As per our Terms of Use, all PayPal transactions are charged in USD, even if you are located in New Zealand.
While PayPal is a valid payment option, you should be aware that in addition to conversion fees, PayPal adds a further transaction fee. These fees are not set or received by New Zealand Mint.
If you wish to pay in your own currency, we recommend using a standard credit card at checkout. This option can be found on the Continue to Payment page after submitting your shipping details.
