MikeAqua:unlikely as the distance most people will have to travel will offset the saving of the fuel tax. so you will end up paying more for the false economy.
Services stations just over the border will do well out of a regional fuel tax.
if you live close to the border it may work in your favour but for people in auckland its self unlikely
Agreed. three cents / litre for a 35L vehicle amounts to barely a dollar....which would be about about 45% of a litre.....or about 4-5km on a flat road with no wind (rough average of smaller and larger vehicles). Maybe it would matter for a PHEV that can roll down and back on EV power...then use the petrol elsewhere. But then why take half an hour to save $1? Waste of time.
Not worth it.
