1 Dollar - Elizabeth II 4th Portrait, Tev Wahine

Tev Wahine — "woman's sea" in te reo Māori — refers specifically to the deceptively calm surface conditions that can precede dangerous swells on New Zealand's coastal waters. The Reserve Bank's decision to draw on traditional Māori environmental knowledge for a bullion-adjacent commemorative reflected a broader shift in how New Zealand institutions were engaging with indigenous concepts in the late 2010s, accelerated by the country's ongoing work toward fuller implementation of Treaty of Waitangi obligations.

The 2 troy ounce format places this squarely in the collector-bullion category rather than genuine circulation issue.
