While NZ tinkers with energy, global peers surge ahead

Saturday, 6 June 2026

Finance Minister Nicola Willis has defended the Budget’s focus on energy security, including back-up generation, fuel reserves and support for businesses moving away from gas.

ANALYSIS: The Government has spent much of this year warning that New Zealand faces an energy security challenge, with rising power prices, shrinking gas supplies and a war exposing the country’s vulnerability to imported fuel.

Yet Budget 2026 contained little that looked transformative, with its main energy-security measures adding up to about $434 million.

Meanwhile, Australia has committed more than A$7 billion (NZ$8.51b) to household batteries, while China’s clean-energy sectors were worth more than US$2 trillion (NZ$3.41t) in 2025, as both countries treat clean energy as a central economic and energy security strategy.

The Government is focused on managing shortages, dry-year risk and supply disruption, rather than rapidly changing the way households and businesses generate, store and use power.

The Budget’s main direct energy security measures included $200m for Genesis Energy, $150m for extra fuel supply arrangements, $30m for solar in schools, and $48m set aside for potential losses under the gas transition loan guarantee scheme, plus $5.9m for Energy Efficiency and Conservation Authority to support the scheme.

Australia, by contrast, has expanded its cheaper home batteries programme, aiming to help more than two million households install batteries and add about 40GWh of storage capacity by 2030.

As a result, regulators expect power bills to fall by up to 10.7% for some households and up to 20.9% for some small businesses across parts of the eastern states.

It’s a similar pattern with electric vehicles. While Australia and China have used subsidies and incentives to accelerate the shift away from fossil fuels, Budget 2026 contains little aimed at directly encouraging EV adoption, continuing the Government's preference for market-led uptake over large-scale consumer subsidies.

At a speech in Christchurch on Wednesday, Finance Minister Nicola Willis framed New Zealand's energy challenge as what happens when “the sun’s not shining, the wind’s not blowing and the lakes are running low”.

Willis argues New Zealand’s energy security challenge is not how to generate more electricity on sunny or windy days, but how to keep the lights on when renewable generation is low and hydro lake levels are under pressure.

Renewable energy advocates argue that misses part of the equation: more solar and wind generation can reduce day-to-day hydro use, leaving more water in the lakes for the very periods of shortage Willis is worried about.

Renewable energy advocates argue more solar and wind could preserve water in hydro lakes for dry years and during peak demand.

University of Auckland Professor Emeritus Ralph Cooney makes that argument, saying an increase in solar generation could help retain more water in the country’s hydro lakes during dry years.

Energy analysts argue the cost of fossil fuel dependence is no longer just environmental, but economic, especially as oil price shocks have become a recurring feature of the global economy.

Countries have already responded to the current US attack on Iran by rethinking fossil fuel exposure, with China cancelling a planned liquefied natural gas (LNG) import terminal expansion and Vietnam cancelling 4.8GW of LNG-fuelled power generation.

That sits awkwardly with National’s plan to support an LNG import facility in Taranaki, which the Government says would improve energy security, but critics argue could deepen the country’s exposure to volatile international gas markets.

If New Zealand gets the balance wrong, households and businesses could spend years paying for back-up supply, network upgrades and fuel resilience, while the country moves too slowly on the technologies that reduce pressure on the grid in the first place.
