As of May 2025, New Zealanders are facing the sharpest spike in fuel prices seen in recent years. The cost of regular unleaded petrol has surpassed NZ$3.20 per litre in many areas, while diesel prices are nearing NZ$3.00 per litre. This steep rise has caught the attention of motorists, businesses, and policymakers alike.
Key Factors Behind the June 2025 Fuel Price Surge
Several interconnected factors are pushing fuel prices higher this June. It is not a simple case of supply and demand but a confluence of global events, local policies, and market behaviors.
Impact of Global Crude Oil Prices
The global oil market has been volatile throughout early 2025. A combination of reduced outputs from OPEC+ nations and continued geopolitical tensions, particularly involving key oil-producing regions like the Middle East and Eastern Europe, has strained global supply. Crude oil prices have hovered above US$95 per barrel since March 2025, exerting upward pressure on refined fuel prices worldwide, including in New Zealand.
New Zealand Dollar Weakness
Another critical contributor is the weakening New Zealand dollar (NZD) against the US dollar (USD). Since oil is traded globally in USD, a softer NZD means Kiwis must pay more for imported fuel. By late May 2025, the exchange rate had fallen to 0.58 USD, making fuel imports significantly more expensive.
Domestic Tax Increases
In addition to international factors, the New Zealand government implemented a scheduled increase in the Fuel Excise Duty (FED) as part of its 2024 budget reforms. As of May 2025, the FED rose by 4 cents per litre, aimed at funding infrastructure and environmental initiatives. However, it has compounded the pain at the pump for everyday consumers.
Supply Chain Challenges
New Zealand’s isolated geography makes it particularly vulnerable to disruptions in shipping and logistics. Ongoing congestion at major international ports, along with a shortage of transport vessels, has delayed deliveries and increased costs for fuel distributors.
Shift in Seasonal Demand
Entering winter, New Zealand typically sees a slight reduction in fuel demand. However, colder-than-expected temperatures in May 2025 led to higher use of diesel for heating and transport in agricultural sectors, tightening the supply further and supporting elevated prices.
Comparative: May 2024 vs May 2025 Fuel Prices in New Zealand
| Fuel Type | Average Price (May 2024) | Average Price (May 2025) |
|---|---|---|
| Petrol 91 | NZ$2.65 per litre | NZ$3.22 per litre |
| Petrol 95 | NZ$2.80 per litre | NZ$3.35 per litre |
| Diesel | NZ$2.35 per litre | NZ$2.95 per litre |
Government Responses and Public Reactions
The New Zealand government has acknowledged the burden on consumers and hinted at short-term relief measures. Talks around temporarily suspending the FED increase or introducing fuel subsidies are gaining traction. Meanwhile, public discontent is growing, with calls for urgent action to stabilize costs.
Strategies for Consumers to Manage Costs
Motorists are increasingly turning to fuel-saving strategies such as carpooling, using loyalty programs, and optimizing driving habits. Some are even accelerating the shift to hybrid and electric vehicles, a trend that saw significant momentum after fuel spikes in previous years.
Conclusion
Fuel prices in New Zealand are rising sharply in June 2025 due to a complex mix of international market dynamics, currency fluctuations, domestic tax policies, and logistical issues. While relief may be on the horizon through potential government interventions, consumers and businesses must adapt to the current high-cost environment. Understanding the underlying causes empowers individuals to make informed decisions during this challenging period.
