Only Polynesians as they are genetically mostly SE Asian-related (Taiwan Aborigine) with significant Oceanian/Papuan admixture.
The Indigenous peoples of South America aren't a part of the Indo-Pacific family though . Natives in general are genetically very different from people in the Indo Pacific region. They have been diverged from people in Asia for at least 15000 years. Also they are mostly a mix of Siberians with very significant ANE ancestry (at around 30-40% or more) which is very different from Indo-Pacific peoples. This include the Amazonians who can look more pseudo SE Asian, they are genetically very different despite some superficial facial similarities.
ANE is an ancient West Eurasian population mostly Sungir/Kostenki-related with around 1/4 East Eurasian (Tianyuan-related rather than Onge).
Indo-Pacific peoples in general have 0% ANE while Indigenous in South America are around 30-40% ANE at least.
