Cook Islands Māori is an Eastern Polynesian language that is the official language of the Cook Islands. Cook Islands Māori is closely related to New Zealand Māori, but is a distinct language in its own right. Cook Islands Māori is simply called Māori when there is no need to disambiguate it from New Zealand Māori, but it is also known as Māori Kūki 'Āirani (or Maori Kuki Airani), or, controversially, Rarotongan. Many Cook Islanders also call it Te reo Ipukarea, literally "the language of the Ancestral Homeland".
