when was te reo made an official language
Māori language Māori (/ˈmaʊri/; Māori pronunciation: [ˈmaːɔɾi]  listen), also known as te reo ("the language"), is an Eastern Polynesian language spoken by the Māori people, the indigenous population of New Zealand. Since 1987, it has been one of New Zealand's official languages. It is closely related to Cook Islands Māori, Tuamotuan, and Tahitian. The number of speakers of the language has been in sharp decline since the end of World War II, despite a language revitalization effort.[4]
