The islands of New Zealand are believed to be fragments from the Gondwanaland supercontinent that are now over 2 000 km from either Australia or Antarctica. Despite this, the marine fish parasitic copepod fauna is neither isolated nor distinctive, but reflects the southward extension of the tropical Indo-Pacific fauna and also the circumpolar element. Only one of the 49 known genera, representing 18 families, is endemic and speciation within all the families is low. Although the origin of the marine fish parasitic copepod fauna can be explained in terms of host dispersal patterns, the derivation of the euryhahne endemic Abergasilus and the freshwater Paeonodes and Thersitina is still an enigma. The copepod associates of the invertebrates are still virtually unknown and no conclusions can be drawn.
