Energy Minister Simeon Brown says there is no single solution to New Zealand's high electricity bills, with the Government now examining whether changes to the regulation of power distribution companies could put downward pressure on prices. Network charges for poles, wires and substations make up around a quarter of household power bills and have accounted for two-thirds of recent increases.

Government Targets Rising Power Bills
The Ministry of Business, Innovation and Employment has released a discussion document examining whether legislative changes are needed to make New Zealand's electricity distribution sector more efficient and affordable.
Brown told Morning Report he was also seeking advice from electricity generator-retailers and the Electricity Authority about what could be done to tackle higher household power bills.
But he cautioned there was "no silver bullet" capable of solving the problem.
The minister said focusing solely on wholesale electricity prices overlooked another significant contributor to household bills: electricity distribution companies.
Network Charges Behind Much of Recent Increase
Network charges cover infrastructure such as substations, poles and power lines and account for approximately a quarter of household electricity bills.
According to Brown, those charges have accounted for two-thirds of recent power price increases.
Brown said wholesale electricity prices had fallen and the Government expected the major electricity companies to pass those reductions through to consumers.
At the same time, he argued greater scrutiny was needed across the other components contributing to electricity prices.
28 Electricity Distribution Businesses
New Zealand has 28 Electricity Distribution Businesses, or EDBs, responsible for operating local electricity infrastructure.
Some are already subject to price-quality regulation, under which the Commerce Commission determines maximum revenues and minimum service standards.
Brown said regulated revenues were last established in 2024, when interest rates had risen substantially following the inflation surge.
Consumers were now paying for the effects of those higher financing costs alongside the expense of preparing electricity networks for increased electrification and future demand.
Are Natural Monopolies Being Regulated Enough?
Brown described electricity distribution companies as "natural monopolies" and argued the Commerce Commission does not currently have all the powers required to regulate them effectively.
One proposal contained in the discussion document is a price-quality regime covering all line companies, intended to ensure customers receive a fair deal while creating downward pressure on costs.
Brown has also called for money collected through power bills to be ringfenced in a similar manner to water infrastructure funding, helping ensure revenue paid for electricity networks is reinvested into the infrastructure customers are paying to use.
In a media statement, Brown said distribution companies needed to "come to the affordability party."
Three Areas Targeted for Reform
The Government has identified three key areas where it believes further action could improve the performance of electricity distribution businesses:
- Collaboration and standardisation
- More responsive economic regulation
- Stronger governance and accountability
Brown said electricity costs and the prospect of further increases remained front of mind for New Zealand households and businesses.
He expects the electricity sector to improve efficiency, including through greater collaboration and standardisation.
"Positive work is underway, but more change is needed to make the system more affordable for households and businesses," Brown said.
Cost of New Zealand's Energy Transition
Commerce and Consumer Affairs Minister Cameron Brewer has also raised questions about the scale of investment required as New Zealand moves toward greater electrification.
Brewer said the investment needed for the country's energy transition raised the question of whether existing arrangements would continue delivering the best outcomes for consumers.
That creates a difficult balance.
Electricity networks need significant investment to maintain existing infrastructure while simultaneously preparing for greater electricity demand. But ultimately those investment costs can flow through to households and businesses through their electricity bills.
The Government's challenge will be ensuring necessary infrastructure investment does not remove incentives for network operators to control costs.
Public Consultation Open
The Government is now seeking public submissions on the proposed changes.
The MBIE discussion document and consultation process are available HERE.
The consultation will examine options intended to strengthen the performance of electricity distribution businesses while maintaining reliable services, supporting increased electrification and improving affordability.
For households already dealing with higher living costs, however, the immediate issue remains straightforward: whether regulatory reform will ultimately translate into lower electricity bills.
