Sue Chetwin: Grocery Action Group chair on the new Costco store planned for Drury - Heather du Plessis-Allan Drive

Costco's interest in New Zealand could be a good sign for our grocery sector. 

The big-box US retail chain's bought a large plot in the new Drury Town Centre for its second Auckland store. 

A Westgate branch opened three years ago. 

Grocery Action Group chair Sue Chetwin says Costco clearly sees profit potential in New Zealand. 

"It would be really good if a third or a fourth operator thought like that, but was willing to have a few more supermarkets so more people could benefit."
