A major attack on a key gas facility in the Middle East is now hitting New Zealand where it hurts most, at the petrol pump and in the weekly shop.
Oil prices have jumped sharply following strikes on Iran’s South Pars gas field, one of the most important energy sites in the world. At the same time, disruption in the Strait of Hormuz, a critical shipping route, has slowed the flow of oil and gas to global markets.
For New Zealand, the impact is immediate.
Petrol prices have pushed past $3 a litre in many areas, and economists warn they could climb much higher if the situation continues.
New Zealand no longer refines its own fuel. Since the closure of Marsden Point, the country relies entirely on imported petrol and diesel.
That means global shocks flow straight through to local prices.
Most of New Zealand’s fuel comes from refineries in Asia, which depend heavily on crude oil from the Middle East. When supply is disrupted, costs rise everywhere.
Even if the conflict eases, supply may take months to recover due to damaged infrastructure and halted production.
The first impact is being felt at the petrol pump.
But fuel is only part of the story.
Higher energy costs flow through the entire economy.
For many households, that means an extra $40 to $70 a week in basic living costs.
| Household Expense | 2026 Increase | Driver of Increase | Estimated Weekly Impact (Average) |
| Transport Fuel | ~20% | Global Oil Shock / South Pars | +$25.00 – $40.00 |
| Property Rates | 7.9% | CRL Costs / Infrastructure | +$6.16 |
| Public Transport | 5.1% | Annual Review / Operating Costs | +$3.50 |
| Electricity/Gas | ~10% | Domestic Gas Scarcity | +$5.00 |
| Food/Groceries | 4.5%+ | Logistics / Fertilizer Costs | +$15.00 – $25.00 |
Auckland is feeling the squeeze more than most.
Households are already dealing with:
Add higher fuel prices, and the pressure on household budgets is intensifying.
Long commutes and traffic congestion make the impact worse, as drivers burn more fuel in stop-start conditions.
This is not just a consumer problem.
Fuel is a core cost for many industries, including:
As those costs rise, businesses pass them on. That is how higher oil prices turn into broader inflation.

New Zealand’s primary sector is particularly exposed.
Farmers are dealing with:
At the same time, export routes through the Middle East are disrupted, adding delays and extra costs.
For perishable goods like meat and produce, delays can reduce quality and value.
Economists warn this could push inflation higher again, just as it had started to ease.
If fuel prices stay elevated:
This creates a knock-on effect across the entire economy.
Officials say New Zealand’s fuel supply remains stable for now.
The country holds several weeks of fuel reserves, and supply chains are still operating.
However, the system depends on long shipping routes and a small number of suppliers. Any further disruption could tighten supply quickly.
This crisis highlights a deeper problem.
New Zealand is highly exposed to global energy shocks.
That leaves the economy vulnerable when global supply is disrupted.
Much depends on how long the conflict lasts.
If tensions ease quickly, prices may stabilise.
If not, New Zealand could face:
For now, the impact is already being felt in households across the country.
And unless supply improves, it is likely to get worse before it gets better.
