Tokelau, known previously as the Tokelau Islands, is a dependent territory of New Zealand in the southern Pacific Ocean. It uses the New Zealand Dollar as circulation currency, but has been issuing a variety if non-circulating coins since 1978. These are denominated in "Tala" (the local word for Dollar) and cents.
Five troy ounces of gold is a large format which is denominated as Five Hundred Dollars. These coins are considered Non-Circulating Legal Tender (NCLT) and not bullion, since they are issued with relatively low mintage and at prices with a high premium over the intrinsic value of their metal content.
