10 Dollars - Charles III Fuller Portrait - Cave Taniwha, Gold Proof

The taniwha of Māori tradition occupies a genuinely ambiguous place in the culture — neither straightforwardly monster nor guardian, but a being whose nature shifts depending on the relationship between it and the people of a given waterway or cave. The cave-dwelling variant specifically is associated with subterranean passages, sinkholes, and the kind of geological feature that early Māori navigators and settlers would have encountered and mapped through oral tradition rather than cartography.

The "fuller portrait" designation distinguishes this issue from the transitional effigy used on New Zealand coinage immediately following Elizabeth II's death — Charles III's definitive portrait, sculpted by Martin Jennings, was formally approved for Commonwealth coinage in 2023.
