The Boundaries Commission has announced proposed changes to electorate boundaries:
“Where possible the current boundaries have been retained to minimise the number of people affected by electorate boundary and name changes. Of the 71 existing electorates, 36 are unchanged. The adjustments in other electorates reflect changes in population since 2014 when the boundaries were last reviewed,” says Representation Commission chair Judge Craig Thompson.
The biggest areas of change are in the Auckland region, Christchurch, and Otago and Southland. . .
North Island general electorates
- Rodney is redrawn to include Dairy Flat and Coatesville, and renamed Whangaparāoa
- Helensville is extended into Northland, Rodney (now Whangaparāoa) and Upper Harbour, and loses the Waitakere Ranges to New Lynn
- The addition of population to New Lynn from the north means changes are also required to Mt Roskill, Maungakiekie, Manukau East, and Manurewa
- Flat Bush is created by drawing population from the existing electorates of Hunua, Manurewa and Papakuraand includes Wattle Downs and Takanini
- Population from Waikato is added to Hunua which is renamed Port Waikato. Adjustments are also made to the boundaries of Waikato with Coromandel, Hamilton West and Taupō
- Adjustments are also made to the boundaries of Whangarei and Bay of Plenty
South Island general electorates
- Brightwater is moved from Nelson to West Coast-Tasman
- Selwyn is redrawn and no longer includes Banks Peninsula. Adjustments are also made to Ilam, Wigram, Port Hills (renamed Banks Peninsula), Christchurch East and Rangitata
- Clutha-Southland gains the Alexandra and Clyde area from Waitaki
- Otago Peninsula is moved from Dunedin South to Dunedin North, and South Otago is added to Dunedin South from Clutha-Southland
- Winton and The Catlins are added to Invercargill from Clutha-Southland.
Few if any of these changes are unexpected.
In the south, Dunedin South might be regarded as a little more marginal, Invercargill will probably be a bit bluer and Dunedin North will still be red.
Clutha Southland and Waitaki will cover a little less area, still be larger than some countries, and still be blue.
Banks Peninsula will be a bit bluer than the Port Hills one it replaces.
- Tāmaki Makaurau gains an area around Te Atatū South from Te Tai Tokerau and an area in East Manurewa from Hauraki Waikato
- A minor adjustment between Ikaroa-Rāwhiti and Te Tai Tonga is made in Naenae.
Names of electorates
Four electorate name changes are proposed: Rodney to Whangaparāoa, Hunua to Port Waikato, Rimutaka to Remutaka and Port Hills to Banks Peninsula.
The proposals create one new general electorate bringing the total number of electorates to 72: 16 general seats in the South Island, 49 in the North and seven Maori seats.
That will mean one less list seat – 48, down 12 from the 60 when MMP was introduced.
The number of seats in parliament is set at 120 (unless there’s an overhang) and the number of South Island seats is set at 16.
After every census the South’s population is divided by 16 to set the number of people per seat plus or minus 10%. The North’s population is growing faster than the South’s which is why it keeps getting an extra seat. That is likely to continue and it enough more people opt for the Maori roll rather than the general one, another Maori roll would result in the loss of another list seat.
Politik asks if there’s too many South Island seats.
There are not, there are too few.
Clutha Southland and Waitaki, the biggest and third biggest general electorates are getting a little smaller but are still far too big geographically and proposed changes will make West Coast Tasman, the second biggest general electorate, even bigger. They’re all bigger than all but one of the Maori electorates, Te Tai Tonga, which covers the whole of the South Island, Stewart Island and a bit of Wellington.
The difficulties of servicing electorates as large as these mean no matter how good their MPs are, they can’t possibly give their constituents the same attention that those with smaller electorates do.
If MMP’s proportionality is to be maintained, the number of MPs will have to be increased and I’d argue for at least one more South Island electorate to make the bigger ones a little more manageable.
