Formal:
* "Kei te pai ahau, tēnā koe." (This literally translates to "I am well, thank you.")
* "Kei te pai ahau, mihi." (This means "I am well, thanks.")
Informal:
* "Āe, pai ahau." (This translates to "Yes, I'm good.")
* "Kei te pai." (This simply means "I am well.")
Remember that Māori is a very respectful language, so it's best to use a more formal greeting when speaking to someone you don't know well.
