-- The fuel price in New Zealand is driven by a mix of global and domestic factors, including the price of crude oil in US dollars, refining margins, international freight, insurance costs, the New Zealand dollar exchange rate, as well as the cost of distributing fuel around the country, and other wholesaler and retailer costs and margins, ANZ Research said in a Friday report.
The national weekly average price paid by consumers as of April 3 was NZ$3.41 per liter for petroleum products and NZ$3.53 per liter for diesel.
With the closure of the Marsden Point refinery in 2022, New Zealand's fuel supply shifted from importing a mix of crude and refined products to importing refined fuels only. The country's petrol demand has been relatively stable, while diesel demand has been trending higher.
The Asian oil refineries that supply New Zealand typically source the bulk of their crude oil from the Persian Gulf.
More than 98% of imported petrol in 2025 came from South Korea, Singapore, and Malaysia. Meanwhile, almost 90% of imported diesel and jet fuel in 2025 came from South Korea, Singapore, Japan, and Malaysia.
Diesel accounted for 59% of terajoule fuel end use in New Zealand in 2023, with petrol accounting for 41%. Road transport dominates fossil fuel use, followed by the agriculture and construction sectors.
