Petrol prices have fallen for the second time in three days, Shell leading the way with a second 4c a litre drop this morning.
BP, Caltex and Gull also cut prices at the pump by 4c.
Today's cuts bring the total fall in price since Saturday to 8c a litre.
Unleaded 91 fuel now costs around $1.549. Diesel remained unchanged around 99.9c per litre.
Today's price drop reflected a decrease in cost in the international price of refined petrol and a strong New Zealand dollar, Shell said.
