There are “Part Breed” Including some Maori genetics with various degrees of Maori ancestry.
Then there are also those who Identify as Maori, eg Willie Jackson, Marama Davidson, and Debbie two Dads, who incidentally until the addition of the Barcode did look certifiably Pakeha.

Now I am, and I identify as of Celtic origin, afaik all my ancestors came to the colony from various parts of Scotland.
There are hints there may be some Blood from northern France in one link never verified.

I have one identifiable trait that has become apparent in later life with Dupuytren’s syndrome causing claw like contraction in my left hand that I am informed only comes with a Celtic genetic link.

Is it ever to become policy, the links to health wealth and genetic outcomes will be rated by actual degrees of Maoriness and not the one size fits all who identify as Maori.

Should the wet dreams of the racists ever come to fruition and the Maori Parliament sits as a Senate style second Chamber will the citizenry be able to en mass, decide to identify as “Maori” to subvert the apartheid notions into irrelevance or will there become a desperate need to have a “Commission” to bequeath the degree of Maoriness in a direct biological sequence for all, a sort of “Nuremberg Law Committee” if you will.
