So Mallard thinks Pakeha are indigenous to NZ does he?

I guess he’s going from the dictionary definition. Which is fine, as long as
he isn’t trying to imply that they still aren’t bound by the Treaty.
Personally when I think indigenous I think of the UN definition

“Indigenous communities, peoples and nations are those which, having a
historical continuity with pre-invasion and pre-colonial societies that
developed on their territories, consider themselves distinct from other
sectors of the societies now prevailing in those territories, or parts of
them.”

Which is what Maori are and will always be, and pakeha will never be in NZ.
