NZ bolsters emergency oil stocks backed by offer of Marsden Point storage

New Zealand pre-ordered more oil stocks just before Russia invaded Ukraine, increasing government reserves this month – at a critical time.

The Government and New Zealand fuel companies together hold more than 1.7 million tonnes of oil in tanks, ship holds, and international ticket contracts acquired just in time for last week's international action.

The Ministry of Business and Innovation told Newsroom last night that the new "tickets" were purchased at January prices, before world governments agreed to ban hoarding any more petroleum. "The International Energy Agency has asked member nations to delay rebuilding stockholding to help with its energy security measures," a ministry spokesperson said.

Brent crude oil was selling for US$85 a barrel when the Government agreed the purchase in mid-January; two month later as Russian missiles rained down on Kyiv, the price had soared above $120 a barrel. 

Back in mid-January, diesel was being imported at NZ 95c/litre and regular petrol at 93c; now the import prices are up to NZ$1.36 and $1.22 respectively – and pump prices have broken new records.  

After agreeing last week to release 65,000 tonnes of oil as part of an international deal to support global fuel supply, the Government still holds 837,000 tonnes of oil in tickets contracts – effectively options to release that oil. 

It agreed last week to release tickets to 184,000 barrels of crude oil held in Spain, and nearly 299,000 barrels of diesel held in the UK. This is unprecedented – the second such emergency release agreed by the International Energy Agency in a month – though some of the 31 member nations refused to take part.

Channel Infrastructure has shut down the Marsden Point oil refinery but its chief executive Naomi James told Newsroom Pro managing editor Jonathan Milne, on an episode of Pro Talks, that the company's tanks were now available to store reserves of refined oil to tide NZ through the Ukraine crisis and beyond.

"One of the changes with the transition is we're less dependent on a single refinery than we were previously. And our supply will be coming from a range of of refineries around the Asian region." – Naomi James, speaking on Newsroom Pro Talks

That's because, beyond the 837,000 tonnes held by the Government in overseas ticket contracts, New Zealand's big fuel companies hold about 900,000 tonnes physically in tanks on New Zealand soil, and on ships bound for New Zealand.

That means that this month, for the first time in a year or more, New Zealand is complying with its international agreement to hold more than 1,448,000 tonnes of oil in reserve –  enough petrol, diesel and jet fuel to keep New Zealand running for 90 days.

The big fuel purchase, which nearly doubled the Government's stocks this month, was timed as a response to the closure of the refinery.

But it is also timely because of the subsequent international deal to stop buying any more stockholdings. In the last two releases after collective action by the International Energy Agency, not all countries have released oil stocks, in spite of this being an authorised agency collective action.

 “There has been a great deal of volatility in global oil markets since the invasion and this further action, coupled with the United States’ move to release 180 million barrels of oil over the next six months, will help to provide some certainty to the market." – Megan Woods, Energy Minister

"Some declined because they have argued that the current emergency does not meet their legislative requirements for release of oil stocks," the MBIE spokesperson said.

Energy Minister Megan Woods said New Zealand's second release of emergency oil stocks showed its commitment to helping stabilise world energy markets. “There has been a great deal of volatility in global oil markets since the invasion and this further action, coupled with the United States’ move to release 180 million barrels of oil over the next six months, will help to provide some certainty to the market," she said.

Fuel companies will now import New Zealand's refined oil from a range of countries including Singapore, Korea and Japan, which James said would make the country less vulnerable to fuel shortages.

Channel Infrastructure – as the former refining company is now known – has already done deals with its biggest customers and shareholders, Mobil, Z Energy and BP. "We have signed agreements with the oil companies for 280 million litres total product storage," James said.

Of that, 180 million litres is shared by the companies, and 100 million litres is private. "To put that into context, the 100 million litres private is equivalent to around four days cover for New Zealand, based on 2019, pre-Covid demand. That's with capacity to increase available storage if it were required."

"The shift is really that we're sourcing it from a range of refineries around the world," she said. "Our customers primarily source from refineries in Asia, to supply New Zealand. That was already occurring for about 30 percent of our fuel supply, even while we had the refinery operating. So one of the changes with the transition is we're less dependent on a single refinery than we were previously. And our supply will be coming from a range of of refineries around the Asian region."

"We should be able to count stock on water as part of our overall stockholding levels as Z takes control of the cargo from when it is loaded, so can direct the vessel as needed – that is, speed up, slow down, take another route." – Julian Hughes, Z Energy

New Zealand's biggest fuel company, Z Energy, is both Channel Infrastructure's biggest shareholder and the biggest customer for its imported refined oil.

Julian Hughes, Z Energy's general manage of supply, said two industry vessels had already successfully discharged at the Marsden Point import terminal, since the closure of the refinery. The fuel could then be sent down Channel's RAP pipeline to Wiri, or loaded into tanks or trucks. Three more oil tankers were scheduled to discharge this week, he said.

At any one time, Z calculated it would have four shipments on the water, Hughes said, which equated to 185 million litres or 148,000 tonnes of product. With an average voyage time of 22 days, there would one Z vessel arriving into New Zealand about every 5 1/2 days.

"We should be able to count stock on water as part of our overall stockholding levels as Z takes control of the cargo from when it is loaded, so can direct the vessel as needed – that is, speed up, slow down, take another route," Hughes said.

Z Energy supply general manager Julian Hughes says the company typically targets stocks of petrol and diesel at around 50 percent of tank capacity, which would cover the company's needs for 35 to 40 days. Photo: Supplied

"Z’s analysis shows that if you count stock on water (all tankers, not limited to territorial waters or those in the Exclusive Economic Zone) we could comfortably meet the Government’s proposed minimum fuel stockholding requirements."

He said Z typically targeted stocks of petrol and diesel at around 50 percent of tank capacity, as this was is a good equilibrium between a safe and reliable supply chain, and efficient operating. That would cover the company's needs for 35 to 40 days, including the stock on the water.

BP spokesperson Gordon Gillan was less forthcoming. He would say only the company had no significant changes to its average stock holdings under the import-only model. "BP is well placed to ensure we continue to provide supply security for all our customers throughout New Zealand," he said. "We have a dedicated local supply team and are experts in reliably sourcing quality product from international refineries and terminals for our nationwide terminal infrastructure."

There have been calls from Social Credit leader Chris Leitch and some unions to keep Marsden Point refinery open, to refine Taranaki crude oil. But Naomi James said it was not viable to refine New Zealand's small quantities of light Taranaki crude oil, as the refinery was designed for much bigger runs of imported heavy crude oil.
