New Zealand election 2026: Which parties have plans to lower electricity costs?

For a renting couple whose work hours and pay change from week to week, electricity affordability is about more than the average annual bill. It is also about whether you can manage a high bill in a low-income week, and whether a policy would reduce what you actually pay at home.

As you consider your vote in New Zealand's 2026 general election, there are three things worth separating:

• Lowering the price of electricity: reducing the cost of generating, transporting or retailing power.
• Reducing your household bill: discounts, rebates or cheaper electricity plans that lower the amount you pay.
• Making bills easier to manage: payment flexibility, better access to cheaper tariffs and help when income falls unexpectedly.

These approaches aren't interchangeable. A policy can improve the electricity market over time without making next month's bill any easier to afford.

I'll compare the parties' documented proposals and distinguish between what has evidence behind it, what is plausible but uncertain, and what would depend on how a policy is implemented. Because the election is in 2026, it is also important to distinguish an existing government policy from a new election promise.

1. What the main parties are proposing

The policies below are those publicly documented as of 16 October 2026. The election is scheduled for 7 November 2026. These are proposals and party claims, not guarantees of future savings. The main parties vying to form New Zealand's next governmentElection policy tracker: what the parties are promising

National — more supply and competition

Policy: Electrify NZ 2.0

National proposes faster construction of renewable generation, more private investment in transmission, easier electricity connections, more competition in solar buy-back rates and a Home Energy Fund offering long-term, low-interest loans. It also wants affordability to be an explicit objective for the Electricity Authority. Affordable power Kiwis can rely onAffordable power Kiwis can rely on

How it could help: More generation and better competition could reduce wholesale costs over time. Easier solar connections and home-energy loans could help some households reduce their bills.

Main limitation for renters: A loan for solar panels or batteries is not the same as a lower bill next month. You would need to check the fund's eligibility and whether your rental property qualifies.

Labour — solar support and consumer protection

Policy: SolarSaver and price-gouging rules

Labour proposes government-backed, low-interest finance for solar and batteries, up to $3,000 in extra support for eligible low- and middle-income households, and plug-in solar options for renters. It estimates a typical household could save around $1,000 a year with its solar programme. Labour also proposes making electricity overcharging illegal and requiring companies found to have overcharged customers to pay them back. Labour's Cost of Living PlanPower Prices for 2026

How it could help: The renter-specific solar proposal is directly relevant if you cannot install a permanent rooftop system. Stronger enforcement could also help if excessive pricing is established.

Main limitation: The $1,000 annual saving is a party estimate, not a guaranteed saving for every household. The price-gouging proposal would require rules defining unlawful overcharging and evidence that a company breached them. Solar also depends on suitable installation, sunlight, electricity usage and landlord or building arrangements.

Green Party — a publicly owned electricity company

Policy: Kiwipower

The Greens propose creating Kiwipower, a publicly owned entity to invest in renewable generation and backup capacity. Their package also includes zero-interest clean-energy loans, investment in community energy, solar on more public housing, fairer solar export payments and a renters' right to solar. Power for all of usGreen Party launches plan to cut power bills and take power back from the big energy companies

How it could help: Public investment could fill gaps in electricity supply that private investors do not address, while community energy and solar support could broaden access to cheaper generation.

Main limitation: Establishing a new public generator would take time and money. Its effect on retail bills would depend on how much additional capacity it built, its financing costs, and whether the benefits were passed through to customers. Zero-interest loans help only if you can access and use them.

ACT — private investment and fewer bottlenecks

Policy: Competition and infrastructure reform

ACT proposes more private investment in electricity generation and transmission, more competition for network connection work, freedom to sell household-generated electricity to different retailers, and scrutiny of expensive network upgrades where batteries or demand management might be cheaper. It supports making it easier to develop new generation and maintaining access to gas for backup supply. ACT New Zealand

How it could help: Competition and lower-cost infrastructure could reduce the costs of delivering electricity and make it easier for new generators to enter the market.

Main limitation: More investment does not automatically mean cheaper retail tariffs. Savings depend on whether new entrants compete effectively and whether network savings reach households.

New Zealand First — split up the major power companies

Policy: Power to the People

NZ First proposes separating the major generator-retailers so that the same companies do not control both generation and retailing. It also proposes a National Energy Strategy, long-term fixed-price contracts for new generation, measures to address withheld supply, and equal-price buy-back for household solar exports. "Power to the People" - Winston Peters - State of the Nation 2026Our PolicyPower Prices for 2026

How it could help: Separating generation and retailing could make it easier for independent retailers to compete and could reduce some conflicts of interest.

Main limitation: Restructuring the industry would be complex. Separation alone would not create more electricity or remove rising network costs, and the impact on retail prices would depend on the details of the new market.

These parties' approaches are different, but they share a stated aim of making electricity more affordable. The key difference is whether they rely mainly on private investment and competition, household assistance, or a more substantial restructuring of the market.

2. What does the evidence say about whether these plans would work?

The best way to assess the promises is to look at what is already happening in New Zealand's electricity market, and what research can and cannot establish.

REAL-WORLD PRICE PRESSURE

6.8%

Average increase in electricity prices across households and small businesses in the first half of 2026, following an 8.0% rise in 2025. Among households that experienced a price change, the average increase was 8.7%. Data shows 6.8% increase to power bills across households and small businesses

A MAJOR DRIVER

54%

Of the reported increase in 2026 prices was attributed to higher electricity network charges. Those costs cover the infrastructure needed to transmit and distribute power.

AN EXISTING WAY TO SAVE

About $82

The Electricity Authority reported that people who initiated a switch using its Billy comparison service saved an average of around $82 for that month. This is an observed average, not a guaranteed recurring saving for every household. Data shows 6.8% increase to power bills across households and small businesses

Evidence by policy type

Policy approach	What the evidence supports	What remains uncertain
More electricity generation	More supply can ease scarcity and reduce wholesale-price pressure, all else being equal.	How quickly new generation comes online, what it costs to build, and how much lower wholesale costs flow through to household bills.
Breaking up generator-retailers	Independent retailers can provide more competition if they have fair access to wholesale electricity and risk-management contracts.	Whether a structural split would produce lower total costs, and how transition costs or new market arrangements would affect bills.
Solar panels and batteries	Generating electricity at home can reduce purchases from a retailer, particularly when solar output coincides with household demand.	The upfront or financed cost, access for renters, export payments, and the savings achievable at an individual property.
More public ownership	A public entity could invest in generation and backup capacity to meet longer-term supply needs.	Whether it would build additional capacity more cheaply or reliably than alternatives, and whether its benefits would lower retail prices.
Regulating lines charges	Regulatory oversight can constrain the revenue network companies are allowed to recover.	How much further savings are possible without compromising maintenance, reliability and necessary network upgrades.

These are established economic mechanisms, not proof that any one party's complete programme will achieve its advertised savings. The Electricity Authority and Commerce Commission provide useful evidence on current prices, competition and network costs.

An important example: competition reforms are already being tested

From 1 July 2026, large electricity retailers have been required to offer plans with cheaper off-peak electricity. New rules also aim to improve access to wholesale risk-management contracts for independent retailers, making it harder for large generator-retailers to favour their own retail businesses. Off-peak pricing to make power more affordableElectricity Authority to level electricity competition playing field

This is important because it shows that some market reforms are already being implemented, rather than being promises that only one party could introduce.

However, there is a catch for people working changing shifts: time-of-use pricing only saves you money if the cheaper periods fit your actual electricity use. If you have to heat the home, cook or do laundry during expensive peak periods, the wrong plan could leave you no better off. Compare the whole tariff, including daily fixed charges, rather than just the advertised off-peak rate.

Network charges are another complication. The Commerce Commission says transmission and distribution account for just over 30% of an average power bill, with these costs expected to keep rising until at least 2030. Much of that reflects investment in replacing ageing infrastructure, resilience and accommodating growing demand. Understanding why changes to lines charges may impact your electricity bill

That means even if a government succeeds in bringing down wholesale electricity prices, the total bill may not fall by the same amount.

3. Which policies address your situation as renters with variable pay?

For your circumstances, it helps to distinguish policies that might lower the cost of power over several years from policies that help when your pay is short this week.

1. More predictable bills and fewer surprises

Look for policies on clearer bills, appropriate payment plans, protection from unexpected back-billing and help when customers struggle to pay. These measures can matter even if the unit price of electricity does not change.

The Electricity Authority has already adopted rules requiring retailers to check customers' plans regularly and limiting back-bills to six months, although implementation of the updated billing rules has been deferred to 1 April 2027.

2. Lower bills without needing a large upfront payment

Labour's proposed renter-accessible plug-in solar support is directly relevant to investigate, while broader solar-loan schemes may be less useful if you cannot install equipment at a rental. Check whether support is a grant or a loan, who qualifies, and whether you need your landlord's permission.

For a household with irregular pay, financing equipment creates a further commitment, so projected electricity savings should be compared with the repayments.

3. Lower ongoing electricity prices

National and ACT emphasise investment and competition; NZ First proposes separating generation from retailing; the Greens propose Kiwipower; and Labour combines household solar support with consumer-protection measures.

These approaches could influence the size of your bill, but their longer-term results are uncertain. None should be treated as a guaranteed reduction in your next bill.

4. How to assess the promises before voting

When you read a party's policy or a claim about savings, ask these four questions:

• How much would we actually save? Is the figure an independently measured result, a modelled estimate, or a campaign projection?
• When would the savings arrive? Is this a direct discount or assistance measure, or does it depend on infrastructure being built and market changes occurring?
• Can renters access it? Check whether it requires home ownership, a landlord's consent, a loan or a contribution of your own.
• Would it help during a low-pay week? A lower average annual bill is useful, but it does not necessarily make payments more manageable when rostered hours drop.

For a fair comparison, look for a policy's estimated cost, funding source, eligibility rules, implementation timetable and independent assessment. Those details are what turn a broad promise into something you can evaluate.

5. Steps you can take now, regardless of the election result

You don't need to wait for a new government to see whether your current electricity costs can be reduced.

• Compare your existing plan with other offers through the Electricity Authority's Billy comparison and switching service. Check the daily charge, usage rates, discounts and any conditions on special offers.
• Ask your retailer whether it offers a payment arrangement that follows your variable income, or whether smoothing payments across the year would suit you. Check how any credit or debt balance is handled.
• If you are struggling to pay, contact the retailer early and ask about its hardship support and options to avoid disconnection.
• Check the Citizens Advice Bureau if you need help understanding your rights or discussing an electricity bill.

The Electricity Authority's evidence suggests that comparing plans can deliver a real, immediate benefit for some households, although your own result will depend on your usage and location.

Bottom line

The central question is not just which party says it will make electricity cheaper. It is which combination of lower costs, accessible household support and payment protections would make your household budget more resilient.

For you and your partner, I would pay particular attention to whether a policy:

1. Reduces bills without requiring you to own your home.
2. Offers measurable savings rather than relying only on future market changes.
3. Helps people manage payments when income varies from week to week.

Those criteria let you compare the parties' proposals without assuming that any campaign's promised savings are certain.
