Humans first arrived in New Zealand in the mid to late 1200s AD, making it the last major landmass on Earth to be settled. Polynesian voyagers reached the North Island between 1250 and 1275 AD, with the South Island following about a decade later, between 1280 and 1295 AD. These settlers, the ancestors of the Māori people, sailed from East Polynesia in double-hulled canoes across roughly 3,000 kilometers of open ocean.
How Scientists Pinned Down the Date
For decades, estimates for the initial settlement ranged broadly from the 12th to the 14th century AD. A 2022 study published in the Proceedings of the National Academy of Sciences narrowed that window considerably by modeling a large dataset of radiocarbon dates from both terrestrial and marine samples. The result was unambiguous: settlement began in the mid to late 13th century, with the North Island settled first and the South Island reached within a decade or two.
One of the most useful tools for dating early human presence in New Zealand is a volcanic eruption. The Kaharoa eruption from Mt Tarawera, dated to 1314 AD, deposited a distinctive layer of volcanic ash across much of the eastern and northern North Island. At 19 natural sites where this ash layer is preserved, the sustained decline of tall trees and the rise of bracken fern spores (a signature of human-set fires) essentially coincides with or comes just after that 1314 date. This gives researchers a precise geological marker: deforestation by fire began right around that time.
Charcoal preserved in soil and lake sediments tells a similar story. Across most of the country, major forest disturbance and clearance began between 1200 and 1400 AD. Some coastal regions weren’t significantly burned until centuries later, but the overall pattern consistently points to the 13th century as the starting point of human impact on the landscape.
The Pacific Rat as a Proxy for People
The Pacific rat, known as kiore, traveled with Polynesian voyagers throughout the Pacific. It couldn’t have reached New Zealand on its own, so dating its arrival effectively dates human contact with the islands. For a time, radiocarbon dates on Pacific rat bones suggested rats might have arrived as early as 50 to 150 AD, which would have implied human contact more than a thousand years before any archaeological evidence of settlement. That claim was controversial because it would also predate the settlement of tropical eastern Polynesia, the homeland the voyagers came from.
Researchers tested this by dating a different kind of evidence: seed cases preserved in wetland sediments that show distinctive gnaw marks from rats. The oldest rat-gnawed seeds from widely separated sites across New Zealand are consistent with rats arriving alongside the initial human settlement in the 13th century, not before. This independent line of evidence effectively ruled out the earlier dates on rat bones, which were likely skewed by contamination or other measurement issues.
Where the Voyagers Came From
The settlers who reached New Zealand came from East Polynesia, specifically the Society Islands (which include Tahiti), the southern Cook Islands, and the Austral Islands in French Polynesia. These island groups, sometimes referred to collectively as “Hawaiki” in Māori oral tradition, served as the staging ground for some of the most ambitious ocean voyages in human history.
Sailing simulations using reconstructions of ancient Polynesian canoe designs estimate the passage from East Polynesia to New Zealand took roughly 10 to 11 days under sail. These weren’t accidental driftings. The double-hulled canoes were purpose-built ocean vessels, and the voyagers navigated using stars, ocean swells, wind patterns, and the behavior of seabirds.
More Than a Single Canoe
Genetic research has shed light on the scale of the founding settlement. By comparing mitochondrial DNA diversity in modern Māori populations with that of eastern Polynesian populations, researchers estimated the founding population included approximately 50 to 100 women. The most likely number was around 70 female founders, with a 95% confidence interval of 50 or more.
This finding is significant because it rules out colonization by a single canoe or even a handful of small boats. A population of that size points to a deliberate, organized migration, likely involving multiple voyaging canoes arriving over a relatively short period. It aligns with Māori oral traditions describing a fleet of named canoes that made the journey to Aotearoa.
No Evidence of Earlier Settlement
New Zealand has no credible evidence of human habitation before the Polynesian arrival in the 13th century. There were no earlier waves of migration, no pre-Māori inhabitants. The Moriori people, sometimes incorrectly described as a pre-Māori population, were actually a Māori group who migrated from mainland New Zealand to the Chatham Islands, likely in the 15th or 16th century.
Every line of evidence converges on the same conclusion. Radiocarbon dating of archaeological sites, volcanic ash stratigraphy, pollen records showing deforestation, charcoal deposits from landscape burning, rat-gnawed seeds, and genetic analysis all point to the same narrow window. New Zealand was uninhabited until Polynesian voyagers arrived around 1250 to 1300 AD, roughly 750 years ago. It remains the most recent major human colonization event in world history.
