South Island) and South (Stewart Island / ). In 1830, mapmakers began to use "North" and "South" on their maps to distinguish the two largest islands, and by 1907 this was the accepted norm. The New Zealand Geographic Board discovered in 2009 that the names of the North Island and South Island had never been formalised, and names and alternative names were formalised in 2013. This set the names as North Island or , and South Island or . For each island, either its English or Māori name can be used, or both can be used together. Similarly the Māori and English names for the whole country are sometimes used together (Aotearoa New Zealand); however, this has no official recognition.
