ABSTRACT The Tiwai Point site in Bluff Harbour, Murihiku (Southland) was occupied early in the first century of New Zealand settlement (∼1300 AD). The site was the largest production center of Bluff argillite adzes that supplied settlements up to 500 km distant. This tough recrystalized mudstone was obtained from sources throughout Bluff Harbour and it presented new opportunities and challenges to pioneering Polynesian adze makers. Although suitable for producing Polynesian adze forms, it is tougher than tropical Polynesian basalts and required the development of novel manufacturing techniques. To understand these technological innovations, we produced 155 3D models of Bluff argillite adzes, preforms and blanks from the 1968 Tiwai Point excavation to model adze manufacture using various forms of the raw material. We found a heavy reliance on hammer-dressing as a practical means of working an unusually tough material with variable grain-size anda high potential risk of breakage.

在新西兰Murihiku的Tiwai Point，将波利尼西亚的Adze技术应用于新原料

摘要位于穆里希库（南国）布拉夫港的提威角遗址在新西兰定居点的第一世纪初期（约1300年）被占领。该场址是布拉夫（Bluff）闪锌矿ad石的最大生产中心，可提供远至500公里的定居点。这种坚硬的重结晶泥岩是从布拉夫港（Bluff Harbor）的资源中获得的，它为波利尼西亚的先河制冰者提供了新的机遇和挑战。尽管它适合于生产波利尼西亚的ze石形式，但它比热带的波利尼西亚玄武岩坚硬，因此需要开发新的制造技术。为了了解这些技术创新，我们从1968年的Tiwai Point开挖中制作了155个3D的布拉夫（Bluff）凹凸棒状坯料，预成型坯和毛坯3D模型，以使用各种形式的原材料来制造模型。
