Supermarket between the airport and denerau - Nadi

We are taking a taxi from the airport to denerau to go out to the islands, and wanted to make a brief stop to buy some supplies such as bottled water. Does anyone know of a supermarket or similiar, along the road (can't remember the name of that road) between these two places?

Im sure the taxi driver can find one for you - Nadi is not a big town
