Gold Calculator – New Zealand

This calculator is pre-set for New Zealand: the currency is New Zealand Dollar (NZD), the weight units are the ones local buyers actually use — 1 Troy Oz, 1 Gram, 1 Kilogram— and the rate is today's gold-api.com x Exchange Rate API figure, as of 14 Nov 2026. Enter the weight of your gold, pick its purity, and the calculator shows the metal value instantly. You can then add making charges and any extra cost to see the full price a jeweller would quote.

Worked example: 1 troy ounce of 22K gold weighs 31.1grams. At today's 22K rate of NZ$ 207.30 per gram, that gold is worth NZ$ 6,447.75 before making charges. For comparison, 24K gold is NZ$ 7,033.43 per troy ounce and 22K is NZ$ 6,447.75 per troy ounce today. The same calculation works for any weight — the calculator converts your unit to grams, applies the purity factor, and multiplies by the rate.

Making charges vary by jeweller — there is no single standard rate, so adjust the slider or fixed amount to the quote you were given. Taxes and hallmarking fees, where they apply, are also separate from the headline rate; use the additional-cost field to include them. The rate on this page is refreshed twice daily and always shows its as-of date, so you can see exactly how current the figure is.
