Checklist of Endemic Animal and Plant Families
This list of animal and plant families found exclusively in New Zealand is based on the taxonomy used in the Mammal Diversity Database (2020) for mammals, del Hoyo & Collar (2014 & 2016) for birds, the Reptile Database (2018) for reptiles, AmphibiaWeb (2018) for amphibians, Eschmeyer's Catalog of Fishes (2023) for fishes, and Mabberley (2017) for vascular plants. Invertebrates are based on Zhang (2013), Zhang (2011), and Roskov et al. (2014) depending on the group. Families described after these sources are indicated by the year of description. For further details on the sources and possible inaccuracies in the list see Sources & Caveats.
