Abstract
We report here the genetic diversity of killer whales around New Zealand and compare samples collected in this region (n = 11) with larger geographic databases of mtDNA control region sequences to investigate the relationship of the New Zealand killer whales with more distant populations/ecotypes. Eight variable sites defined four haplotypes, revealing a low mtDNA genetic diversity when compared with other cetacean species and to that observed worldwide for killer whales. The geographic distribution and segregation of haplotypes within New Zealand suggested that this population could be geographically structured. Only one of the New Zealand haplotypes matched with those from other distant regions (the Eastern North Atlantic and Western South Atlantic populations).
