2026 New Zealand election: which parties have a plan to lower electricity bills?

For someone renting with a partner and working variable rostered hours, electricity prices are more than an inconvenience. Your income can fall in a particular week, but your power bill still arrives. A policy that makes electricity cheaper, more predictable and easier to budget for could make a real difference.

There are three important things to look for when comparing parties:

1. Lower total costs: Will the policy actually reduce the amount households pay, rather than just change how electricity is generated?
2. More predictable bills: Will it reduce exposure to price spikes and seasonal increases?
3. Who benefits: Will renters and ordinary households see the savings, or will most of the benefits go to businesses, homeowners or electricity generators?

One important distinction: electricity generation costs, wholesale prices, network charges and retail-company margins all contribute to your final bill. A policy that tackles only one of these does not necessarily mean a substantial reduction in household bills.

1. What the main parties are proposing

The following reflects published election commitments available by 21 October 2026, rather than older policies already in place. Party energy policies, side by sideThe politics of power: Comparing energy policies ahead of Election 2026

National – increase supply and competition

Market-led approach

National's Electrify NZ 2.0 proposes:

• Making it easier and faster to build wind, solar, geothermal and other generation.
• Encouraging private investment in electricity generation and transmission.
• Improving competition between electricity retailers.
• Allowing households with solar panels or batteries to sell surplus electricity to whichever retailer offers the best price.
• Introducing low-interest, long-term loans through a Home Energy Fund.
• Making affordability an explicit objective for the Electricity Authority.
• Improving backup electricity supplies for dry years.

Would it work?

There is a sound economic argument for building more electricity generation. More supply can reduce wholesale prices, particularly when electricity is scarce.

National also has a reasonable argument for improving competition and making it easier to connect new generators.

The limitation is timing. New power stations and transmission infrastructure take years to build. And cheaper wholesale electricity does not automatically mean cheaper retail bills.

The Electricity Authority reported that wholesale contract prices had been falling in 2026, but household electricity prices were still increasing. Affordable power Kiwis can rely onData shows 6.8% increase to power bills across households and small businesses

Official policy: National – Electrify NZ 2.0.

Labour – solar power, subsidies and consumer protection

Direct household support

Labour's main proposal is its $160 million SolarSaver programme.

It includes:

• Government-backed, low-interest finance for household solar and batteries.
• Subsidies of up to $3,000 for eligible low- and middle-income households.
• Plug-in solar panels for renters.
• A $30 million community battery fund.
• Better payment for households exporting surplus electricity.
• Stronger Commerce Commission powers to investigate excessive pricing by companies with significant market power.

Labour estimates that a two-panel plug-in solar system costing around $1,500 could save renters $300–$400 annually.

It also proposes allowing renters to access subsidies, rather than restricting household energy assistance to property owners. Labour's SolarSaver

Would it work?

There is some particularly relevant evidence behind this approach.

• Germany has around 1.5 million registered plug-in solar systems.
• Community solar and battery projects are already operating in New Zealand.
• EECA research finds that residential solar can deliver worthwhile financial returns under suitable conditions.

However, Labour's estimated renter savings are projections, not guaranteed savings. They will depend on sunlight, electricity consumption during daylight hours, installation costs and the rules governing plug-in solar.

There is another important limitation: solar reduces the amount of electricity you buy, but it does not eliminate fixed daily charges or network costs.

For renters, this is nevertheless one of the more directly relevant proposals in the election.

Official policy: Labour – SolarSaver.

Green Party – public ownership and renewable electricity

Greater government involvement

The Greens propose establishing Kiwipower, a publicly owned electricity company.

Its purpose would be to invest in renewable generation and provide backup electricity when hydroelectric storage is low.

Other commitments include:

• Zero-interest loans covering up to 90% of eligible household clean-energy investments.
• A right to solar for renters.
• Legalising plug-in solar.
• $200 million for community-owned renewable energy.
• Solar panels on more than half of public homes within four years.
• $80 million for renewable energy projects for Māori housing.
• Expanding the Warmer Kiwi Homes programme.

The Greens oppose the proposed LNG import facility, favouring renewable generation and alternative backup solutions. Green Party launches plan to cut power bills and take power back from the big energy companiesPower Prices for 2026

Would it work?

There is a credible case for investing in renewable electricity and publicly owned infrastructure.

New Zealand already generates most of its electricity from renewable sources. The challenge is making sure enough electricity is available when rainfall is low, hydro storage is depleted or demand is particularly high.

Kiwipower could address gaps in investment that private generators do not consider attractive.

But public ownership does not automatically mean lower prices. The cost of building generation, batteries and backup capacity still has to be paid for.

The important unanswered question is how Kiwipower would be funded, governed and required to demonstrate that its investments actually lower household prices.

Official policy: Green Party – Power for all of us.

ACT – private investment and lower network costs

Competition-focused

ACT's September 2026 policy focuses on:

• Encouraging private investment in electricity generation.
• Allowing private companies to build and operate additional transmission infrastructure.
• Letting households sell their solar electricity to different buyers.
• Allowing accredited contractors to compete for electricity connection work.
• Requiring electricity networks to properly consider cheaper alternatives, such as batteries and demand management, before expensive infrastructure upgrades.

ACT opposes breaking up the large generator-retailer companies.

Would it work?

Some proposals have a strong economic rationale.

In particular, allowing batteries and smarter technology to compete with traditional network upgrades could save money.

Competition in connection work could also reduce costs for new developments and generators.

However, these measures are mostly about improving the efficiency of the electricity system. They do not necessarily produce immediate reductions in existing household bills.

ACT's own policy acknowledges that local distribution networks are monopolies, which means regulation remains important.

Official policy: ACT – Stability, investment, affordability.

NZ First – break up the major electricity companies

Major structural reform

NZ First proposes splitting the major electricity companies into separate generation and retail businesses.

Its argument is that the four major generator-retailers have too much control over the market.

Other proposals include:

• Changing the wholesale electricity pricing system.
• Preventing companies from withholding supply to push prices up.
• Providing long-term fixed-price contracts for new electricity generation.
• Allowing households with solar to sell electricity back at the same price they pay for electricity.

Would it work?

The theory is that separating generation and retail businesses would make it easier for independent retailers to compete.

That could put downward pressure on retail prices.

But there is a significant question about whether splitting the companies would actually reduce generation costs.

Breaking up companies does not itself create additional electricity, and structural changes could create disruption and uncertainty for investment.

ACT disputes the need for this approach, arguing that the underlying problem is insufficient supply and backup generation rather than the structure of the large companies. Breaking up the Gentailersassets.nationbuilder.com

Official policy: NZ First – Breaking up the Gentailers.

2. What about the other parties?

Two other parties worth including in your comparison are:

• Te Pāti Māori: Its Energy Sovereignty policy proposes a $1 billion fund to expand Māori and community ownership of renewable electricity. The aim is to retain more economic benefits within communities and increase local energy independence.
• The Opportunity Party (TOP): Its energy proposals include a cross-party commitment to add 30 GW of renewable generation by 2050, reinvesting government profits in renewables and offering low-interest loans for household electrification.

These approaches have potential, but their impact on your immediate household electricity bill is less certain.

3. What does the independent evidence actually tell us?

This is arguably the most important part of deciding which promises to believe.

Electricity bills have several components

Illustrative breakdown – actual proportions vary by household and region.

Network charges – just over 30%

Transmitting and distributing electricity to your home.

Generation and wholesale electricity

The cost of producing and purchasing electricity.

Retailing and other charges

Retail operations, metering and other costs.

Network share based on the Commerce Commission's description of average household bills. Understanding why changes to lines charges may impact your electricity bill

There is a particularly important finding from the Electricity Authority.

6.8%

Average power price increase in the first half of 2026

Across households and small businesses, following an 8% increase in 2025.

54%

Of the 2026 increase came from higher network charges.

This shows why simply promising more generation or breaking up electricity companies may not be enough.

Data shows 6.8% increase to power bills across households and small businesses

The Commerce Commission explains that network costs are increasing because infrastructure needs repairing, replacing and expanding. These increases are expected to continue, although more gradually, through to 2030. Understanding why changes to lines charges may impact your electricity bill

Evidence for the different approaches

Policy approach	Evidence assessment
Building more generation	Strong economic rationale, but benefits take time
More competition between retailers	Credible, but depends on effective market rules
Household solar	Supported by NZ research, but depends on household circumstances
Community batteries	Promising, with local examples
Publicly owned generation	Potentially effective, but depends on investment and governance
Breaking up electricity companies	Uncertain; no guarantee of cheaper bills
Reducing network costs	Important, but savings depend on regulation and infrastructure decisions

One particularly useful independent study is EECA's research into residential solar.

It used real electricity consumption data from almost 50,000 homes across four New Zealand cities.

It found that:

• Solar is financially viable for a significant proportion of households.
• Households using electricity during daylight hours tend to benefit most.
• Batteries can improve returns, but their cost remains a barrier.
• Financial returns vary according to location and electricity pricing.

This is much stronger evidence than simply accepting a political party's estimated savings. Understanding the value of residential solar in NZ

4. Which proposals are most relevant to renters with changing incomes?

This is where I would look beyond headline promises about cheaper electricity.

You and your partner have two particular vulnerabilities:

• You cannot necessarily make permanent improvements to a rental property.
• You cannot reliably predict how much money will come in each week.

Here is how the policies compare against those circumstances.

What matters to you	Most relevant proposal
Lower bills without owning a home	Labour's plug-in solar and subsidies
Access to solar as a renter	Labour and Greens
Lower electricity prices over time	National, ACT and Greens
More competition between power companies	National, ACT and NZ First
Stronger intervention against excessive prices	Labour and Greens' greater regulatory/public role
Community access to cheaper electricity	Labour and Greens
Reducing infrastructure costs	ACT and National

There are two things I would be particularly careful about.

First, don't confuse a lower electricity bill with a lower cost of living.

If you receive a $20 reduction in your monthly electricity bill but have to pay $50 towards a solar system, you are worse off in the short term.

For people with irregular income, the upfront costs and repayment arrangements matter enormously.

Second, solar isn't automatically a good deal for every renter.

Labour's projected $300–$400 annual savings sound attractive, but you should consider:

• Whether your rental gets enough sunlight.
• Whether you are home during daylight hours to use the electricity.
• Whether you can take the equipment with you if you move.
• Whether the subsidy covers the upfront cost.
• Whether the landlord's permission or electrical safety requirements apply.

A plug-in system could be much more accessible than conventional rooftop solar, but the practical details matter.

5. Questions I would ask candidates before voting

Rather than asking candidates whether they support cheaper electricity (almost everyone does), I would ask them these five questions:

1. What will you do to reduce the average household power bill within your first two years in government? Can you give a realistic dollar estimate?

2. What will you do for renters? Can someone who doesn't own their home access solar subsidies or cheaper community electricity?

3. How will you protect households against electricity price increases when their income is irregular? Will there be stronger protections against unexpected bills and disconnection?

4. How will you reduce network charges? These are a significant part of electricity bills and are increasing.

5. How will you measure success? Will you publish changes in actual household bills, rather than just wholesale electricity prices or the number of new power stations?

The independent organisation Rewiring Aotearoa has also published a useful set of questions and a side-by-side comparison of the parties' energy policies.

6. My overall assessment

I wouldn't claim that one party has conclusively demonstrated that it can deliver the cheapest electricity. The proposals have not all been independently costed or tested, and several depend on infrastructure and regulatory changes that will take years.

But there are some meaningful differences.

• National: Has a credible supply-and-competition strategy. The biggest uncertainty is how quickly wholesale savings will reach households.
• Labour: Has a particularly relevant proposal for renters through plug-in solar and direct household assistance. Its estimated savings need to be tested against real household circumstances.
• Greens: Offer a more ambitious public investment and renewable energy strategy. The effectiveness depends on how Kiwipower is funded and operated.
• ACT: Has some sensible proposals for controlling network and connection costs, although the immediate benefit to existing households is uncertain.
• NZ First: Offers the most dramatic change to the existing electricity market, but the assumption that breaking up generators and retailers will lower bills needs stronger evidence.

My biggest takeaway: Don't judge these parties only on whether they promise cheaper electricity generation. Look at whether they have a credible plan to reduce the actual amount households pay, including network costs and retail charges.

For your circumstances, I would give particular weight to renter eligibility, upfront costs, protection against unexpected bills and whether savings are achievable without taking on debt.

Sources worth reading before election day

These are useful starting points for checking the promises against the evidence:

1. Electricity Authority – 2026 power price increases and their causes.
2. Commerce Commission – Why electricity network charges are increasing.
3. EECA – Independent research on residential solar.
4. Rewiring Aotearoa – 2026 party energy policy comparison.
5. MinterEllisonRuddWatts – Election 2026 energy policy comparison.

One final thought: with your rostered hours, I would also consider whether a party has a broader household affordability policy that helps when income drops unexpectedly, rather than relying entirely on electricity market reforms. Even a successful long-term electricity policy might not help much with next month's rent and bills.
