Raw Material Economisation in Aotearoa New Zealand: Evidence for Manufacture and Recycling of Adzes on Ahuahu Great Mercury Island

ABSTRACT Raw materials are used to characterise the early settlement of Aotearoa Te Wai Pounamu New Zealand by Māori. Current models suggest change in raw material use over time occurred in response to changing social organisation and reduced resource availability. However, few studies have examined spatial variation in raw material use. Here we examine four basalt artefact assemblages from Ahuahu Great Mercury Island to examine potential spatial variation and test the assumption of a lack of material economising in the earliest occupation. We explore this through the concept of adze recycling. Results suggest conservative use of basalt from the earliest occupation on Ahuahu through the recycling of adzes, with differences in resource use among adjacent locations. We suggest basalt use may have involved the bulk procurement of stone resources, provisioning of place and the recycling of material.
