Nine districts have this year voted in favour of Māori wards, including Gisborne District Council.
The decision was welcomed by tangata whenua. However, Gisborne Mayor Rehette Stoltz said the decision will now go to a referendum.
"Now that we have voted to establish Māori wards in time for the 2022 and 2025 elections we will have to do a representation review," Stoltz said. "That will tell us how our wards will look, how many councillors will be in the general ward and how many councillors will be in the Māori ward."
However, if 5 per cent of registered voters sign a petition demanding Gisborne Council hold a referendum on the Māori wards, the council must allow that to happen. Previously, referendums have almost always stopped Māori wards because majorities tend to vote against improvements for minorities.
Referendums can also be demanded for changes to voting methods but not if a council chooses to change general wards.
