Petrol retailer Gull will run a 12-hour "discount day" today at five service stations that ran out of fuel during last week's price drop.
The company says it will be "spreading Christmas savings" to compensate those who missed out on the cut-price fuel last week.
The 12-hour sale price will be in place from 7am today.
Last week queues formed outside Gull petrol stations for the temporary 20 cent a litre price drop. But some sites were unable to keep up with demand and ran out of fuel, Gull said.
"While we were spreading Christmas savings last week some of our customers missed out through no fault of their own," Dave Bodger, general manager of Gull New Zealand, said.
