The 79 species of athecate hydroids and Anthomedusae known from New Zealand are surveyed. Their systematic revision is based on preserved museum material, newly collected living material, and life cycle observations. Sixteen new species, including three new genera and fourteen new records are described. Full definitions for all taxa are given and almost all species are depicted. One new family Eucodoniidae is defined and incorporated into the order Filifera. The new family includes only the species Eucodonium brownei Hartlaub, 1907. The three new genera are Fiordlandia (family Hydractiniidae), Barnettia (family Pandeidae), and Fabienna (family Proboscidactylidae). The genus definition of Zanclea is widened to include also the genera Zanclella and Halocoryne. The new species are: Barnettia caprai, Bougainvillia dimorpha, Corymorpha intermedia, Coryne tricycla, Ectopleura multicirrata, Eudendrium maorianus, Euphysa problematica, Fabienna sphaerica, Fiordlandia protecta, Hydractinia novaezelandiae, Hydractinia rubricata, Merga treubeli, Podocoryna australis, Rhizogeton conicum, Staurocladia wellingtoni, Stylactaria otagoensis, Zanclea polymorpha. Two possible new species of the family Corynidae are not named specifically due to insufficient life cycle information. The life cycles of Bougainvilla vervoorti Bouillon, 1995, Bougainvillia dimorpha new spec., Podocoryna australis new spec. and Zanclea polymorpha new spec. are described. Ascidioclava parasitica Kirk, 1915 is referred to Bythotiara parasitica new comb. and its life cycle partially revealed. Cladonema novae-zelandiae Ralph, 1953 is referred to Cladonema radiatum Dujardin, 1843. Tubiclava rubra Farquhar, 1895, Corydendrium rubra Stechow, 1924, and Corydendrium zelandicum Stechow, 1924 are recognised as new synonyms of Turritopsis nutricula McCrady, 1859. Coryne tenella Farquhar, 1895 is redescribed from its type locality and synonymised with Sarsia eximia. Based on the examination of new living material of Solanderia ericopsis (Carter, 1873), the genus Chitina Carter, 1873 is again sunk into synonymy with Solanderia Duchassaing & Michelin, 1846. Pochella oligonema Kramp, 1955 is referred to Fabienna oligonema new combination. Life cycle observations for other species were made to confirm their identity. New records are: Calycopsis bigelowi Vanhoeffen, 1911, Dicoryne conybearei (Allman, 1864), Amphinema dinema (Péron & Lesueur, 1809), Halitholus pauper Hartlaub, 1914, Cladocoryne floccosa Rotch, 1871, Ectopleura crocea (L. Agassiz, 1862), Coryne pusilla Gaertner, 1774, Sarsia japonica (Nagao, 1962). Several other possible new records were not assigned to a species due to insufficient life cycle information.
