Unusual that Z would drop for a Gull Promotion day.
However if you are within 30km of Z Hewletts Road, might pay to TopUp your Sharetank fuel.
While it might not be the cheapest fuel in New Zealand, it is a very good price once Gull 12cpl finishes tomorrow @ Midday.
Don't forget that a further 25/28cpl will be added back to ALL fuel in 2023.
That's the strangest deal title I've seen in a while.
