How New Zealand's Fuel Distribution Network Works — From Refinery to Forecourt
Understanding how diesel and petrol reach New Zealand petrol stations explains why fuel quality, pricing, and supply are structured the way they are.
The Marsden Point Legacy
New Zealand's Marsden Point Oil Refinery, which processed imported crude oil into local petroleum products, ceased refining operations in 2022. Since then, New Zealand has been entirely dependent on imported refined fuel products — primarily sourced from Singapore, South Korea, and, historically, Middle Eastern refineries. This transition made New Zealand's fuel supply more exposed to international events, a vulnerability that became starkly apparent during the 2026 Iran conflict.
From Import to Pump
Refined fuel arrives in New Zealand by tanker, primarily at Marsden Point (now operating as an import terminal), Whangarei, and smaller ports. It is stored in terminal tank farms before being distributed to regional depots by pipeline (North Island) and coastal tankers, and then to individual petrol stations by road tanker. The entire supply chain from port to pump typically takes one to three weeks.
Why This Matters for Misfuel Recovery
Supply chain length means that fuel price movements at the international level take weeks to flow through to the New Zealand pump. Recovery costs — particularly towing, which runs on diesel — are sensitive to fuel price movements at every stage of the chain. When global oil prices move sharply, as they did following the 2026 Iran conflict, New Zealand's exposed import-dependent supply chain amplifies the impact on operating costs across the automotive services sector.
