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 prolonged shutdown.
Z's chief executive, Mike Bennetts, told BusinessDesk the impact of a global collapse in refining margins, exacerbated by the costs associated with a longer than anticipated shutdown at the refinery in March and April, would cost the NZX-listed fuel distributor between $10 million and $15 million, but that those losses were being clawed back as much as possible at the petrol pump.
Figures for retail importer margins - a proxy for profit margins at the petrol station pump - rose to 29.4 cents per litre for petrol and 34.4 cents per litre for diesel in the June quarter, compared with 27.2 cents and 29 cents respectively in the March quarter, according to the Ministry of Business, Innovation and Employment.
The company has not altered its profit guidance for the year of earnings before interest, tax, depreciation, amortisation and changes in the value of financial instruments of between $220 million and $240 million.
As owner of 15.6 percent of New Zealand's only oil refinery, Z is caught by arrangements that require refinery shareholders to top up the refinery's operating costs if its Gross Refining Margin falls below US$3 a barrel. In the March and April this year, Refining NZ reported negative GRM's of US$2.72, exposing Z to a monthly cost of around NZ$3.2 million in the three months to June, said Bennetts.
