The genus Nelepsittacus consists of four extinct parrot species and is closely related to the genus Nestor. All recovered from early Miocene Saint Bathans Fauna from the Lower Bannockburn Formation in Otago in New Zealand, three of the four species have been named. Features in their skeletons, namely the coracoid, humerus, tibiotarsus, and tarsometatarsus, that they share only with the Nestor parrots link them to that genus.
