 The practice of giving certain New Zealand places dual names began in the 1920s, but dual names have become much more common in the 1990s and 2000s, in part due to Treaty of Waitangi settlements.Many places have names with a long heritage in each culture.For instance, one settlement saw Cloudy Bay, given this name by Captain Cook in 1770, renamed Te Koko-o-Kupe / Cloudy Bay, with the Māori name recalling the early explorer Kupe scooping up oysters from the bay.
