NEW ZEALAND is renowned for its pristine landscapes, from snow‑capped mountains and fjords to lush rainforests and golden beaches. With a population of around 5.1 million, it combines a small, dispersed populace with vast natural beauty, making conservation and sustainable energy transitions both vital and highly visible to its citizens.
With the closure of the Strait of Hormuz due to escalating conflict in Iran sending shockwaves through global energy markets, oil prices are above US $100 a barrel and spilling into record‑high petrol prices in New Zealand — topping NZ$3 a litre – and leaving some stations without fuel. This isn’t a distant price blip; for a country that imports 100 % of its petrol, diesel and jet fuel, it’s a stark wake‑up call about strategic vulnerability.
New Zealand’s domestic refining capacity ended in 2022 when Marsden Point stopped refining crude, leaving the country wholly reliant on imports mostly processed in South Korea and Singapore. Those refineries depend on crude shipments that run through the waters now disrupted by Middle East tensions. Official fuel stock figures show just about 52 days’ total fuel cover and around 33 days of petrol, a buffer designed for routine hiccups — not protracted geopolitical disruption.
This fraught reliance on imported petroleum underscores a deeper structural failure: while New Zealand has one of the cleanest electricity grids on Earth, its transport sector remains stubbornly oil‑dependent.

Electric Vehicles: Growth, Headwinds, and Reality
There’s been real momentum in electric vehicle (EV) adoption — but the headline figures need context.
Registrations of new battery electric (BEV) and plug‑in hybrid (PHEV) vehicles in New Zealand recently passed 100,000 across the fleet, a symbolic milestone for electrification. (AfMA)
According to government and industry data, the plug‑in electric fleet stood at about 135,000 vehicles by the end of 2025, encompassing ~92,500 BEVs and ~42,800 PHEVs — roughly 2.8 % of the national fleet of ~4.9 million vehicles. (Wikipedia)
That’s progress, but it’s also a reminder that fossil fuel cars still dominate, and the fleet turnover rate means decades could pass before oil‑free transport is the norm without policy support and infrastructure expansion. EV uptake — especially in new vehicle sales — has fluctuated, partly because of changes to government incentives and lingering range anxiety and charging infrastructure gaps. (Ministry for the Environment)
In fact, recent reporting suggests the EV share of new registrations has crept up but remains uneven — for example, around 6–7 % in certain months. While this is growth, it’s not yet the disruptive shift infrastructure and climate targets require. So while Kiwi households are increasingly choosing electric over petrol on a personal level, policy support and charging network build‑out remain key levers that are under‑deployed relative to the scale of the transition needed.
The country’s EV charging infrastructure has grown steadily over the last decade. More than 1,200 public and private chargers now operate nationwide, supported by the Energy Efficiency and Conservation Authority’s Low Emission Transport Fund. The government aims to expand this to a nationwide network of 10,000 chargers by 2030 to overcome range anxiety and support wider EV adoption. (EECA)
According to projections tied to the Climate Change Commission’s modelling, up to 550,000 light passenger and light commercial EVs could be on New Zealand roads by 2030. That assumes continued policy support and charging infrastructure build‑out. By then, it’s expected that EVs could make up around 62% of new light vehicle registrations. By 2035, the modelling suggests 100% of newly entering cars — new and new second‑hand imports — will be electric, which would see the total EV share of the fleet reach about 38% of all light vehicles. (EECA)
In energy demand terms, this transition means EV kilometres travelled could grow from just over 2% in 2024 to nearly half (47%) by 2035 — a shift that dramatically reduces oil consumption. (EECA)
Charging infrastructure remains vital:
Public charging coverage will need to expand — especially rapid and ultra‑rapid corridors on major highways — to ensure EVs can genuinely replace petrol cars for long‑distance travel. (EECA)
Beyond Batteries: Hydrogen and Biofuels Enter the Fray
Electric cars are only part of the answer. Heavy transport, freight, buses, and sectors where batteries are currently less efficient require alternative pathways.
Hydrogen is emerging as one of the more promising options for heavy transport. Hiringa Energy- A Māori word meaning perseverance, energy, determination, inspiration, vitality – has spearheaded Australasia’s first hydrogen refuelling network, with multiple commercial stations now operational in Auckland, Hamilton and Palmerston North, and others under planning across both islands.

This infrastructure enables fuel‑cell trucks and other zero‑emission heavy vehicles to operate without diesel. Early adopters like TR Group have deployed hydrogen fuel cell electric vehicles (FCEVs) in commercial operations, cutting tens of thousands of litres of diesel from their fleets. (TR Group NZ)
Green hydrogen production — such as that from partnerships between Halcyon Power and Māori land trusts using geothermal energy — is adding supply capacity that is powered by renewable energy, not fossil fuels. (gns.cri.nz)
Biofuels are also part of the mix. New Zealand has targets to increase the share of sustainable aviation fuel and biodiesel blends, with draft mandates that would require progressively higher biofuel content in transport fuels — a practical, near‑term way to reduce oil dependence while technology transitions continue.

Where Policy Should Catch Up
The transition in New Zealand has seen enticing ideas and fragmented progress, but when petrol hits record prices, the structural weaknesses become obvious.
Despite clean electricity and global leadership potential, the policy environment has been inconsistent. Incentive programs like the Clean Car Discount boosted EV uptake, but their removal has dampened momentum. Investment in public charging infrastructure, while growing, still lags the scale required to shift mass adoption rates. (Ministry for the Environment)
Infrastructure spend still tilts heavily toward roads for fossil fuel vehicles, and rail and public transport electrification have not received comparable priority. Yet every investment in electrified buses, regional charging corridors, rail upgrades and cycleway networks is a direct bet against imported oil and future price volatility.
A Strategic Liability or Strategic Opportunity?
New Zealand’s dependence on imported petroleum is not an isolated economic quirk; it’s a strategic liability exposed by every spike in global oil prices. But the country already has the energy fundamentals to break that link into a high‑renewable electricity system, dynamic private sector innovators in electrification, hydrogen and fuels, and an emerging startup ecosystem focused on zero‑emissions transport.
This moment needn’t be a setback. If policymakers, businesses and communities treat oil dependence as a supply chain risk and national security issue, not just an environmental goal, it would unlock a broader public mission toward transport electrification and fuel diversification.
The technologies exist, capital and expertise are lining up, and New Zealand’s global energy brand — already enviable on the electricity side — could become equally formidable in transportation resilience. The next oil shock is not hypothetical. The country now has a choice: respond with urgency or pay the price again.
Renewable Energy Uptake Trends: Growth, Headwinds, and Forecasts
New Zealand’s shift to electric vehicles has been real, but it’s far from a done deal.
The next decade — particularly through 2030 — will determine whether these technologies of Electric Vehicles and Hydrogen for heavy vehicles can move from niche solutions to mainstream replacements for imported refined fuels. Policy consistency, infrastructure scale, and market signals will be the decisive factors that make this shift less vulnerable to the next global oil shock.
Hydrogen Rollout Timeline: Laying the Foundations for Heavy Transport
Battery electric technology is the best fit for most cars and light vehicles. But for heavy trucks, buses, and long‑distance freight, green hydrogen is emerging as a practical zero‑emissions alternative, and New Zealand is shaping up to be a small but pioneering market.
Initial hydrogen infrastructure is live:
In April 2024, Hiringa Energy launched what is billed as Australasia’s first zero‑emission green hydrogen refuelling network, opening stations in Wiri (South Auckland), Te Rapa (Hamilton) and Palmerston North, with a fourth under construction in Tauranga. These sites are strategically placed to service around 95% of heavy freight routes on the North Island. They are powered by renewable electricity and can refuel hydrogen fuel‑cell trucks in roughly 10–20 minutes, putting heavy hydrogen vehicles on a similar operational timeline to diesel. (NZ Trucking)
Rollout is planned to scale to 2030:
Hiringa is not stopping with the initial four stations. The company has around 24 additional stations in planning, with targets to expand the network further across both North and South Islands by 2030. These future sites aim to support increasing traffic as hydrogen fuel‑cell vehicle adoption grows among logistics and transport operators. (NZ Trucking)
Hydrogen production and ecosystem development are underway:
Another pioneer, Halcyon Power, opened New Zealand’s first commercial‑scale green hydrogen production facility tied to a geothermal power station — capable of producing around 180 tonnes of green hydrogen per year, plus a fast‑refuelling station near Auckland. (gns.cri.nz)
Initiatives are also emerging for hydrogen blending in natural gas pipelines and aviation sector hydrogen testing facilities, indicating interest in broader hydrogen economy development beyond trucks and buses. (gns.cri.nz)
Although hydrogen station infrastructure remains sparse world‑wide compared to EV charging (with hundreds in Europe and Asia), New Zealand’s emerging network marks a strategic entry point into low‑emission heavy transport. As of late 2024, the local hydrogen sector had a handful of operational stations with several planned or under development, indicating a deliberate but slow build‑out phase.
The next decade — particularly through 2030 — will determine whether these technologies can move from niche solutions to mainstream replacements for imported refined fuels. Policy consistency, infrastructure scale, and market signals will be the decisive factors that make this shift less vulnerable to the next global oil shock.
