5 Dollars - Elizabeth II 4th Portrait, Chatham Island Crested Penguin

New Zealand's collector coinage program has leaned heavily on endemic wildlife since the 1990s, but the Chatham Island Tawaki — found only on the remote Chatham Islands roughly 800 kilometers east of the South Island — rarely makes the shortlist. The subspecies was formally separated from the Fiordland crested penguin only through molecular work published in the 2000s, giving it a taxonomic identity recent enough that earlier issues would have simply called it something else.

Pad printing on .999 silver allows color application without enamel cloisonné work, a production method New Zealand's program adopted to keep unit costs manageable on limited-run wildlife issues.
