Consumers in 14 regions around the country can expect to pay more for their electricity, as a result of an overhaul of pricing for the national grid.
But this also means good news for 15 other regions who should pay less under the proposed changes.
The Electricity Authority (EA) has released its preferred option for a fairer way of paying for the national grid. Access to the grid, provided by state-owned monopoly Transpower, makes up about 10 per cent of the average household power bill.
Under the EA's preferred option, released on Tuesday morning, some regions will have to pay more for the benefit of better infrastructure. The overall impact on residential prices would be an increase of 0.5 per cent, or $11 per household per year.
The biggest increases would be worn by those in Auckland, Northland, Ashburton and the West Coast.
Lower prices: Invercargill, South Canterbury, Central Otago and Dunedin, Hawke's Bay, East Coast, Queenstown, North Canterbury, Marlborough, Tasman, Christchurch, Western BOP/Taranaki, Tararua, Southland, Rotorua, Waikato North, Wellington.
Higher prices: Ashburton, West Coast (Westport), South Auckland, Eastern BOP, Waitaki, Whangarei, Waikato, Northland, Auckland, West Coast (Hokitika).
No change, or not yet clear: Horowhenua, Otago, Hamilton.
