The electorate boundary review released its proposed changes to New Zealand’s electorates ahead of the 2020 election last November.

At the beginning of this year, the commission received more than 300 complaints over the proposed changes.

The objectors included the Labour Party, which companied about the boundary changes of Tāmaki Makaurau, Manukau East, Manurewa, Flat Bush, Christchurch East, Dunedin North and Invercargill and the ACT party that complained about the Epsom electorate, where its one MP and leader David Seymour holds.

Chair of the Representation Commission Judge Craig Thompson said they had made no changes to 36 electorates.
