• Centroscymnus crepidater (Bocage & Capello, 1864).
• Scymnodon plunketi (Waite, 1910).
• Deania calcea (Lowe, 1839).

Family Dalatidae

• Dalatias licha (Bonnaterre, 1788).
• Scymnodalatias sherwoodi (Archey, 1921).

Family Echinorhinidae

• Echinorhinus brucus (Bonnaterre, 1788).
• Echinorhinus cookei Pietschmann, 1928

Compared with previous accounts of the New Zealand squaloids, of which the most recent (other than lists only) is by Phillipps (1946), five additional species are recognised. Phillipps lists ten squaloids, but one of these, Centrophorus waitei, is now known to be a juvenile of Scymnodon plunketi. Of the remaining nine of Phillipps' species, six have been found to be synonyms, and a seventh has been placed in another genus. Thus only Scymnodon plunketi and Oxynotus bruniensis remain without nomenclatural change. To facilitate comparison of Phillipps' list with the fauna as now known, the nomenclatural changes are shown below.

Additions to the fauna have been:

• Etmopterus baxteri
• E. lucifer
• Centroscymnus owstonii
• Centroscymnus crepidater
• Echinorhinus cookei

Two new species, Etmopterus baxteri and E. abernethyi, were recognised, but as more material became available E. abernethyi was found to be a growth stage of E. lucifer. A new genus, Scymnodalatias, was also recognised, but this is based on Scymnodon sherwoodi, a species previously known from New Zealand.
