Four Square Bluff is a community supermarket at 54 Gore Street in Bluff, at the southern tip of the South Island. It is owned by Bridget and Jimmy. The store is known for seafood brought in directly from the boat, and for Bluff oysters during oyster season, which is the local catch that gives the town its name. It also has an on-site butcher, a hot food cabinet and a wide product range. The store says its scones are the biggest you have ever seen.
The store sponsors the local school, the rugby club and events such as Rangitahi Zone. The seafood and oysters are the reason many people in Bluff and beyond come in, and the on-site butcher and hot food cabinet mean a full shop is possible in one place.
