New Zealand Post and The Warehouse are teaming up to launch Shipmate - a free delivery service in which, for a single payment, shoppers will get an unlimited number of purchases with no delivery fee from participating retailers.
The Warehouse Groups brands - The Warehouse, Noel Leeming, Torpedo 7 and Warehouse Stationery - are all participating in the model, which is similar to Amazon Prime.
New Zealand Post head of customer strategy Brendan Thawley said the service would create value for its customers.
"We're excited about this new innovation in the New Zealand market and are delighted that four of The Warehouse Group's brands will be the first to offer the service to their customers," Thawley said.
"A shared problem for both parcel senders and receivers is that often consumers want to buy small things online but the cost of shipping is too high relative to the purchase.
