Tongan DNA
Genetic origins and closest populations · Tonga · Oceania
Tonga holds the oldest Lapita settlement found so far in Polynesia, at Nukuleka on Tongatapu, dated to about 2,800 years ago. It is also the only Pacific island kingdom that was never formally colonised. In our model, the Tongan average is 75.5% Southern Chinese Neolithic farmer and 24.5% Papuan and Near Oceanian, a larger Papuan-related share than in the Samoan (18.0%) or Tahitian (19.7%) averages. The neighbours are unexpected: the closest modern average is Micronesian (0.019), then the Anakalangu and Kambera of Sumba in eastern Indonesia, with Tahitians at 0.0395 and Samoans only at 0.049. The ancient results point the same way, with the Saudeleur period of Nan Madol on Pohnpei in Micronesia (0.0144) and Early Bronze Age people from Morotai in the northern Moluccas (0.018) as the closest groups. Distances like these depend on the sample sets available, but they show how closely the island peoples of Micronesia, eastern Indonesia and Tonga are related.

This page sums up what the DNA of the Tongan sample tells us about deep origins. It is built from the averaged Global25 (G25) coordinates of individuals sampled in Tonga, and it is one of 335 populations in our atlas. An average describes the group as a whole, not any single person in it.
Ancient make-up of the Tongan average
In a model built from deep ancestral reference populations, the largest share of the Tongan average, 75.5%, goes to Southern Chinese Neolithic farmers, ahead of Papuan and Near Oceanian (24.5%). The Southern Chinese Neolithic farmers component reflects the Neolithic rice and millet farmers of southern China, whose descendants spread into Southeast Asia. The Papuan and Near Oceanian share (24.5%) reflects the ancestry of the first peoples of New Guinea and Australia. With well over half of the total, this single source dominates the profile.
The fit is loose (fit distance 0.043), which usually means that none of the available reference populations is a close stand-in for part of this ancestry, so read the percentages as rough. This population was modelled with a global set of reference populations (ancient genomes, plus modern stand-ins where no suitable ancient genome exists), because West Eurasian sources alone cannot describe it.

Closest modern populations to Tongan
Ranking every modern population by genetic distance puts Micronesian first for Tongan, at 0.019, then Anakalangu and Kambera (Wunga). By the tenth closest (Bajo) the distance grows to 0.063, a common pattern for a population that shares ancestry with its neighbours while keeping a profile of its own.
| # | Population | Distance | Closeness |
|---|---|---|---|
| 1 | Micronesian | 0.0190 | Very close |
| 2 | Anakalangu | 0.0367 | Close |
| 3 | Kambera (Wunga) | 0.0381 | Close |
| 4 | Tahitian | 0.0395 | Close |
| 5 | Kambera (Rindi) | 0.0428 | Close |
| 6 | Samoan | 0.0490 | Close |
| 7 | Manggarai (Rampasasa) | 0.0593 | Moderate |
| 8 | Manggarai (Bere) | 0.0593 | Moderate |
| 9 | Manggarai (Cibal) | 0.0610 | Moderate |
| 10 | Bajo | 0.0629 | Moderate |
Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.
Closest ancient populations to Tongan
If we search ancient DNA for the best match to Tongan, Federated States of Micronesia Pohnpei Nan Madol Saudeleur Period (Saudeleur period, c. 1100-1630 AD) comes first, at 0.014, with Federated States of Micronesia Pohnpei Na Island Early Modern next. That is a very close match, which suggests strong genetic continuity between those ancient people (or close relatives of theirs) and the modern population. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from Tonga
Our ancient DNA database holds 4 individuals excavated in present-day Tonga, dated from about 705 BC to 1106 AD. The most frequent Y-DNA haplogroups among them are O1a (1), and the most frequent mtDNA haplogroups are B4 (3). These are people who lived on the same land in the past, not necessarily ancestors of today's Tongan population.

About these numbers
Keep in mind that a population average is a statistical summary of a limited number of sampled individuals. Real people inside any group vary, some carry more of one ancestry and some less, and no genetic profile decides who is or is not Tongan. Use these numbers as a map of deep ancestry, not as a label.
Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.

The closest ancient matches are Federated States of Micronesia Pohnpei Nan Madol Saudeleur Period, Federated States of Micronesia Pohnpei Na Island Early Modern and Indonesia Morotai EBA Aru Manara.
Can a DNA test tell me if I am Tongan?
No DNA test can confirm an ethnicity or a nationality. What DNA can show is how similar your genome is to the sampled Tongan average and to its neighbours. If you have G25 coordinates, paste them in the comparison box on this page to check that for free.
Which ExploreYourDNA report suits Tongan ancestry?
Lapita – Austronesian & Pacific Report is our regional report for this part of the world. On the Tongan average its fit test reads partial, so check your own DNA first: the free Report Finder runs that test on your file.
Where does the data on this page come from?
From the averaged Global25 (G25) coordinates of the sampled individuals: genetic distances to other modern and ancient population averages, and a non-negative least-squares model against deep ancestral reference populations.
