Radiocarbon dating of Pacific rat (kiore) evidence (including rat-gnawed seeds and rat bones) has been used as a proxy for initial human presence, since kiore could only have reached Aotearoa with people. A widely cited analysis places the rat’s introduction to both main islands at about 1280 CE, supporting a late and relatively rapid colonization model.
At Wairau Bar (Marlborough), high-precision dating programs using materials such as moa eggshell have placed key occupation phases in the late 1200s to early 1300s CE. The site is significant for understanding early settlement lifeways, long-distance connections, and rapid establishment of communities soon after arrival.
Pollen and charcoal records show that by around 1300 CE there was widespread conversion from forest to bracken fern and scrub, indicating extensive burning associated with early settlement and land-use (including creating space and facilitating cultivation and food gathering). This strengthens the case for swift ecological impacts following colonization.
The Kaharoa eruption of the Mount Tarawera volcanic complex spread a distinctive tephra layer across parts of the North Island. This ash horizon (often dated to 1314 ± 12 CE) became a crucial reference point for testing whether archaeological evidence of people occurs above (later than) or below (earlier than) the tephra in sediment sequences.
Stratigraphic studies emphasize that direct archaeological evidence of human settlement has not been confidently identified beneath major tephra markers such as the Kaharoa ash layer, reinforcing the mainstream view that substantial settlement post-dated the early 14th century marker (even if limited earlier presence is debated).
Syntheses of archaeological and paleoenvironmental evidence commonly describe broader and more widespread settlement developing in the early-to-mid 1300s CE, following initial landfalls and reconnaissance. This pattern aligns with the rapid appearance of impacts in ecological records and the clustering of early site dates.
Archaeological work on Enderby Island (Auckland Islands) identified evidence that a Polynesian group and their dogs camped there for at least one summer during the 13th or 14th century, representing the southernmost confirmed extent of Polynesian settlement/voyaging discovered to date in that region.
Early archaeological deposits and modeled exploitation histories indicate intensive hunting of moa soon after colonization, consistent with rapid human expansion and high reliance on large, naive avifauna in some regions during the initial centuries of settlement.
High-precision radiocarbon chronologies indicate moa extinction was rapid, occurring in little more than ~200 years after initial human settlement, with broadly contemporaneous losses across distant regions—an important benchmark for understanding the ecological consequences of first colonization in Aotearoa.
By the 2000s, multi-proxy approaches—combining archaeological site dates, tephrochronology, and commensal species evidence (kiore)—helped consolidate a mainstream model of colonization clustered in the late 1200s to early 1300s CE, reducing support for much earlier settlement claims.
Late 2000s–early 2010s re-dating efforts at Wairau Bar using improved radiocarbon methods helped refine the site’s placement near the beginning of the settlement era, shaping interpretations of early community duration, mobility, and regional development during the colonization phase.
A major high-precision synthesis of moa extinction timing (using extensive radiocarbon datasets) reinforced the view of rapid, post-settlement megafaunal collapse, providing one of the best-resolved global case studies for human-driven extinction following island colonization.
