It is a compilation of a number of independent projects conducted in the laboratories of the University of Auckland and University of Otago from 2011 to 2018 [1–13]. It combines previously published studies [3, 5–13], an MA thesis [1], a BA(Hons) dissertation [2], a site report [4], and other previously unpublished primary data. The dataset has high reuse potential for future non-destructive studies of artefacts and social network analyses.

It also discusses the heritage legislative regime under which the remains are protected, the vessel's history and archaeological significance and future research and public interpretation plans for the remains.

In select areas lacking sufficient rainfall for dryland production, irrigation from intermittent streams would have been a viable alternative. A number of intermittent irrigated agricultural systems have been recorded in leeward Hawaiian locations, with the ca. 33 km 2 Waimea Field System being the most extensive. We use computational fluid dynamics modelling within a digital elevation model based on high resolution terrestrial laser scanning data to investigate intermittent irrigation within a 2.4 ha study area of the Waimea Field System. The analysis documents variation within channels and terraces. Some channels are gradual downslope ditches with the potential to irrigate large areas via garden plot flow through. Feeding off of these ditches are channels running parallel to slope with constrained flows of higher velocity that fed lower terraces without depositing water on upper terraces. The system also included channels running along the front of terraces that redirected flows horizontally across slope by collecting excess water. Terraces varied in terms of the amount of water that they could receive. Many terraces received moderate volumes of water, whereas select terraces in the valley bottom received much higher volumes and were probably used to grow water demanding crops. Other terraces were not fed by channels and were probably used for rain-fed agriculture or residential purposes. Documenting variation within this small section of the Waimea field system provides an understanding of diverse agricultural practices and how these were used for subsistence and surplus production.

Our analysis of the surface archaeological remains on Ahuahu (Great Mercury Island, Coromandel) examines how communities practiced horticulture and interacted with their local ecological and social environments through mobility, storage and competition. Focusing on a 300 ha study area in the northern quarter of the island, we use a multi-scalar land-unit (LU) approach to categorize the landscape as a continuously varying phenomenon with multiple characteristics. Our results suggest that the largest concentrations of horticultural features were located in areas with high sunlight exposure (insolation), good soils, low slopes and stream access. This patterning indicates that specific areas were probably being targeted for horticultural production, although differential feature preservation and visibility must also be considered. The spatial organisation of storage pits, residential features and fortified locations suggests year-round occupation of the island, not just summer planting. The heterogeneous characteristics of the landscape influenced the settlement of three particular zones on the island. We suggest that the economic defensibility of these areas would have facilitated territoriality within a socio-historical context of population fluidity and mobility.

With the case study of Matakawau Paa (Tl0/169), Ahuahu (Stingray Point Paa, Great Mercury Island), New Zealand, I analyse a terrestrial laser scan point cloud to address how archaeological feature morphologies and spatial relationships reflect spatial logics of the last inhabitants of this Maaori headland paa (fortified or defended place). Feature shape and location in relation to other features, slope and aspect are considered, along with a least cost path analysis of likely routes of movement between features. Materialised ideologies relating to social hierarchy are argued to be apparent in the orientation and shape of the constructed features, a platform and adjacent terraces. Boundaries and pathways within the paa confined and redirected movement laterally to open communal areas.
