新西兰考古研究通过高精度放射性碳定年和统计模型，为早期毛利人社会的演变勾勒出更精确的时间轴。1研究人员分析了Waihemo和Kokohuia两处遗址的考古证据，将事件的时间范围精确到20至30年左右，相当于一代人的时间跨度。1
早期波利尼西亚定居者约750年前抵达新西兰。1Waihemo遗址在1320至1440年间被反复使用，而非此前认为的仅20至50年。1约在1410年左右，该遗址的居民食物来源发生明显转变，从狩猎大鸟和海豹逐步转向贝类、鱼类、狗和野生鸟类。1同样位于研究范围内的Kokohuia遗址的烤炉年代约为1440年。1
此项研究采用了"摇摆匹配"等放射性碳测年技术，使考古证据与毛利人口头传统之间的联系更加清晰。1
Archaeological research in New Zealand has refined the chronology of early Māori society development through advanced radiocarbon dating and statistical modeling techniques.1 By analyzing evidence from the Waihemo and Kokohuia sites, scientists have clarified when key economic transitions occurred and connected archaeological findings more directly to Māori oral traditions.1
Early Polynesian settlers arrived in New Zealand approximately 750 years ago.1 The Waihemo site shows evidence of repeated occupation between 1320 and 1440, a substantially longer period than the 20 to 50 years previously estimated.1 Around 1410, residents of Waihemo shifted their primary food sources from hunting large birds and seals to collecting shellfish, fish, dogs, and wild birds.1 At the Kokohuia site, ovens date to approximately 1440, with food remains accumulated over about 1600 years.1
The research employed specialized techniques including "wiggle-matching" to narrow the margin of error in radiocarbon measurements, allowing researchers to pinpoint the timing of events to within 20 to 30 years—roughly a single generation.1
