Abstract
Scampi (Metanephrops challengeri Balss, 1914) support a significant fishery in New Zealand waters. Allozyme analysis of samples from four fishery areas found a low level of genetic variation but significant heterogeneity in allele frequencies. There were significant differences between samples from the Auckland Island Shelf and those from mainland New Zealand at three loci, but only one locus showed heterogeneity among mainland samples.
