However, you can use a few options depending on the context:
* "Whutupōro" is the most common term used, literally meaning "ball game". This is the most widely accepted term for rugby in Māori.
* "Rukapī" is a phonetic spelling of "rugby" and is sometimes used, though it's not as common as "Whutupōro".
* You could also use "Hīkoi pōro" which literally means "ball game". This is a less common term, but it's still understandable.
So, the most accurate and common way to say "rugby" in Māori is "Whutupōro".
