The history of the Māori people was only recorded orally for many generations until Europeans came to New Zealand and began writing down everything they learned. The first encounter by Europeans with the Māori was not pleasant and friendly. More than likely it was a misunderstanding of the Pōwhiri.
The Pōwhiri is a welcoming ritual and part of it involves three warriors advancing and showing off their skills before making an offering to the newcomers. If the offering is picked up, then the strangers are considered peaceful. If it is not, then the strangers become hostile or untrustworthy to the Māori. Four sailors and only one Māori were killed in that encounter. Apparently the story that was told to the rest of the world was frightening enough that no explorers returned for decades.
