This paper describes attempts to develop tree-ring chronologies from New Zealand matai (Prumnopitys taxifolia) and miro (Prumnopitys ferruginea). These tree species have been recovered from Māori archaeological contexts, including as objects such as canoes and palisade posts. Dendrochronology offers the potential to establish accurate and precise calendar dates for wooden objects but relies on cultural use of species that are also suitable for tree-ring analysis, and the availability of calendar-dated reference chronologies for crossdating wood of unknown age. We used archived cross-section and core samples from seven sites in central North Island, and nineteen core samples collected in 2019 from matai and miro trees at Pureora Forest Park for our analysis. Some of these samples came from long lived trees, with ring counts indicating ages up to 800 years old. We found that both matai and miro exhibit considerable variability in ring clarity and ring width. They also have ring anomalies affecting the reliability of ring-width series. Miro was very challenging, and no tree sequences were built for this species. Tree-ring sequences were built for several matai samples but no secure inter-tree matches were identified. Further analysis of matai samples is required to establish reliable tree ring patterns for inter-tree and inter-site crossmatching.

本文描述了从新西兰 matai ( Prumnopitys taxfolia ) 和 miro ( Prumnopitys ferruginea )开发树轮年表的尝试。）。这些树种是从毛利考古环境中恢复的，包括独木舟和栅栏柱等物品。树木年代学提供了为木制物体建立准确和精确的日历日期的潜力，但依赖于也适合树轮分析的物种的文化使用，以及用于对未知年龄的木材进行交叉测年的日历日期参考年表的可用性。我们使用了来自北岛中部七个地点的存档横截面和核心样本，以及 2019 年从 Pureora 森林公园的马泰树和米罗树收集的 19 个核心样本进行分析。其中一些样本来自长寿树，年轮计数表明年龄高达 800 岁。我们发现 matai 和 miro 在戒指清晰度和戒指宽度方面表现出相当大的变化。它们也有影响环宽系列可靠性的环异常。Miro 非常具有挑战性，没有为这个物种建立树序列。为几个 matai 样本构建了树轮序列，但没有确定安全的树间匹配。需要对马泰样本进行进一步分析，以建立可靠的树木年轮模式以进行树间和站点间交叉匹配。
