Te puka a Te waka

The early Maori name for the Island, Te puka a Te waka a Maui (the anchor of the Maui canoe)
refers to the story of Maui's discovery of NZ, he used the South Island as a Waka (canoe) to fish up the North Island while Stewart Island /Rakiura anchored his canoe. The chain sculpture at Lee Bay, which marks the entrance to Rakiura National park is in recognition of this legend.

Rakiura is today a commonly translated as land of the glowing skies possible in reference to the vibrant sunrises lingering sunset, and the occasionally seen night -time glow of the Aurora Australis (Southern Lights).
Stewart Island is named after William Stewart, who began charting the southern coast of the island in the early 1800 while on board the sealing vessel Pegasus.

According to the book, seriously you didn't think I would remember how to spell all of that did you lol
