Fuel retailer Gull has committed to not increase prices at its outlets until the end of the week.
The moves comes after an attack on Saudi Arabian oil fields led to large spike in the price of oil - and warning petrol in New Zealand could surge to up to $3 a litre
Gull chief executive Dave Bodger said local fuel prices usually followed prices in the international market.
"The long-held rule of thumb of a $US1 increase in the price of a barrel of crude oil equates to a cost increase of 1 New Zealand cent per litre still holds," he said.
