Twenty four species and two subspecies of bird lice are recorded from New Zealand for the first time. Also, 52 new host-louse associations are listed for louse species already recorded from New Zealand. The genera Cuculiphilus Uchida, 1926, Franciscoloa Conci, 1942, Penenirmus Clay & Meinertzhagen, 1938 and Psittoecus Conci, 1942 are recorded from New Zealand for the first time. Since the publication of the previous list of chewing lice from New Zealand birds, four further lice have been published as new species, and another identified and reported in the literature. One species has been synonymised and its name is deleted from the fauna. Considering the above additions, deletion and other amendments, the total number of species and subspecies of bird lice recorded from the New Zealand region and the Antarctic Ross Dependency is now 301. A further 105 records still remain at generic level only, but all these do not necessarily represent different taxa.
