The New Zealand dollar (Māori: tāra o Aotearoa; sign: $; code: NZD) is the official currency and legal tender of New Zealand including 2 freely associated states of New Zealand (Cook Islands and Niue), 2 dependent territories of New Zealand (Ross Dependency and Tokelau) and a British territory, the Pitcairn Islands. Within New Zealand, it is almost always abbreviated with the dollar sign ($). The abbreviations "$NZ" or "NZ$" are used (outside New Zealand) when necessary to distinguish it from other dollar-denominated currencies. The New Zealand dollar was introduced in 1967. It is subdivided into 100 cents. Altogether it has five coins and five banknotes with the smallest being the 10-cent coin; smaller denominations have been discontinued due to inflation and production costs. In the context of currency trading, the New Zealand dollar is sometimes informally called the "Kiwi" or "Kiwi dollar", since the flightless bird, the kiwi, is depicted on its one-dollar coin. It is the tenth most traded currency in the world, representing 2.1% of global foreign exchange market daily turnover in 2019.
