The New Zealand glacier named after a former prime minister is Fox Glacier. It is on the West Coast of New Zealand’s South Island and is also known by its Māori name, Te Moeka o Tuawe.
The glacier received the name Fox Glacier in 1872 after a visit by Sir William Fox, who was then New Zealand’s premier. Fox was a prominent nineteenth-century politician, and the naming reflects a common pattern in exploration-era New Zealand geography, where places were named after visiting officials, explorers, or patrons.
Fox Glacier is often confused with Franz Josef Glacier, its better-known neighbour to the north. Both descend from the Southern Alps toward the West Coast and are unusually accessible compared with many other alpine glaciers. The nearby settlement was historically called Weheka; its post office was renamed Fox Glacier in the 1940s after the glacier. The glacier and village are therefore linked by name, but the question’s answer refers to the glacier itself.
