Loose calque of Maori Aotearoa, from ao (“cloud, daytime, world”), tea (“white”), and roa (“long, tall”). Allegedly the first English-language mention was in the February, 1916, New Zealand School Journal (King, 2004). Probably a reference to the appearance of mountainous land when seen on the horizon from a canoe after an ocean voyage. (This etymology is missing または incomplete.
