How do you say 1998 in maori?

There isn't a direct translation for 1998 in Māori. Māori traditionally used a system based on generations and lunar cycles rather than a precise year system like the Gregorian calendar.

However, you could say "Kotahi mano iwa rau iwa tekau ma waru" which literally translates to "One thousand nine hundred ninety-eight".

It's more common to refer to years using the Gregorian calendar system in Māori, so you would usually just say "Nineteen ninety-eight".
