What does wai tou mean in maori?

"Wai tou" is not a phrase in the Māori language. It's likely a misspelling or a combination of words that don't have a common meaning together.

It's possible you are thinking of one of these words:

* Wai: This means "water".

* Tō: This means "your" (possessive pronoun).

* Tau: This can mean "year" or "season".
