Rich pickings: An analysis of opportunistic behaviour at Rangitoto Island, Aotearoa/New Zealand

Rangitoto Island, Aotearoa/New Zealand, is the location of a graveyard of abandoned vessels and three communities of baches (circa 1910s–1930s)—small and modest holiday homes. In 2014, an archival and archaeological investigation of 11 discarded watercraft located at Boulder Bay and the bach communities of Beacon End, Rangitoto Wharf and Islington Bay revealed evidence of salvage and reuse of abandoned vessel materials in the construction, modification and use of the island’s baches. This evidence in turn provides insight into opportunistic behaviours of communities unassociated with the maritime industries that created ships’ graveyards, and consequently affords a more well-rounded understanding of post-depositional site formation processes. Influenced by social and economic impacts, the Rangitoto Island bach communities’ resourcefulness enhances our knowledge of behaviours towards ships as sources of material.
