The yellow-crowned parakeet (Cyanoramphus auriceps) is a species of parakeet endemic to the islands of New Zealand. The species is found across the main three islands of New Zealand, North Island, South Island and Stewart Island/Rakiura, as well as on the subantarctic Auckland Islands. Its Māori name is kākāriki.

The red-crowned parakeet or red-fronted parakeet (Cyanoramphus novaezelandiae), also widely known by its Māori name of kākāriki, is a small parrot from New Zealand. It is characterised by its bright green plumage and the red pattern on its head.

Malherbe's parakeet usually known as the orange-fronted parakeet (Cyanoramphus malherbi) or, in Māori, kākāriki karaka, is a small parrot endemic to New Zealand. In New Zealand it is always known as the orange-fronted parakeet, a name it shares with a species from Central America, while in the rest of the world it is known as Malherbe's parakeet.
