This is such a strange thing to require someone to know, especially when she doesn’t deal with Maori land, and all sale is the same legally regardless of the ethnicity of the buyer. And the justification given for making this mandatory is incredibly tenuous, in my view.
Its not reasonable because Maori worldview is pretty normal to anyone in nz. Maybe it differs if you are buying and selling maori land since there might be ritual customs but she isn’t. Maori are normal people and no one treats them any different except our racist government who treat them like they’ve just discovered a new species.
