Additional records are listed for Anseropoda aotearoa and Tremaster mirabilis novaecaledoniae. Clark Pseudarchaster jordani Fisher and small specimens of Ceramaster which may be two distinct species and a species of Marginaster, though these last three are not formally named. Also included are Mediaster australiensis H.L. They include the genera Patagiaster (Astropectinidae, Paxillosida), Astroceramus and Cladaster (Goniasteridae), two new genera in the families Goniasteridae and Odontasteridae, and new species in the genera Astroceramus, Cladaster, Ceramaster, Pillsburiaster (Goniasteridae), Marginaster (Poraniidae) and Podosphaeraster (Podosphaerasteridae) in the order Valvatida. An addendum includes species in the orders Paxillosida (1), and Valvatida (17) not previously recorded locally. At least 34 species are endemic, and only 8 are recorded from depths greater than 3000 m. The Spinulosida are decidedly shallower (0-1357 m), while the Brisingida (150-6160 m) are the only order not recorded from shallow water. The Velatida have the largest bathymetric range (0-6720 m), followed by the Forcipulatida (0-4405 m). The order Forcipulatida dominates the fauna in number of species and recorded occurrences, while the Spinulosida has least species and occurrences. Species not formally recognised are present in the Pterasteridae, Zoroasteridae, and Hymenodiscididae. New species are described in the families Pterasteridae and Myxasteridae (Velatida), and Pedicellasteridae, Zoroasteridae, and Asteriidae (Forcipulatida). One new genus is described in the family Asteriidae (Forcipulatida). Families new to the fauna are Myxasteridae (Velatida), Leilasteridae (Spinulosida), and Pedicellasteridae (Forcipulatida).
The order Velatida includes 5 families, 10 genera, and 23 species Spinulosida includes 2 families, 4 genera, and 14 species Forcipulatida 4 families, 17 genera, and 31 species and Brisingida 5 families, 8 genera and 15 species. In all, 16 families, 39 genera and 83 species are represented. The area includes the New Zealand Exclusive Economic Zone (EEZ), Lord Howe, Norfolk, and Macquarie Islands, the Kermadec Islands and associated ridges, and deeper basins and trenches. Sea-stars in the orders Velatida, Spinulosida, Forcipulatida and Brisingida are described for the New Zealand biogeographic region (latitudes 24° to 57° 30′ S, 157° E to 167° W).
