Coins of The New Zealand Dollar - Use of Other Countries' Coins

Use of Other Countries' Coins

Due to regional travel and the fact that many other former British colonies around the world use coinage systems with British-derived origins of sizing and weight, many Fijian, Samoan, Singaporean, South African, and especially Australian coins had been in daily circulation in New Zealand despite not being official legal tender. It is of note that the United Kingdom itself does not use these sizes of coins any more, and there has been the odd case of foreign coins appearing in a customer's change. The consistently similar but not significantly higher value of the Australian currency and the obverse side of Australian coins being almost the same as New Zealand coins also didn't discourage this practice, with millions of 5, 10, and 20 cent Australian coins having been used in New Zealand in an identical manner to their true counterparts. These coins could circulate for long periods without being recognised. The coinage size and material changeover (see below) of 31 July to 31 October 2006 means these foreign coins can no longer be accepted interchangeably, though the new 10 cent coin strongly resembles the British one penny coin in size, weight and appearance and the unchanged one dollar coin remains very similar to the Fijian counterpart. There is also occasional confusion between the New Zealand one dollar coin and the Australian two dollar coin, and similarly between the New Zealand two dollar coin and Australian one dollar coin, on account of the coins' similar sizes and weights.
