Why "ai"?

I can’t quite get my head around when/why/how to use ai in Māori grammar.

It seems to be a tag in verb-based phrases that signifies the end of a particular part of the sentence.

It’s always in some questions such as Ā hea …. ai? but only sometimes in responses.

For now, i’m definitely just including it in my sentence constructions based on gut feel!
