Abstract

A Leslie matrix population model supported by carbon-14 dating of early occupation layers lacking moa remains suggests that human hunting and habitat destruction drove the 11 species of moa to extinction less than 100 years after Polynesian settlement of New Zealand. The rapid extinction contrasts with models that envisage several centuries of exploitation.

1. Climate was not a factor in the New Zealand Holocene extinctions. No New Zealand vertebrates are known to have gone extinct at the end of the Otiran Glacial and climatic fluctuations within the past 1000 years were minor in comparison to that event [R. N.
