The NZD/USD pair, also called the “Kiwi”, tells the trader how many US dollars (the quote currency) are needed to purchase one New Zealand dollar (the base currency). This currency pair is also known as the "Kiwi". Together with the Australian Dollar and the Canadian Dollar, the NZD is a commodity currency, that is a currency whose country's exports are largely comprised of raw materials (precious metals, oil, agriculture, etc.).
Along with the Australian Dollar, the NZD has been for many years a traditional vehicle for carry traders, which has made this currency also very sensitive to changes in interest rates.
