There have been sporadic shortages since September when the pipeline from Marsden Point leaked.
A false alarm that forced a shutdown of the pipeline for 12 hours a week ago has also slowed the flow of fuel.
The three major oil companies - Z Energy, BP and Mobil - have all been left short.
Z Energy spokesperson Georgina Ball said stocks of 95-octane were still low, particularly in the upper North Island, and diesel had been short at some Wellington sites.
Ms Ball said demand was due to drop from Christmas.
