The monophyly of the endemic New Zealand wattlebirds (Callaeatidae) was examined through the sequencing of nuclear RAG-1 and c-mos genes and comparison to other passerine sequences. The New Zealand wattlebirds were strongly supported to be monophyletic and were nested within Corvida. An estimate for the time of divergence of the New Zealand wattlebirds indicated that the ancestors of this family arrived via transoceanic dispersal after the separation of New Zealand from Gondwana. Long branches separated the three New Zealand wattlebird genera from one another and relationships among them were unresolved, even in analyses ...

Long branches separated the three New Zealand wattlebird genera from one another and relationships among them were unresolved, even in analyses including a further 1.5 kb of mitochondrial DNA sequences. However, most of the analyses supported either a basally diverging huia or kokako.
