Bay of Islands motorists will soon enjoy the "Gull effect" with petrol prices expected to plummet when a cut-price petrol station opens in Waipapa.
Gull New Zealand is planning to open an unmanned petrol station off Klinac Lane in March. Earthworks are already underway opposite The Warehouse.
Even motorists who don't tank up there are likely to reap the benefits of what the AA calls the Gull effect. Wherever Gull has opened for business, existing service stations have dropped their prices to stay competitive.
Motorists in Kerikeri, which is served by a BP/Caltex duopoly, have long grumbled about relatively high petrol prices.
Whangarei, by contrast, has some of the country's lowest petrol prices - a result not of the proximity of Marsden Pt oil refinery, but of a Gull station in Otaika. The price difference between Kerikeri and Whangarei is at times as high as 20 cent a litre.
