New Zealand election 2026: Which electricity policies could bring down your power bill?

The key distinction is between policies that might lower electricity prices for everyone and policies that help individual households pay less. Those are different goals, and parties are proposing different ways to achieve them.

Because you rent with your partner and your income changes from week to week, three things are especially relevant to your decision:

• Lower ongoing bills: Will a policy reduce the amount you pay for electricity, rather than just provide temporary assistance?
• Help for renters: Can you benefit if you don't own your home or have the money to install solar panels?
• Reliable savings: Is there credible evidence that a proposal will reduce prices, and how long might that take?

New Zealand's 2026 general election is scheduled for 7 November 2026. As of late October, the parties have announced several energy policies, but their proposals vary in detail, and independent assessments of their likely effects on household bills are limited. minterellison.co.nz, undecided.nz

The comparison below separates what parties are promising from what the available evidence can actually establish.

1. Why electricity bills are rising

The first thing to understand is that electricity bills aren't determined by a single cost.

Component	What it pays for	Why it matters
Generation and wholesale electricity	Producing electricity and buying it on the wholesale market	More supply and effective competition can put downward pressure on prices.
Transmission and distribution	The national grid and local power lines	Network upgrades and maintenance can increase bills even when wholesale electricity prices fall.
Retailing and margins	Customer service, billing, risk management and the retailer's commercial return	Competition and better regulation may reduce some costs or improve the deals available.
Fixed daily charges and other costs	Connection charges, metering and applicable levies	These can remain payable even when you use less electricity.

The Electricity Authority reported in August 2026 that average electricity prices for households and small businesses rose by 6.8% in the first half of 2026, following an 8% increase in 2025.

Its analysis attributed 54% of the average increase in 2026 to higher network charges. Energy costs were another significant factor, particularly for independent retailers. The Authority cautioned that the underlying energy costs and margins of the large generator-retailers are difficult to separate precisely. ea.govt.nz

This matters when evaluating campaign promises. A policy that lowers wholesale electricity prices might not immediately reduce your total bill if the cost of maintaining the power network continues to rise.

There is also a timing problem: retailers don't necessarily pass on wholesale price reductions immediately. The Authority reported that wholesale prices had been falling, but some households were still experiencing retail price increases. ea.govt.nz

The practical test: Does a policy address the part of the bill that is increasing, and is there a credible mechanism for those savings to reach households?

2. What the parties are proposing

The following comparison covers the seven parties included in current 2026 election energy-policy comparisons: National, Labour, the Greens, ACT, New Zealand First, Te Pāti Māori and Opportunity.

National: Increase supply and encourage competition

National's approach is to make it easier to build electricity generation and infrastructure, encourage private investment, and improve competition between electricity retailers.

Its announced measures include:

• Electrify NZ 2.0: Make it easier to build new generation and transmission infrastructure, including renewable energy projects.
• More competition: Improve access to electricity market products and make it easier for independent retailers to compete with the large generator-retailers.
• Affordability as a regulatory objective: Give the Electricity Authority an explicit focus on affordability alongside competition, efficiency and reliability.
• Home Energy Fund: Offer long-term financing for household investments such as solar panels, batteries and insulation.
• Security of supply: Support domestic gas development and an LNG import facility to provide backup electricity supply when renewable generation and hydro storage are constrained.

National's broader argument is that increasing supply, reducing barriers to investment and improving competition can bring prices down. mail.powercompare.co.nz, minterellison.co.nz

What is the evidence?

There is a credible economic mechanism behind building more generation: additional low-cost electricity can reduce wholesale prices, particularly when supply is tight. But new power stations and grid connections take time to develop, and their construction costs must ultimately be recovered.

The OECD has highlighted the importance of new investment in generation and backup capacity to improve New Zealand's electricity affordability and reliability. It has also warned that investment uncertainty and gas shortages have contributed to wholesale price pressure. oecd.org

The LNG proposal is more contested. Imported gas could provide backup during dry years, but the facility and fuel would also carry costs. The OECD has argued that LNG should be treated as a transitional measure, while New Zealand develops alternatives to gas-dependent backup generation. oecd.org

What this could mean for you: National's proposed Home Energy Fund is potentially relevant if you're renting, but a loan for property improvements is not the same as a reduction in your electricity tariff. You would need to check the final eligibility rules, especially whether renters could participate directly.

Labour: Help households generate their own electricity and strengthen consumer protection

Labour's main proposals focus on household solar power, community energy and regulation of electricity pricing.

Its announced measures include:

• SolarSaver: A proposed $160 million programme to help households install solar panels, with long-term finance and subsidies of up to $3,000 for eligible households.
• Support for renters: Enable plug-in solar panels, allowing some renters to generate electricity without installing a conventional rooftop system.
• Community batteries: Support shared energy storage.
• Solar buy-back rates: Improve the terms households receive when they sell surplus electricity to the grid.
• Action on excessive pricing: Make price gouging illegal and strengthen the Commerce Commission's powers to investigate businesses with significant market power.
• Oil and gas exploration: Restore the ban on new oil and gas exploration.

These measures are intended to reduce household electricity purchases, improve returns for people who generate surplus power, and strengthen consumer protections. mail.powercompare.co.nz, minterellison.co.nz

What is the evidence?

Solar panels can reduce the amount of electricity a household buys from its retailer. However, the savings depend on installation costs, sunlight, electricity usage patterns, the tariff paid for imported electricity and the rate received for surplus power.

For renters, plug-in solar could reduce some of the barriers associated with rooftop installations. But the amount of electricity it generates will depend on the available space, sunlight and the system's size.

The evidence for the general principle of self-generation is stronger than the evidence for the precise savings from Labour's proposed scheme. The policy's overall effect on household bills would depend on its final design, take-up and the cost of financing it.

Price-gouging legislation raises a different question: whether regulators could identify excessive pricing, establish enforceable standards and intervene in ways that lower prices without creating unintended effects on investment.

What this could mean for you: Labour's proposed renter-accessible solar and consumer protections are directly relevant to someone who doesn't own their home. However, the solar option would probably make a smaller contribution than a full rooftop system, and the price-gouging proposal does not itself guarantee a particular reduction in your bill.

The Greens: Create a publicly owned electricity company

The Green Party proposes a larger role for the Government in electricity generation and the structure of the market.

Its main measures include:

• Kiwipower: A proposed publicly owned energy company that would invest in renewable generation and backup capacity.
• Clean-energy financing: Zero-interest loans covering up to 90% of eligible household clean-energy investment costs.
• Community-owned renewable generation: Support for local energy projects.
• Solar for public housing: Expand solar generation on public housing.
• A right to solar for renters: Improve renters' ability to access solar power.
• Solar buy-back reform: Seek fairer payments for electricity exported to the grid.

The Greens argue that public investment and changes to the electricity market would help deliver more affordable and secure power. mail.powercompare.co.nz, minterellison.co.nz

What is the evidence?

Public investment can help finance infrastructure that private companies might be reluctant to build, particularly where the returns are uncertain or take many years to arrive.

There is also a strong rationale for investing in backup generation and storage. New Zealand's electricity system relies heavily on renewable generation, but its ability to produce low-cost electricity can be affected by dry weather and periods when wind generation is low.

The critical question is whether Kiwipower would add genuinely new capacity, lower the cost of backup supply and improve competition sufficiently to reduce prices. Its performance would depend on investment decisions, financing costs, governance and how it interacted with existing generators.

The Greens commissioned Infometrics to review the costings of their wider energy package. However, reporting on that review indicated that it did not model the effects of each individual proposal on the electricity market. That means it should not be treated as proof of a specific reduction in household power bills. undecided.nz

What this could mean for you: The proposed renter-accessible solar measures could help reduce electricity purchases, while the zero-interest finance proposal could reduce upfront barriers for eligible investments. Kiwipower is a longer-term structural proposal, so its effects on your household bill are less certain in the near term.

ACT: Encourage private investment and reduce barriers to building power infrastructure

ACT's policy emphasises private-sector investment, regulatory certainty and increasing electricity supply.

Its approach includes:

• Keeping the large generator-retailers together rather than forcing them to split into separate businesses.
• Making it easier for private investors to build new electricity infrastructure.
• Reviewing the costs and requirements imposed on electricity lines companies.
• Supporting greater development of domestic energy resources.

ACT argues that forced restructuring could discourage investment in new generation. Its position is that the electricity market needs more supply and a stable environment for businesses to invest. MinterEllisonRuddWatts' 2026 policy comparison

What is the evidence?

Reducing unnecessary regulatory barriers can make worthwhile projects faster or cheaper to build. But the effect depends on whether those barriers are actually preventing investment and whether savings are passed through to consumers.

Keeping the large companies intact avoids the immediate disruption and potential costs of restructuring them. However, it also means relying on competition rules and new investment to address concerns about market power.

The OECD's 2026 assessment supports improving market rules and competition before pursuing a potentially disruptive structural separation of generators and retailers. It does not establish that ACT's entire policy package would lower household bills by a particular amount. oecd.org, oecd.org

What this could mean for you: ACT's proposals primarily aim to change how electricity is supplied and regulated. They do not, by themselves, promise a specific reduction in your household's bill.

New Zealand First: Split the major electricity companies and change how power is priced

New Zealand First proposes more substantial changes to the structure of the electricity market.

Its measures include:

• Separating generation from retailing: Split the four major generator-retailers into distinct businesses.
• Changing wholesale pricing: Replace the existing system in which the highest-priced offer needed to meet demand sets the wholesale price for all accepted generation.
• Long-term contracts: Guarantee long-term, fixed-price contracts for new power stations.
• Marsden Point: Establish a special economic zone at the former oil refinery site.

The party argues that restructuring the market would reduce opportunities for generators to restrict supply or benefit from the current pricing arrangements. Its proposals are described in its electricity market policy and in independent election-policy comparisons. undecided.nz, undecided.nz

What is the evidence?

Separating electricity generation from retailing is a significant structural change, but its effect on household prices is uncertain.

The potential benefit is that independent retailers might be able to compete more effectively if they can access wholesale electricity on fairer terms. More competition could improve retail offers and reduce some costs.

The risks are that restructuring could be expensive, create uncertainty for investors and fail to address other major cost pressures, particularly network charges and the need for new generation.

The OECD's 2026 analysis favours improving market rules, strengthening competition and increasing investment in backup capacity before resorting to structural separation if those measures prove insufficient. It does not provide a forecast of household savings from New Zealand First's proposal. oecd.org, anthill.co.nz

Changing the wholesale pricing mechanism is a separate proposal. Its success would depend on how the replacement system sets prices, rewards new generation and ensures enough electricity is available during shortages.

What this could mean for you: The intended benefit is a change in the underlying price of electricity, rather than just assistance with installing solar. But there is no established, independently verified estimate of how much your household bill would fall under New Zealand First's proposed system.

Te Pāti Māori: Greater energy sovereignty and community control

Te Pāti Māori's approach emphasises energy sovereignty, community participation and reducing reliance on existing electricity market structures.

Its announced direction includes:

• Greater community involvement in energy generation and supply.
• Investment in renewable energy and local energy systems.
• More accessible household energy improvements.
• Alternatives to relying on imported gas to manage electricity shortages.

Its energy platform is set out in its Energy Sovereignty policy, which is linked from the current election-policy comparison. minterellison.co.nz, undecided.nz

What is the evidence?

Community generation and local energy systems can give households and communities more control over their electricity supply. Storage and flexible electricity use can also help reduce pressure on the wider grid.

However, the effect on the average household bill depends on the scale of investment, the cost of the technology, how the systems are financed and whether they can provide electricity when it is most needed.

The main limitation is that the available independent analysis does not establish a specific reduction in household bills attributable to Te Pāti Māori's proposals. undecided.nz

What this could mean for you: The approach is relevant if you are interested in community-based energy and alternatives to the existing market. To assess the immediate financial benefit, you would need more detail about eligibility, funding and the expected savings for renters.

Opportunity: Back new generation and reform the electricity network

Opportunity's energy policy focuses on increasing investment in electricity generation and changing how the network is regulated.

Its proposals include:

• Revenue support for new generation: Use a capacity investment scheme to support renewable generation and storage.
• Electricity network reform: Group the 29 local lines companies into six to eight larger groups while retaining local ownership.
• Changes to network regulation: Adjust the rules governing lines companies and Transpower to encourage investment ahead of anticipated demand.
• Market structure: Retain the existing generator-retailer model rather than forcing the major companies to split.

The party's stated approach is to address insufficient investment and the incentives that influence when new electricity infrastructure is built. Its proposals are detailed in its Abundant Energy policy, linked from the election-policy comparison. minterellison.co.nz, undecided.nz

What is the evidence?

Revenue guarantees can make it easier to finance power stations whose earnings would otherwise be too uncertain. More generation and storage could help reduce price spikes and improve supply reliability.

However, these guarantees also allocate financial risk to the scheme's funders, potentially including taxpayers or electricity consumers. The final impact depends on the contracts, the projects supported and the costs of the scheme.

Consolidating lines companies might reduce some administrative duplication or improve investment planning. But any savings would need to outweigh transition costs and translate into lower network charges.

What this could mean for you: Opportunity's proposals aim to address the underlying cost and reliability of electricity supply. However, there is no independent estimate establishing how much its complete package would save a typical renting household.

3. Which proposals have the strongest evidence behind them?

It helps to distinguish evidence that a policy can work in principle from evidence that a particular party's proposal will reduce your bill by a specific amount.

Those are not the same thing.

The following table summarises the main approaches without ranking the parties.

Policy approach	What the evidence supports	What remains uncertain
Build more electricity generation	Additional low-cost supply can reduce wholesale price pressure.	Construction costs, timing, financing and how quickly savings reach consumers.
Improve competition between retailers	Effective competition can improve retail offers and put pressure on margins.	How much competition will improve and how much consumers will save.
Separate generation and retail businesses	Separation could reduce some conflicts of interest and improve independent retailers' access to power.	Whether the benefits would outweigh restructuring costs and whether household prices would fall.
Invest in backup generation and storage	Firm supply and storage can help manage dry years and shortages.	The cheapest combination of technologies and how its costs would be recovered.
Help households install solar	Self-generation can reduce the amount of electricity bought from retailers.	Installation costs, eligibility, actual household usage and savings after financing costs.
Regulate excessive pricing	Stronger enforcement can address proven anticompetitive conduct or unlawful pricing.	How excessive pricing would be defined and the effect on prices, investment and competition.
Reform electricity network charges	Better planning and efficient investment can help manage infrastructure costs.	Whether the reforms would reduce charges rather than simply slow necessary upgrades.

The OECD's 2026 economic assessment is useful because it considers the wider electricity system rather than evaluating campaign claims alone. It identifies gas shortages, dry-year price spikes and uncertainty about investment in backup generation as significant problems. It recommends stronger competition, improved market rules and more investment in non-gas backup capacity. oecd.org, oecd.org

A particularly important distinction: changing the market versus changing the rules

The large New Zealand generator-retailers are often called gentailers because they both generate and sell electricity.

New Zealand's four main gentailers are Contact Energy, Genesis Energy, Mercury and Meridian Energy. The Crown owns 51% of Genesis, Mercury and Meridian.

There are two broad approaches to the market structure:

• Keep the companies together but improve the rules. This is broadly the approach taken by National and ACT.
• Separate generation and retailing. New Zealand First proposes this, while the Greens have also supported separation as a possible structural response if other measures do not work.

Labour's policy includes stronger consumer protection and solar support, but it has not committed to the same structural separation proposal as New Zealand First. Opportunity opposes a forced split. undecided.nz

The OECD's assessment is significant here: it recommends improving market design and conduct rules first, with structural separation reconsidered if those measures fail to deliver sufficient investment, competition and affordability.

That does not prove that separation would never work. It means the evidence does not establish that a forced split is necessary or that it would produce a particular reduction in your power bill. oecd.org

4. What could help you as a renter with fluctuating income?

For your situation, I would separate the policies into three categories: immediate ways to reduce costs, measures that could help over the next few years, and long-term market reforms.

A. Reducing what you pay now

One of the most practical things to investigate is whether you are on an electricity plan that suits your household's usage.

The Electricity Authority operates Billy, an electricity comparison service. Its August 2026 report said people who initiated a switch through Billy saved an average of about $82 for that month. That is a reported average, not a guarantee of savings for every household. ea.govt.nz

You can use the Authority's comparison service here:

• Billy electricity comparison service

When comparing plans, look beyond the advertised discount:

• Compare daily fixed charges as well as per-kWh rates.
• Check whether discounts depend on paying on time or meeting other conditions.
• Check whether the plan has cheaper off-peak rates that suit when you actually use electricity.
• Consider whether you can manage the payment arrangements during weeks when your combined income is lower.

For someone whose pay varies, a plan with a slightly lower headline rate but a high fixed daily charge may not necessarily be the cheapest option.

B. Reducing bills over the medium term

Solar power is potentially relevant to renters, but the details matter.

Labour and the Greens have proposed measures to improve renters' access to solar, while National has proposed household energy financing.

Before treating any of these as a likely saving, check:

• Whether renters qualify directly.
• Whether the property owner must consent.
• Whether the installation can be taken with you when you move.
• Whether you need to borrow money or pay installation costs.
• How much electricity the system is expected to generate.
• Whether the savings are calculated after all financing and connection costs.

An important point: a scheme that reduces upfront costs can make an investment accessible without necessarily making it cheaper overall.

Because you rent, you would also want to know whether any savings would benefit you directly or whether the main financial benefit would accrue to the property owner.

C. Protecting yourself against future price increases

This is where market reforms and investment in generation matter.

More affordable electricity supply could benefit households regardless of whether they own their homes. But these policies usually take longer to implement, and the effects on retail prices are not guaranteed.

Network charges are particularly important. The Electricity Authority has reported that higher lines charges are expected to continue affecting bills through to 2030, although the pace of increases is expected to slow. Falling wholesale prices may help offset some of that pressure. ea.govt.nz

For you, a useful question is therefore whether a party has explained how its policies will address both the price of electricity itself and the cost of delivering it to your home.

---

5. How much confidence should you place in the parties' claims?

As of 19 October 2026, an independent election-policy comparison reported that it had found no independent costing of any party's complete electricity policy package.

It also found that the most extensive published analysis concerned structural separation of the generator-retailers, but that this research did not establish the savings attributable to any particular party's proposal.

The Greens commissioned an assessment of their package's costings, but that did not independently demonstrate the market effects of each individual policy. For National, Labour, ACT, New Zealand First, Opportunity and Te Pāti Māori, the comparison found no independent analysis quantifying the effects of their complete packages on household bills. undecided.nz

This does not mean the policies are ineffective. It means you should distinguish between three different types of evidence:

1. An established mechanism: For example, generating electricity at a lower cost can put downward pressure on wholesale prices.
2. A plausible policy proposal: For example, a new investment scheme could encourage companies to build more generation.
3. A demonstrated household saving: For example, independently modelled evidence showing how much a particular policy would reduce a household's annual bill, after accounting for its costs.

The first type of evidence is available for several proposals. The second describes much of the election debate. The third is generally missing from the parties' complete electricity policy packages.

That is an important limitation when comparing campaign promises.

6. Questions worth asking before you vote

Given that you rent and your combined household income can change from week to week, these questions may help you assess the proposals on their practical merits.

Question	Why it matters
Will this policy reduce electricity prices, or simply help some households pay their bills?	Distinguishes market-wide changes from targeted assistance.
Can renters benefit without taking on debt?	Tests whether the policy is accessible to households without property assets.
How long will it take to affect retail prices?	Separates potential immediate relief from long-term investment.
Does the policy address network charges as well as generation costs?	Tests whether it addresses a major driver of recent price increases.
Is there an independent estimate of the savings?	Helps distinguish a campaign promise from a quantified outcome.
Who pays if the policy costs more than expected?	Identifies potential costs to taxpayers, electricity consumers or investors.
What happens during dry years or electricity shortages?	Tests whether a proposal addresses price spikes as well as average prices.

For your household, I would pay particular attention to the answers about renter eligibility, upfront costs, fixed charges and the time it takes for savings to reach electricity bills.

Those details may matter more to your day-to-day finances than a party's headline promise to make electricity cheaper.

7. Where to check the policies before election day

These sources can help you verify the proposals and compare the evidence.

• Official party policy comparison: MinterEllisonRuddWatts' 2026 election energy-policy snapshot — compares the published positions of the seven parties.
• Independent policy breakdown: Undecided — electricity prices and supply — examines differences between the parties and discusses the available evidence and limitations.
• Official electricity price data: Ministry of Business, Innovation and Employment electricity price monitoring — publishes national household electricity cost and tariff data.
• Electricity market monitoring: Electricity Authority — publishes information about electricity pricing, competition and consumer protections.

Bottom line

New Zealand's parties are proposing different routes towards more affordable electricity: more private investment, stronger competition rules, household solar, public investment in generation, changes to the structure of electricity companies, and reforms to network regulation.

There is credible evidence that several of the underlying mechanisms can work. However, there is not enough independent evidence to say that any party's complete 2026 electricity policy package will deliver a particular reduction in your household bill.

For a renting household with variable income, it is worth distinguishing between policies that might eventually lower electricity prices for everyone and those that provide a practical, affordable way to reduce your own electricity costs.

The most useful next step is to examine the final policy details and ask each party to substantiate its expected household savings, including how long they would take to materialise and whether renters would qualify.

That gives you a way to assess the competing promises without having to rely on campaign slogans alone.
