Discount fuel retailer Gull will cut the ribbon on its first South Island site on Wednesday.
The rollout begins in Maheno, south of Oamaru, followed by Gore later in October.
General manager David Bodger told The AM Show Maheno was chosen because it's a site that could be opened rapidly.

The company has matched its lowest North Island price for Wednesday's opening - $1.91 per litre for unleaded 91 fuel. In comparison, petrol prices down the road in Oamaru remained about $2.15.
Bodger said Gull's cheaper prices are due to "attitude".
"That's what the Gull brand's been for 21 years, and will continue to be - we've got to bring value."
Following the Gore opening, Bodger said the company would look at opening in the greater Christchurch area and other parts of the South Island.
