Polynesian people touched down on Aotearoa 1000 years ago. Individual people came by canoe, which Maori people used well sailing on the verge of death. Some of the boats had single hulls, without riggers or double hulls. There was plunks slashed together, which were 15 to 25 meters long.
Trained navigators steered under a direct trail of stars by night and sea swells by day. Not many of them managed to cross the dangerous seas of Aotearoa.
