Aotearoa (Māori: [aɔˈtɛaɾɔa]), originally used in reference to the North Island of New Zealand, is now the most widely known and accepted Māori name for the entire country. It is often pronounced /aʊtɪəˈroʊ.ə/ by English speakers, and is becoming widespread in the bilingual names of national organisations, such as the National Library of New Zealand / Te Puna Mātauranga o Aotearoa. Since the 1990s it has been the custom to sing New Zealand's national anthem, "God Defend New Zealand", in both Māori and English, exposing the term Aotearoa to a wider audience.
