With the Multi Currency plugin you can add additional currency options, setting the currencies to a fixed conversion rate or using live rates.
With fixed currency conversions, prices will be offered to customers at your fixed exchange rates. If you provide this option, you need to have compatible payment options for these currencies. Paypal will support about 15 currencies, many other payment gateways only support 1 or 2 currencies.
That rate will be subject to change, do a search on google for "1 NZD IN USD" and copy the result. Increase the amount by about 2%-5% to account for currency fluctuations and FX margin costs.
Live exchange rates are only available on some currencies, you should review these from time to time to ensure you are happy with them, or set your own default.
If we have a live price, we will override your price daily, where you have opted in for live pricing.
Our live prices are based on "mid rates". Mid rates are the middle fx rate, between a buy/sell rate. You will find that Paypal and other payment options will use different rates that us. The merchant will likely lose.
