I think you're talking about something different.

My context is discriminatory urban zoning (à la exclusionary zoning or redlining in the US).

I am not sure there are any examples of that for urban zoning in New Zealand. Please enlighten me if you know better.

I agree there is plenty of history of terrible treatment of maori and their land in NZ, but that is a different topic and not relevant. I admit I am ignorant about the history of urban planning in NZ.
