The New Zealand dollar (sign: $; code: NZD) (Maori: Tara o Aotearoa) is the currency and legal tender of New Zealand, the Cook Islands, Niue, the Ross Dependency, Tokelau, and a British territory, the Pitcairn Islands. Within New Zealand, it is almost always abbreviated with the dollar sign ($), with "NZ $" sometimes used to distinguish it from other dollar-denominated currencies.
