Kia ora
Kia ora is a Māori language (known as Te Reo) greeting which has entered New Zealand English. It means literally "be well/healthy" and is translated as an informal "hi" at the Māori Language Commission website Kōrero Māori. It is also used as a farewell and thanking someone as well. The New Zealand Ministry for Culture and Heritage website NZ History lists it as one of 100 Māori words every New Zealander should know, with a definition "Hi!, G'day! (general informal greeting)".
