According to tribal narratives, Kupe was the first Polynesian to discover the islands of New Zealand. His journey there was triggered by difficulties with fishing in Hawaiki, his homeland. Apparently the problem was a great octopus belonging to Kupe’s competitor, Muturangi.
Kupe set out in his canoe to kill the octopus, and such was the length of the pursuit that it brought him to New Zealand. With a companion known as Ngake (or Ngahue) in another canoe called Tāwhirirangi, he pursued the creature all the way to Cook Strait (known as Raukawakawa), where it was finally destroyed. It is said that his wife, Kuramārōtini, devised the name of Ao-tea-roa (‘long white cloud’) on seeing the North Island for the first time.
