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.
[7] The 1998 Ngāi Tahu settlement alone established 87 dual names, including Aoraki / Mount Cook.
In the 1990s the system was changed to separating the names with a forward slash, viz., name1/name2, e.g. Aoraki/Mount Cook.
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).
