The price of petrol at a large number of stations remains above the $3 mark, Newshub reports, despite a 25c cut in gas taxes overnight. Among the most expensive is the BP petrol station on Jervois Rd in the Auckland suburb of Ponsonby, which has 91 for $3.37, according to price-tracking app Gaspy. That’s significantly higher than Auckland’s cheapest price in North Shore, at Gull Albany for $2.64.
