The Commerce Commission has given the green light to one of the biggest shake ups in the New Zealand fuel retail market in more than a decade, granting clearance on Friday 8 May 2026 for the merger of Gull New Zealand and the Nelson based fuel retailer NPD. The combined business will operate 240 sites stretching from Invercargill to Kaitaia and will buy roughly one billion litres of fuel a year, putting it firmly into third place behind Z Energy and BP, and ahead of Mobil at the retail level.
The deal will see both brands acquired by a new parent company called Astra Energy Group, owned 50 percent by the South Island Sheridan family, who already control NPD, and 50 percent by the Australasian private equity firm Allegro Funds, which has owned Gull since 2022. NPD chief executive Barry Sheridan will run the merged group. Despite the common ownership, both the Gull and NPD brands will continue to trade at the pump, and the companies say their existing low cost, mostly unstaffed forecourt model will not change.
The two retailers announced their intention to combine in December 2025, with the Commerce Commission opening a formal clearance process the same month and inviting submissions from competitors and consumer groups through to February. Although the regulator initially flagged concerns that the merger could blunt competition in regional retail markets and in the wholesale fuel supply that smaller independents rely on, it concluded after a five month investigation that the deal would not substantially lessen competition anywhere in New Zealand.
Commerce Commission chair Dr John Small said the watchdog had taken a careful look before signing off. In its decision the Commission said its investigation included “looking at the markets within which NPD and Gull currently operate and assessing whether there would still be adequate competitive alternatives post merger to constrain the new company’s ability to raise prices and reduce the quality of its service”. Small added that “following this work, we are satisfied that the proposed merger is not likely to substantially lessen competition in any market in New Zealand in which the parties compete, or are likely to compete in future”.
The Commission’s analysis turned heavily on the presence of the three majors. Z Energy, BP and Mobil between them still control the bulk of the country’s branded forecourts, refined fuel imports and commercial supply contracts. The regulator decided the merged Gull NPD business would remain “constrained in the retail and wholesale supply of fuel by the presence of other competitors, including the majors, as well as independent fuel suppliers” such as Waitomo, Allied Petroleum and the supermarket linked discount sites operated through Pak’nSave and New World.
From a consumer point of view the story is more interesting than a routine merger clearance. Gull and NPD have spent years pulling pump prices down in the regions where they operate. Gull’s Mount Maunganui import terminal, which it owns outright, has been credited with putting downward pressure on petrol margins right across the upper North Island. NPD’s South Island heartland of Nelson, Marlborough, Canterbury and Otago has seen similar discounting, often a few cents below the majors at any given time. Combining the two means the cheapest brand in the South Island and the cheapest brand in the North Island will now share buying power, logistics and a national fleet card offering aimed at trucking and farming customers.
NPD chief executive Barry Sheridan told media after the clearance that “Gull and NPD joining together will make our ability to support lower fuel prices in NZ even stronger”. The Automobile Association indicated earlier in the process that it expected the deal to support lower retail prices, on the basis that scale should let the new group negotiate harder with refiners and shipping suppliers.
The political backdrop matters here. New Zealand has been running a tight petrol and diesel market since the closure of the Marsden Point refinery in 2022, and the country has just spent April nervously watching offshore reserves climb to 58 percent of its national fuel stockpile. Channel Infrastructure, which owns the Marsden Point import terminal, this week lifted its full year profit guidance to as much as $105 million as the fuel crisis drove tank throughput higher. A bigger, better resourced independent challenger that can import its own product through Mount Maunganui rather than relying on competitor terminals is exactly the kind of structural change that the OECD and the Commerce Commission have both said the New Zealand fuel market needs.
For Allegro Funds the merger is also a typical mid market private equity play. The Sydney based firm bought Gull from Caltex Australia in 2022 for around A$560 million, refreshed the brand, expanded the network from about 113 sites to 130, and now folds it into a larger national platform alongside the Sheridan family’s South Island business. The combined group will not be listed on the NZX, and the parties have not disclosed the value of the new transaction.
The next steps are operational. Astra Energy Group will need to integrate two head offices, two technology stacks and two fleet card systems, while keeping the Gull and NPD brands separate at the pump. Industry observers will be watching to see whether the new owner moves first to lift prices to fund integration costs, or whether it stays disciplined and uses its scale to keep undercutting the majors. The Commerce Commission has not imposed any conditions on the clearance, but has the power to revisit the deal if competition concerns emerge in the future.
