I’ve been playing around a bit with Poi’s Runner and modelling various Southeast Asian and Oceania populations to see if I can create a migration map of sorts, tracing my minor Polynesian through Southeast Asia to New Zealand. I must admit my understanding of the statistics and analysis associated with G25 coordinates and the interpretation is not as good as many of you here, so please correct me if I’m wrong on anything.
To begin with on paper my Māori ancestry is very minor (around 1%), however I want to see if it’s possible to model components of Polynesian DNA to see if I have trace amounts within that of the areas Polynesian’s migrated through over several thousands of years. For those of you not overly familiar with Polynesian and Māori migration, here is a quote from this article (https://www.culturalsurvival.org/news/genetic-link-brings-indigenous-taiwanese-and-maori-together) which sums it up well:
Thousands of years later (8,000 to 10,000 years ago) members of the Austronesian language group traveled south from Taiwan and passed through the Philippines and Indonesia. Along the way the Papuans and Austronesians intermarried, giving birth to contemporary Polynesians and ultimately settling in what is now New Zealand. "The Maori are the ultimate end product of these voyage and colonization processes," said Chambers, adding that "a ‘genetic trail’ links New Zealand Maori back all the way to the indigenous people of Taiwan, as do Austronesian languages.
Here is a map using data from this article (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4143916/) that show’s the migration path’s in Asia and Oceania, and the ancestral components of each population. Polynesian’s are mostly Austronesian and Papuan.

Besides Māori, I went and swapped it out for every Austronesian and Melanesian population in the G25 calculator to see how interchangeable Māori is. I don’t match every population, but I match a few from Philippines, Indonesia and Papua New Guinea. My highest percentage is Nasoi (1.67%) from Bougainville Island, one of the islands of Papua New Guinea. I get this using a different model which I haven't listed here, as its fit is slightly higher (1.1635). This is shown in the map from ph2ter.

Below I’ve listed each population I match, with the closet fit from top to bottom, and the distance to each sample in that population. Interestingly (but maybe not surprising), the 0.83% I get for Māori is the same for every Austronesian and Papuan population I match (besides Nasoi).

I’ve done a quick diagram to map out the migration path using these results.

Its interesting to see that G25 coordinates can be useful in this way, even for very minor components. It would be great to see what this would look like for someone with more substantial Polynesian DNA. I can only surmise that the 0.83% is the same for all of them because they are interchangeable in a sense. You can’t have Polynesian without Papuan, Indonesian or indigenous Filipino. I’m not sure why I’m closer to Papuan populations. I assume I inherited more of this component. I hope whoever reads this finds it interesting. If you have any comments or if I've have made errors, please correct me.
