Pak'n Save South Dunedin's new petrol pumps. Photo by Craig Baxter.
The pumps went into operation yesterday.
They are the third set to be installed at Pak'n Saves in the South Island. The others are in Invercargill and Christchurch.
Pak'n Save South Dunedin co-owner Chris McDonald said the fuel pumps were "flat out" yesterday.
The pumps are self service, and customers can pay with a card or with cash.
Petrol would be the same price as at other stations but Pak'n Save customers could save up to 6c a litre with fuel dockets from the store.
Mr McDonald said attendants would be at the site for the next few weeks to help people with the self-service system.
