Z Energy says margins on petrol and diesel have risen in recent months because fuel retailers who also own the Marsden Point oil refinery are trying to recoup up to $40 million they've had to pay to top up losses at the refinery caused by intense global competition and a

While most of that downward pressure on returns from the refinery reflected global over-supply of refining capacity, which is leading to refinery closures in Australia and further afield, the situation in New Zealand was exacerbated by the fact a planned shutdown for upgrades at Marsden Point continued for 22 days longer than anticipated.
That in turn led to the refinery stockpiling residues normally used in making diesel and fuel oil to the point where it ran out of storage capacity and forced to export residue in a low-value form at a cost to Z of between $4 million and $6 million.
"The importer margin is now higher than it has been because distributors sought recovery through their marketing margin," Bennetts said.
Unusually high exports can be seen in disclosures from Z today that show supply/export sales in the June quarter totaled $122 million, compared with $42 million in the same period last year, with some 60 percent of the increase attributable to forced exports of refinery residue.
While motoring advocates, such as the Automobile Association, were criticising the rise in retail importer margins, it reflected an attempt to recoup some of the losses suffered on the refinery operation, which is undergoing a $365 million major upgrade which, along with other incremental improvements, should improve GRM's by around US$1.76 per barrel once commissioned in December 2015.
The other refinery owners are BP (21.5 per shareholding), Mobil (17.4 percent), and Chevron, trading as Caltex (11.5 percent).
Bennetts acknowledged competing low-cost fuel retailer Gull, which imports all its fuel in refined form, is "cost-advantaged in this scenario because they import everything."
In Z's case, some 75 percent of its product comes from Marsden Point, which the industry in New Zealand has chosen to maintain and upgrade in part because of its importance to maintaining security of transport fuel supplies for the country.
Marsden Point remains one of the most competitive refineries in Australasia, producing fuels "at the top of the second quartile for its ability to process a complex variety of crudes, enabling it to gain more margin than others," said Bennetts.
The last time GRM's at the refinery had fallen below US$3 per barrel, sparking the "fee floor" provisions of its contracts with oil company owners, was in 1999.
