How does the Māori language play a role in preserving New Zealand's indigenous culture?

For many years, the use of te reo Māori was in decline as a result of colonization and government policies that suppressed the language in schools and public life. However, in recent decades, there has been a resurgence of interest in the Māori language, and it is now taught in many schools across New Zealand. Moreover, efforts by the government, educational institutions, and native speakers have contributed to a renewed enthusiasm for learning and preserving the language. Initiatives such as Te Wiki o te Reo Māori (Māori Language Week) and the establishment of Māori-language immersion schools have significantly contributed to the revitalization of te reo Māori.
