Overview
Gull New Zealand is a New Zealand petroleum-distribution business and retail petrol-station chain. It operates under the Gull brand and is one of the country’s largest fuel retailers, with the reference material describing it as the third-largest operator and reporting 113 locations, including 45 in Auckland. Its business is centered on the importation, distribution, and retail sale of transport fuels through branded service stations rather than on vehicle manufacturing, refining, or a broad consumer-goods portfolio. The New Zealand operation was established in 1998 by Australian businessman Fred Rae as the local arm of Gull Petroleum, a Western Australian petrol company founded in 1976 by Keith Mitchell, Mark Quackenbush, and Terry Lockwood. Rae had invested in the Australian business in 1978 and became its controlling shareholder in 1994. Gull New Zealand opened its first retail outlet in Frankton, Hamilton, in 1999, beginning a period of network expansion that eventually made the brand a significant independent competitor in the New Zealand fuel market. Gull’s retail proposition has historically been associated with competitive pump pricing and a relatively lean service-station model. The company has also used fuel innovation and alternative-fuel initiatives to differentiate itself. In 2010 it introduced Diesel Max, a diesel fuel containing a five-percent biodiesel blend. The product was initially supplied by New Zealand producer Environ Fuels and was available at five of the company’s roughly 100 stations. In 2014 Gull changed to an Australian-sourced biodiesel blend, citing problems with local supply. The Diesel Max brand was discontinued in 2020 because of cost, scalability, and import-supply-chain difficulties. Network growth continued through the late 2010s and early 2020s. Gull opened its first South Island location in 2019 and reached its 100th New Zealand site in East Tāmaki, Auckland, in March 2021. The centenary-site opening included a highly visible price promotion that reduced fuel prices by 100 cents for the first 100 minutes, reinforcing the brand’s price-led market identity. Ownership has changed several times. In December 2016, Gull’s then-owner agreed to sell the New Zealand business to Caltex Australia, which later adopted the Ampol name; completion took place in July 2017. Ampol subsequently sought to acquire Z Energy, and competition-approval considerations led it to sell Gull. In 2022 Ampol agreed to sell the business to Australian investment firm Allegro Funds for A$572 million, while retaining a five-year fuel-supply arrangement. The transaction was intended to remove a potential competition obstacle to Ampol’s proposed Z Energy acquisition. The reference material also reports that Gull and NPD announced plans in December 2025 to merge their New Zealand operations, subject to regulatory approval, and that the Commerce Commission approved Astra Energy Group’s acquisition of the parent companies of Gull and NPD in May 2026. Under that reported structure, the two businesses were to merge while retaining separate customer-facing brands. Gull therefore remains an active New Zealand fuel retailer whose identity is built around network scale, price competition, and convenience-oriented petrol-station operations.
History
Gull New Zealand is the New Zealand arm of the Gull petroleum business. The wider Gull business began in Western Australia in 1976, when Keith Mitchell, Mark Quackenbush, and Terry Lockwood established a petrol company. Real estate agent Fred Rae invested in the business in 1978 and later became its controlling shareholder in 1994. Rae established Gull New Zealand in 1998 as the group’s New Zealand operation. The New Zealand business opened its first retail outlet in Frankton, Hamilton, in 1999. It subsequently developed a network of branded petrol stations and became a substantial competitor in the domestic fuel-retailing market. Its operations have focused on selling petrol and diesel through retail forecourts, with the business generally associated with competitive pricing and expansion into new regions. Gull introduced an alternative-fuel initiative in 2010 with Diesel Max, a diesel product containing a five-percent biodiesel blend. The initial supply came from New Zealand producer Environ Fuels, and the product was offered at five of the company’s approximately 100 stations. In 2014 Gull moved from locally produced biodiesel to an imported blend from Australia, attributing the change to local supply problems. The Diesel Max product was discontinued in December 2020 because the company considered its cost, scalability, and import supply chain unsuitable for continued operation. The same year, Z Energy announced the closure of its own biodiesel factory, citing economic difficulties. Ownership changed in the second half of the 2010s. In December 2016, Fred Rae agreed terms to sell Gull New Zealand to Caltex Australia, later renamed Ampol. The transaction was completed in July 2017. Gull continued to expand geographically, opening its first South Island location in 2019. In March 2021 it opened its 100th site at East Tāmaki in Auckland. The launch was accompanied by a short-term promotion cutting 100 cents from fuel prices for the first 100 minutes. Ampol’s ownership became relevant to its proposed acquisition of Z Energy. In 2021, the ownership of Gull was identified as a possible competition issue in that transaction. Ampol ruled out floating Gull’s shares in February 2022 and soon afterward agreed to sell the business outright to Allegro Funds for A$572 million. The sale was designed to support regulatory approval for the Z Energy acquisition. Ampol also agreed to supply Gull with petrol for five years after completion, while Allegro indicated that it was interested in further expansion. The reference material reports a further proposed consolidation in December 2025, when Gull and NPD announced plans to merge their New Zealand operations subject to Commerce Commission approval. It also reports that, on 8 May 2026, the Commerce Commission approved Astra Energy Group’s acquisition of Gull’s parent company, GNZ Holdco Limited, and NPD’s parent, NPD Group Investments Limited. The reported plan was to combine the two businesses while maintaining the Gull and NPD brands separately. Gull’s historical development consequently reflects both organic station-network growth and repeated changes in ownership within the Australasian fuel sector.
