National petrol prices have fallen to $2 a litre for the first time in two and a half years.
BP and Z both claimed to have led the market this morning in reducing their national price for 91-octane petrol to 199.9c.
They have been joined at that price this afternoon by both Mobil and Chevron, which runs to Caltex brand.
But industry minnow Gull is asking what took them so long, saying it reduced its maximum price for 91-octane to that level a fortnight ago.
Gull's lowest price today is 184.9c in Rotorua and three of its stations in Botany, East Tamaki and Otara are selling the grade at 185.9c, says managing director Dave Bodger.
