It is an offical language of NZ, & the original language, more speakers would help it from flourishing and not dying out

Learning a second language is beneficial to the development of children. It would help NZers to have a deeper cultural understanding of Te Ao Māori & tan hats when ya and this would promote more empathy towards Māori in general. If people have increased empathy toward those that are at a general disadvantage in wellbeing outcomes/statistics then they would be more open to supportive positive change.
