Abstract The lithistid Demospongiae fauna of New Zealand is reviewed here following the extensive inventory, documentation and revision of the fauna over the period 1991 to 2006. Examination of almost 300 specimens led to the discovery of 29 species (13 of which were new to science) in 9 families. New species of the poorly known phymatellid genera Neoaulaxinia Pisera and Lévi, 2002 and Neosiphonia Sollas, 1888 were described, and a new corallistid genus, Awhiowhio Kelly, 2007, was recognised. All specimens were dredged from between 80 and 1700 m, but were most common between c.300-1100 m. With the exception of several specimens dredged from the Challenger Plateau to the west of New Zealand, the majority of specimens were found north of the Chatham Rise to the east, and in northern waters, contrasting markedly with what we know of the distribution of these sponges in the past. The availability of hard substrate, ocean circulation patterns, silica availability, and past and present water temperature, are key factors constraining the present day distribution of lithistid sponges in New Zealand.
