description: The rich bryozoan fauna living in the sea around New Zealand at the present day is among the best known globally. However, despite the abundance of bryozoans in Cenozoic deposits onshore, little is known about these faunas and therefore the origin of the modern fauna. Here we describe a previously unstudied bryozoan fauna from the Tumaio Limestone of Early Eocene age on Chatham Island, totalling 77 species (22 Cyclostomata, two Ctenostomata and 53 Cheilostomata). The following new taxa are introduced: <i>Plagioecia zatoni</i> sp. nov., <i>Mesenteripora jamesi</i> sp. nov., <i>Platonea dilatata</i> sp. nov., <i>Zagorsekia</i> gen. nov., <i>Heteropora scholzi</i> sp. nov., <i>Conopeum stamenocelloides</i> sp. nov., <i>Tumaiella dieffenbachi</i> gen. et sp. nov., <i>Marssonopora connexa</i> sp. nov., <i>Amphiblestrum paleogenicum</i> sp. nov., <i>Dactylostega spiralis</i> sp. nov., <i>Pyrisinella primazelandiae</i> sp. nov., <i>Chaperiopsis cookae</i> sp. nov., <i>Pseudothyracella campbelli</i> sp. nov., <i>Cladobryopastor philipi</i> gen. et sp. nov., <i>Floridina elegans</i> sp. nov., <i>Onychocella subtriangulata</i> sp. nov., <i>Melychocella bilamellata</i> sp. nov., <i>Melychocella obliqua</i> sp. nov., <i>Aspidostoma clava</i> sp. nov., <i>A. gelasinus</i> sp. nov., <i>A. twinn</i> sp. nov., <i>A. lamellatum</i> nom. nov., <i>Micropora chathamica</i> sp. nov., <i>Andreella dubia</i> sp. nov., <i>Cellaria bicuspidata</i> sp. nov., <i>C. gigas</i> sp. nov., <i>C. inarticulata</i> sp. nov., <i>C. palatum</i> sp. nov., <i>Quasitrilaminopora curiosa</i> gen. et sp. nov., <i>Moyanopora hugoi</i> gen. et sp. nov., <i>Arachnopusia dimorpha</i> sp. nov., <i>Exechonella chathamensis</i> sp. nov., Diedroporidae fam. nov., <i>Diedropora gravabilis</i> gen. et sp. nov., <i>Adeonellopsis incompta</i> sp. nov., <i>Multescharellina pisiformis</i> sp. nov., <i>Chataimulosia revelator</i> sp. nov., <i>Porella tiorioriensis</i> sp. nov., <i>Hemicyclopora dissidens</i> sp. nov., <i>Hemicyclopora ventricosa</i> sp. nov., <i>Exochella abigailae</i> sp. nov., <i>E. reidae</i> sp. nov., <i>E. woodae</i> sp. nov., <i>E. linearis</i> sp. nov., <i>Illusiopora bifax</i> gen. et sp. nov., <i>I. recta</i> gen. et sp. nov., <i>Gigantopora modesta</i> sp. nov., <i>G. grandis</i> sp. nov., <i>Porina turrita</i> sp. nov., <i>Lacerna ordinaria</i> sp. nov., <i>Phonicosia sinuosa</i> sp. nov., <i>Macrocamera obesa</i> sp. nov., <i>Siphonicytara primitiva</i> sp. nov., <i>S. litotes</i> sp. nov., <i>Osthimosia aurora</i> sp. nov., <i>O. curiosa</i> sp. nov. and <i>Reteporella mediocris</i> sp. nov. Keys are given for New Zealand Cenozoic species of <i>Aspidostoma</i> and <i>Cellaria</i>. The Tumaio bryozoan fauna shows a high degree of endemicity, contains the earliest known records of several cheilostome families, and small colonies of encrusting species that may represent the oldest example of an ‘interstitial’ bryozoan fauna.http://zoobank.org/urn:lsid:zoobank.org:pub:2865FDB5-D812-4102-B5E2638549D16C95
