Time is ticking to fill up, before the fuel tax returns.

The Government's relief package ends tomorrow, meaning petrol prices will rise around 29 cents a litre including GST.

It'll still be substantially less than the peaks seen after Russia's Ukraine invasion in March last year which saw oil prices skyrocket.

Gull NZ General Manager, Dave Bodger told Kate Hawkesby sales have been up, rather than manic.

He says yesterday's sales were about 50 percent higher than usual, and expects today will be much like a regular pre-Christmas special.
