For the disagree-r, the United Tribes of New Zealand was a native New Zealand tag that claimed (and was working on) sovereignty over all of NZ in the period. It had founding documents and legal status. Just as France is the best formable for Orleans and Gascony in EUIV rather than some made up word, United Tribes would be the best choice for a Māori (i.e. “native New Zealander”) formable.
“Aotearoa” is a Māori word that’s been wedged into a western concept that was never a country or political unit, has never been proposed as anything except a name for modern westernised New Zealand, and makes no sense whatsoever as a tag in any game.
It doesn’t even make sense for a unified New Zealand; historically “Aotearoa” refers to the North Island, and possibly even just the north of the island, not all of New Zealand.
If Māori tags
have to have a formable it should be the United Tribes. If they must have one that isn’t on the map in 1836 then “Maoridom”, since at least they all identified as Maori, would be infinitely preferable to “Aotearoa”, which is essentially a made up word. One may note that when the Kīngitanga crowned a Māori monarch in 1858 he was called the Māori King, not the King of Aotearoa or anything else. Note also that many other states around the world take their names from their people, not from an ambiguous indigenous word for parts of their landscapes.
I understand and appreciate the desire to represent Māori and other indigenous peoples out of a willingness to give them equal respect and attention with, say, European peoples.
But, representation that gets it wildly wrong or representation that forces their Māori-shaped peg into Western-shaped holes is at least as disrespectful as no representation at all.
Insisting on an “Aotearoa” formable because it’s “cooler” than the real polities and real efforts of Māori reduces Māori to a source of “cool”—and is intensely disrespectful, a sort of cultural imperialism.
