Every question, every answer, every source

As of 5 October 2026, the election is on 7 November 2026, and energy has become a major dividing line. New Zealand Parliament dissolved ahead of tight November vote

The simplest way to understand the parties is:

• National/ACT: increase supply, rely mainly on competition and private investment, and retain gas/LNG as insurance.
• Labour/Greens/Te Pāti Māori: accelerate renewable electricity and electrification, reducing exposure to imported fossil-fuel prices.
• NZ First: intervene much more heavily in the electricity market and pursue domestic oil/gas resources for energy sovereignty.

At a glance

Party	Electricity prices	Petrol/diesel costs	Security of supply
National	More generation, competition, solar and batteries; reform lines charges	No fuel-tax rise in 2027; 5c/L rise starts 2028; strategic fuel reserves	Renewables + gas/LNG + fuel reserves
ACT	More private investment and competition; let consumers sell their own power	Mainly market-led; less reliance on petrol through electrification	LNG in near term, plus batteries, renewables and more generation
Labour	Renewable build-out, solar/batteries, public investment; tougher action on excessive pricing	Freeze fuel tax for 3 years	Renewable energy, storage and grid investment; no LNG terminal
Greens	Publicly backed renewable generation, solar, batteries and Kiwipower	Reduce dependence on petrol through EVs/public transport	Renewable firming/storage; oppose LNG
NZ First	Break up the big gentailers and change the wholesale market	Develop domestic oil/gas and investigate greater fuel sovereignty	Domestic oil/gas + reserves + electricity reform; Marsden Point emphasis
Te Pāti Māori	Community-owned renewable energy, solar, batteries and microgrids	Reduce dependence on imported fossil fuels	“Energy sovereignty”: local renewable generation/storage rather than LNG

National

National's central argument is that high electricity prices are fundamentally a supply problem. Its 2026 Electrify NZ 2.0 plan would make it easier to build wind, solar, hydro and batteries, allow private investment in transmission, make household solar exports more competitive, tackle lines charges and establish a Home Energy Fund offering low-interest loans for electrification. It also wants new AI data centres to bring additional firmed electricity supply. Affordable power Kiwis can rely on | National Party

For reliability, National is particularly concerned about dry years, when hydro generation is constrained. It proposes standardised backup-power contracts and auctions to encourage investment in backup generation. Affordable power Kiwis can rely on | National Party

On transport fuel, the position has actually changed during 2026: National cancelled the planned 12c/L fuel-excise increase for 2027. Instead, a 5c/L increase begins in January 2028, followed by further 5c increases. Government cancels fuel tax hike | National Party

For fuel security, the Government has added diesel storage at Marsden Point and secured an additional 90 million litres of diesel, equivalent to about nine days of supply. Flexibility, adaptability key to Fuel Response Plan | National Party

Bottom line: National expects prices to fall as more generation comes online, while keeping gas/LNG available as insurance against electricity shortages and maintaining imported-fuel contingency measures.

ACT

ACT is even more explicitly market-led.

It argues that the answer to expensive electricity is more generation, investment and competition rather than breaking up the gentailers or imposing price controls. Its September policy would:

• allow households to sell surplus solar power to whichever retailer offers the best price;
• open transmission to private investment;
• strengthen competition rules;
• make monopoly lines companies demonstrate value for money;
• encourage more generation and investment. ACT New Zealand

ACT also sees gas as necessary insurance while New Zealand builds enough renewable generation and storage. It has argued that an LNG terminal is the best short-term replacement for declining domestic gas, particularly for dry-year electricity security. ACT New Zealand

It wants faster development of batteries and simpler rules for installing household solar. ACT New Zealand

Bottom line: ACT's prescription is essentially “build much more electricity and let competition sort out prices”, with LNG/gas providing insurance when renewable generation isn't sufficient.

Labour

Labour's approach is much more interventionist on the energy transition.

It says New Zealand should rapidly build home-grown renewable electricity—hydro, wind, solar and geothermal—and use electrification to reduce exposure to global oil and gas shocks. Labour says it would put money through its Future Fund into new generation, storage and grid upgrades. Speech: Electrify Queenstown

For households, Labour's SolarSaver programme would provide government-backed long-term low-interest finance for solar and batteries, plus $3,000 subsidies for low- and middle-income households. It also proposes a $30m community-battery fund. Election 2026: Political polarisation on energy and climate, except solar | PHCC

Labour has also made a significant fuel-price commitment: it will freeze fuel excise for three years. Release: No increase in fuel taxes under Labour

It proposes making price gouging illegal, covering essential goods and services including energy and fuel, with the Commerce Commission able to investigate companies with significant market power. Labour's 2026 Election Policies

On supply security, Labour says it would reinstate the ban on new oil and gas exploration and not proceed with the LNG import terminal. Its argument is that relying on imported LNG simply replaces one form of international fossil-fuel exposure with another. Speech: Electrify Queenstown

Bottom line: Labour's strategy is electrify the economy and build enough renewable generation/storage that global fossil-fuel shocks matter less.

Greens

The Greens go furthest in shifting electricity away from the existing market model.

Their 2026 energy plan proposes Kiwipower, a publicly owned generation company intended particularly to solve the dry-year/firming problem where the market has struggled to provide sufficient reliable renewable capacity. News - Services and Systems - Green Party of Aotearoa New Zealand

They also propose:

• interest-free loans for household solar;
• solar on public and Māori housing;
• $200m for community-owned renewable energy;
• expanded home-energy efficiency programmes;
• batteries and distributed generation. NZ Political Party Energy Policies — 2026 | Electrification NZ

The Greens' broader strategy is to get households and transport off fossil fuels. That includes more EV charging, incentives for EV uptake, public transport investment and eventually a phase-out date for importing fossil-fuel-powered vehicles. Election 2026: Political polarisation on energy and climate, except solar | PHCC

They strongly oppose the planned LNG import facility, arguing that it would expose consumers to volatile international gas prices rather than delivering genuine energy independence. Methanex closing eliminates any arguable case for LNG Terminal - Green Party of Aotearoa New Zealand

Bottom line: the Greens' answer is renewables + storage + public ownership + electrification, rather than more fossil-fuel infrastructure.

New Zealand First

NZ First has arguably the most radical electricity-market reform.

It proposes breaking up the large vertically integrated electricity companies—the “gentailers”—so that generation and retail are separated. It says this would prevent the large companies from controlling both the production and retailing of electricity and increase competition. "Power to the People" - Winston Peters - State of the Nation 2026 - New Zealand First

It also proposes:

• guaranteed long-term fixed-price contracts for new generation;
• giving new generation priority access to customers;
• allowing households with solar to sell power back at the same price they pay;
• a National Energy Strategy. "Power to the People" - Winston Peters - State of the Nation 2026 - New Zealand First

On fuel security, NZ First is much more willing than Labour or the Greens to pursue domestic oil and gas. Its latest proposal commits $1 billion over the next term to survey New Zealand's offshore/subsurface energy resources, with the aim of developing domestic oil and gas resources if commercially viable. Future Proofing our Fuel Security - New Zealand First

The party says domestic resources could eventually lower fuel and electricity costs and reduce reliance on overseas supply chains. It also favours strategic fuel reserves and a special economic zone around Marsden Point. Budget 2026: Common sense wins for NZ First - New Zealand First

Bottom line: NZ First combines strong government intervention in electricity markets with much greater use of domestic fossil-fuel resources for energy sovereignty.

Te Pāti Māori

Te Pāti Māori's central concept is “energy sovereignty”.

Its proposed direction is to invest in rooftop solar, batteries, community microgrids and community-owned renewable generation, particularly for rural communities, marae and Māori housing. It argues that producing energy locally keeps money in New Zealand and makes households less exposed to international oil and gas shocks. We Must Act Now On Energy Sovereignty- Every Household Is Paying The Price | Scoop News

It has specifically opposed dependence on an LNG solution and favours storage and flexible electricity demand as part of security of supply. NZ Political Party Energy Policies — 2026 | Electrification NZ

The party has been less specific than the Greens or National about the exact dollar amounts and mechanisms it would use, with some detailed energy policies still to be announced. Election 2026: Political polarisation on energy and climate, except solar | PHCC

Bottom line: Te Pāti Māori's model is locally owned renewable energy + batteries + community generation, aimed at both lowering bills and reducing dependence on imported fuel.

The real choice for voters

There are really three competing theories behind these policies:

1. National/ACT — “Build more, let markets work.”
More wind, solar, hydro and batteries, fewer regulatory barriers, private investment, and gas/LNG to cover the gaps. They expect increased supply to bring electricity prices down.

2. Labour/Greens/TPM — “Electrify out of the problem.”
Invest heavily in renewable generation, solar, batteries, grids, EVs and public transport. The idea is that electricity is a domestic resource whereas oil and gas prices are set by volatile international markets.

3. NZ First — “Take control of the energy system.”
Break up the gentailers, intervene more directly in electricity pricing and generation, and simultaneously develop New Zealand's own oil and gas resources to reduce dependence on imports.

One important distinction: none of the parties can guarantee a particular petrol or electricity price. International oil prices, rainfall/hydro conditions, interest rates, construction costs and the cost of capital will still matter. The policies mainly differ over how much government should intervene and whether New Zealand's long-term answer is more fossil-fuel supply, more renewable supply, or a combination.

If your priority is specifically “Which party is most likely to reduce an average household's total energy bill over the next 3–5 years?”, I can compare the parties on that question separately, including estimated effects on an Auckland household's electricity bill and petrol costs.
