The frequency of artefacts found at each archaeological site.
Fig 2.
A bipartite network of obsidian sources and archaeological sites, with links (edges) indicating the frequency of artefacts associated with each source-site pair.
Fig 3.
Archaeological site communities with similar proportions of obsidian from specific sources.
The relative thickness of the links indicates the strength of similarity. Site Community A coloured light green; Site Community B coloured light blue; Site Community C coloured pink.

Fig 5.
Archaeological site communities taking into account the revealed comparative abundance (RCA) of obsidian for each site-source pair.
The relative thickness of the links and the spatial relationship of the nodes reflects similarity. Site Community A coloured light green; Site Community B coloured light blue; Site Community C coloured pink.

The relative thickness of the links and the spatial relationship of the nodes reflects similarity. Source Community 1 coloured dark green; Source Community 2 coloured dark blue.

A bipartite network of obsidian source communities and archaeological site communities, with links indicating the frequency of artefacts associated with each source-site pair.
Fig 9.
The spatial distribution of obsidian source communities and archaeological site communities.
The links between sites and sources are colour coded according to the sites. The weighting of the links reflects the frequency of artefacts found at that site made out of the source material. Contains data sourced from the LINZ Data Service licensed for reuse under CC BY 4.0.

Examples of some contemporary iwi boundaries (http://www.tkm.govt.nz/) and the spatial distribution of obsidian source communities and archaeological site communities.
Many other iwi have manawhenua authority in the region and have rohe territorial boundaries that overlap with those shown. The rohe territories shown were chosen to display the overlap in rohe and the coincidence between the boundaries and the source and archaeological site communities.
