Late in 2017 Councillors in five regions voted, without seeking prior public approval, to establish separate Maori wards. As a result, dedicated locals, supported by Hobson's Pledge, were forced to collect the required number of signatures to force binding referenda to see what the public actually thought. And the results were clear: the public rejected race based wards in Palmerston North (68.8%), Western Bay of Plenty (78.2%), Whakatane (56.4%), Manawatu (77%), and Kaikoura (80%).
Since then, Hastings District and Otago Regional Councils circumvented public opinion by appointing Maori with voting rights to Council committees.
But it is expensive and time consuming to gather signatures for referenda, and very difficult to challenge Council appointees. The best way to avoid creating a Council that treats its citizens as members of a particular ethnicity (which apparently are all alike and think the same way), rather than as individuals, is to vote for candidates who reject racial separatism.
