  Abstract = {Tāmure (Australasian snapper, Chrysophrys auratus) is the most commonly identifed fsh in pre-European Māori middens 
in northern New Zealand. Tāmure reproduce in open water, after which their larvae migrate to nurseries in sheltered inshore 
environments. The range of suitable nursery habitats in the Hauraki Gulf has declined over the last century as agriculture and 
industry have had an impact on the quality of inshore waters. In this study, we address the question of whether pre-European 
Māori activities in the coastal zone also caused a decline in the range of nursery habitats available to tāmure populations. 
We compare the trace element chemistry of tāmure otoliths from four Hauraki Gulf assemblages using LA-ICP-MS. The frst 
assemblage is from an archaeological site dating to the mid-ffteenth century AD; the second is from a sixteenth–seventeenth 
century AD site, while the other two are from modern fsh catches close to archaeological sites. We examine the portion 
of the otolith relating to the larval and post-larval phases. Our results demonstrate both temporal and spatial variation in 
otolith chemistry concentrations in the immediate post-larval phases of otolith growth. This in turn suggests changes in the 
geochemistry of nursery zones through time and space. This provides a potential tool for evaluating indigenous efects on 
inshore fsheries from midden data. It also demonstrates the value of establishing pre-industrial baseline information from 
the archaeological record for coastal ecology studies.},
