* Kia ora: This is the most common and versatile greeting, suitable for both formal and informal settings. It literally means "be well" and can be used to say "hello", "goodbye", or "thank you".
* Tena koe: This is a more formal greeting, used when addressing someone with respect. It literally means "Greetings to you".
* Māori: This is a more informal greeting, often used between friends. It literally means "Maori", but it's used in a similar way to "hey" in English.
So, to say "hello" to one person in Maori, you could use any of these greetings, depending on the situation.
For example:
* Kia ora, John! (Hello, John!)
* Tena koe, Mrs. Smith. (Greetings to you, Mrs. Smith.)
* Māori, bro! (Hey, bro!)
