New Zealand switched on its first dedicated strategic diesel reserve this week, with Prime Minister Christopher Luxon opening three refurbished storage tanks at Marsden Point in Northland. The government is calling it a milestone for fuel security. The opposition and some analysts are asking whether renting nine days of diesel from a private company is the right way to protect the country from the next supply shock.
Luxon was joined by Finance Minister Nicola Willis and Associate Energy Minister Shane Jones at the former refinery site on Monday to mark the completion of the tanks, which are now holding about 93 million litres of diesel. That is roughly nine days of the country’s average diesel use. The largest of the tanks the Prime Minister turned on measures 76 metres across, about one and a half times the width of the Beehive, according to operator Channel Infrastructure.
The reserve is the government’s answer to a problem that has hung over the country since the Marsden Point oil refinery shut in 2022. Once it closed, New Zealand went from refining much of its own fuel to importing almost all of it as finished product. That leaves the country heavily exposed to shipping delays, price spikes and conflict in the Middle East, all of which have been in sharp focus during the recent oil price surge tied to the war involving Iran.
To build the reserve, the government committed $21.6 million from the Regional Infrastructure Fund earlier this year to recommission tanks that had been sitting idle. Under the deal, Channel Infrastructure stores the diesel on the Crown’s behalf and is paid about $1.2 million a month in fees, with the arrangement running to the end of 2027. Shane Jones has described diesel as the lifeblood of the economy, pointing to its role in trucking, farming, construction and the machinery that keeps freight moving.
The company delivered the tanks in about nine weeks, a job that would normally take 18 to 24 months. Channel chief executive Rob Buchanan said the project did not exist three weeks before work began and the team delivered the assets safely and on time nine weeks later. Alongside the diesel tanks, Channel also completed 30 million litres of new jet fuel storage for Z Energy, enough for roughly 10,000 flights between Auckland and Wellington.
For the government, the reserve is proof that its regional fund can move quickly when it matters, and evidence that it is taking fuel resilience seriously after years of warnings. Ministers also point to Channel’s wider plans for the site, which include an energy precinct with a proposed biodiesel plant and the promise of thousands of construction jobs in Northland over the coming years. The company says the broader vision could support around 20,000 construction roles as it turns a closed refinery into what it calls a terminal for the future.
The critics are less impressed by the headline numbers. Nine days of diesel is a thin buffer against a serious and prolonged disruption, and it does nothing to restore the refining capacity the country gave up. New Zealand is meant to hold the equivalent of 90 days of net oil imports under its International Energy Agency commitments, an obligation it has struggled to meet for years, in part by counting fuel still on ships heading here. A domestic reserve of nine days sits well short of that mark and only covers one fuel type.
There is also the question of who benefits. Some commentators have noted that the taxpayer is paying to refurbish and rent tanks owned by a listed company that stood to gain from the deal, rather than owning the storage outright. Over the life of the current contract the monthly fees add up to tens of millions of dollars on top of the initial recommissioning cost. Supporters counter that renting existing infrastructure is far cheaper and faster than building new tanks from scratch, and that the Crown avoids being locked into owning ageing assets it would then have to maintain.
Fuel security has quietly become one of the more consequential debates of this term. The closure of the refinery was a commercial decision made by its private owners, but the fallout has landed squarely on the government, which has had to weigh energy resilience against the cost of intervening in a market it does not control. The diesel reserve is a modest and pragmatic step rather than a return to the days of a working refinery, and how far it goes depends on the kind of crisis it is eventually tested against.
Whether nine days is reassurance or a warning is likely to be argued over well into the election campaign, with energy costs, resilience and the price at the pump all shaping how voters feel about the direction of the country.
