Marsden Point
What is it?
Marsden Point was New Zealand's only oil refinery. Located near Whangārei in Northland, it operated from 1964 to 2022 — 58 years of turning imported crude oil into the petrol, diesel and jet fuel that kept New Zealand moving.
At its peak it produced 70% of NZ's petrol and 90% of its diesel. It also produced every drop of bitumen that went into our roads and supplied jet fuel so good that Australian Air Force tankers would cross the Tasman just to fill up.
In March 2022, the last flame went out. The refinery was decommissioned, dismantled, and converted into an import terminal. New Zealand has had no oil refinery since.
Where was it?
Marsden Point sits on the eastern shore of Whangārei Harbour in Northland — chosen in the early 1960s for its deep-water port, proximity to Auckland, low earthquake risk, and available industrial land.
A 168-kilometre underground pipeline — the Refinery Auckland Pipeline — ran from Marsden Point directly to the Wiri Oil Terminal in South Auckland, pumping up to 400,000 litres of fuel per hour at its peak. That pipeline still exists and is still used — but now to move imported refined fuel from ships rather than locally refined product.
Who owned it?
Marsden Point was originally built as a public-private partnership under the Labour government of Walter Nash in 1964 — designed specifically to reduce NZ's dependence on imported refined fuels after the vulnerabilities exposed by World War II.
Over the following decades, ownership shifted. In 1988, the Fourth Labour Government deregulated the petroleum sector and handed full control to the private sector. The refinery became owned by a consortium of multinational oil companies — BP, Shell, Mobil, Caltex and later Z Energy.
By 2021, the company operating it had rebranded as Refining NZ, later Channel Infrastructure. The major shareholders were Mobil/ExxonMobil (14.4%), Z Energy (12.9%), and BP (8.5%).
Why did it close?
The short answer: it was losing money.
By 2020, Marsden Point was struggling against competition from giant modern refineries in Asia — facilities ten times its size, running at far lower cost per barrel. Global refining margins had been falling for years. Then COVID-19 hit, demand for fuel collapsed, and the economics became impossible.
In August 2021, shareholders voted — 99% in favour — to stop refining and convert to an import terminal. It was cheaper to buy already-refined fuel from Singapore and South Korea than to make it themselves.
The then-Labour Government under Jacinda Ardern declined to intervene. Energy Minister Megan Woods rejected proposals for government loans or subsidies, stating there was no strong case on fuel security grounds.
Refining ended on 31 March 2022. Decommissioning crews moved in almost immediately — cables cut at ground level, heat exchanger bundles stripped out, storage tanks emptied. By 2024 the process was complete.
How does this affect NZ now?
Without Marsden Point, New Zealand imports 100% of its refined fuel — petrol, diesel, jet fuel, everything.
That fuel comes primarily from refineries in Singapore and South Korea. Those refineries source most of their crude oil through the Strait of Hormuz. When global events disrupt that route — as happened in 2026 with the Iran conflict — NZ has no buffer, no fallback, and no ability to refine its own fuel.
A country with a functioning refinery has options. It can source crude oil from different regions, refine locally, and reduce its exposure to disruptions in the refined fuel market. NZ lost those options in 2022.
The 2026 fuel crisis made this visible in a way that was impossible to ignore. Prices spiked. Stations ran dry. The government scrambled.
Can we reopen it?
No — not quickly, and not cheaply.
Channel Infrastructure CEO Rob Buchanan has been unambiguous: "There is no part of the former refinery that can be restarted. There's no big green lever."
The site has been fully decommissioned. All cabling was cut at ground level. Equipment was stripped out and recycled. What remains are empty tanks, silent towers, and infrastructure that would need to be entirely rebuilt.
Rebuilding a functioning refinery at Marsden Point would cost an estimated $4.9 to $7.3 billion and take at least six years — and that assumes a specialist workforce that has already moved on to other industries.
The government launched a feasibility study in 2024. In 2026, that conversation became urgent. But even in the best-case scenario, a rebuilt Marsden Point would not be operational until the early 2030s at the earliest.
What about the future of the site?
Channel Infrastructure — which still owns and operates the Marsden Point site as a fuel import terminal — has signaled interest in transforming it into an energy precinct for the future.
Options being considered include expanded fuel storage, synthetic aviation fuel production, green hydrogen facilities, and methanol import capability. These aren't refinery operations — but they represent a path toward rebuilding some of the energy sovereignty NZ lost when the refinery closed.
Whether that happens depends on government investment, commercial appetite, and how seriously NZ takes the lessons of 2026.
The big question
Was closing Marsden Point the right decision?
At the time, the commercial case was clear. It was losing money. Cheaper fuel was available overseas. The government of the day saw no compelling reason to intervene.
In hindsight, the closure removed a layer of protection that NZ didn't fully appreciate until it was gone. The decision prioritized short-term economics over long-term resilience — and when the global system was stressed, NZ felt it immediately and acutely.
It wasn't one government's fault. The deregulation that set the path began in 1988. The closure decision was made by private shareholders in 2021. Multiple governments across thirty years made choices that led here.
The question now isn't who to blame — it's what NZ does next.
Commonly asked questions
"Why didn't the government stop the closure?" The government at the time reviewed it and decided there wasn't a strong enough case for intervention. The refinery was privately owned — the shareholders made the call. The government chose not to override that with subsidies or loans. In hindsight that's being heavily questioned.
"Can't we just reopen it?" No — not quickly. The site has been fully stripped and decommissioned. There is no big green lever to pull. Rebuilding would cost up to $7 billion and take at least six years. It's a long-term conversation, not a short-term fix.
"Who's to blame?" No single government or company. The path to closure started with deregulation in 1988, ran through thirty years of private ownership, and ended with a shareholder vote in 2021. Multiple decisions across multiple governments got us here.
"Why did we even have a refinery in the first place?" Because after World War II, NZ understood the danger of being entirely dependent on imported fuel. The refinery was built deliberately to give NZ energy sovereignty. That lesson got forgotten over time.
