At the very end of the 19th century a Kāi Tahu man named William Timaru Joss (1844–1895), a Stewart Island whaler and captain of the mailboat "Ulva", was a member of the first confirmed landing party of the "Antarctic" on the continent of Antarctica at Cape Adare, along with Captain Kristensen, Bull, Borchgrevink, and Tunzelmann in January 1895, making Joss the first known Māori to get so close to the continent. Timaru William Joss (1905–1955), William Timaru's grandson, joined Admiral Richard E. Byrd's expedition to Antarctica in 1935.
