I came across this question on Breaking Views NZ:

Can companies legally use Māori names?

An interesting question if only because there is no such thing as “Maori names”. There won’t, indeed can’t be until someone invents a set of symbols representing sounds for “maori”.

Until then, if you use the alphabet (rather than, for example, the futhark) no words are anything other than universal, using the same 26 letters in varying orders and numbers.

There are words pretending to be in maori language but that is not the question asked.

As “maori” have started using those alphabet letters without formal permission I suggest a charge to “maori” of $1 per letter used by “maori” (including all 89,436 versions of “The Treaty”) since 1840.
