List of dual place names in New Zealand

Official place names in New Zealand are usually determined by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa). In cases where there have been objections to a proposed name, a final decision is made by the Minister of Lands. A large number of dual names have been conferred not by the NZGB, but were negotiated as part of Treaty of Waitangi claims settlements and then enacted by Parliament. The 1998 Ngāi Tahu settlement alone established 87 dual names, including Aoraki / Mount Cook. Unofficial names are still recorded within the gazetteer, provided that they have "appeared in at least two publicly available authoritative publications or databases". In most cases, there is no functional difference between an official and unofficial name, with the NZGB expecting to standardise unofficial names as official by 2026. ==Orthography==

Originally, the board gazetted dual names in a form where the less commonly used name was in parentheses, e.g. Taylors Mistake (Te Onepoto). In the 1990s the system was changed to separating the names with a forward slash, viz., name1/name2, e.g. Aoraki/Mount Cook. Now, placing a space before and after the slash is encouraged, viz., name1 / name2. In 2021, the New Zealand Geographic Board voted to standardise the orthography of dual place names, and is in the process of updating names which use parentheses to the more common forward slash. The board now generally puts the Māori name first, but exceptions are sometimes made, for example when maritime safety is paramount (e.g. Baring Head / Ōrua-pouanui). ==List of official dual names==
