Petrol station Gull will temporarily drop the price of petrol by 12 cents, making the average price of 91 petrol $2.05 a litre across their stations.
Their prices will drop from 7am on Thursday until midday on Friday.
Gull spokesperson Rohan Mehta said it was about making the most of spring weather.
"Yes, petrol prices have reached record highs due to international oil prices soaring and the NZ dollar depreciating."
"With a 3.5 cents nationwide fuel excise tax waiting to come into effect from September 30, 2018, petrol is only set to break the current record high prices."
There is no maximum or minimum fill, but only North Island residents will be able to take advantage of the deal as Gull does not operate in the South Island.
