Native Americans and Polynesians Met Around 1200 A.D.
Genetic analysis of their modern descendants shows that people from the Pacific Islands and South America interacted long before Europeans arrived

I read this article, and it goes into significant genetic markers of Native Americans dating to the 1200s in the Marquesas islands in Polynesia, among other indicators of sustained contact between Pacific coastal South America and Polynesia.
The Maori settled NZ from Eastern Polynesia during the 1300s. Some of the settlement wave at least came from atolls and archipelagoes near the Marquesas like Cook island and Society Island.
So WI the original Maori population group of Polynesians hear of South America and try their warrior culture out there?
I see a few potential outcomes.
The 1300s are the early Inca Empire, with Cusco founded in the late 1200s.
So, the Maori could conquer and usurp the Inca early on.
Or they could become a mercenary or powerful vassal that eventually challenges the Inca.
Or they could settle away from the main center of power and become enemies/rivals of the Inca or get in fights with other groups on the Colombian coast, where the genetics indicate many of the mixture of Native American and Polynesian DNA originates, making it a likely destination if known.
There would be considerable cultural and technological changes from this.
