"This means our new store dedicated to serving online shoppers is more important than ever."
The new 8800sq m eStore's layout is organised based on sales data to increase picking efficiency.
And while it looks like any other supermarket with a butchery, bakery and shelves lined with products, no customers are allowed in-store.
Instead, a team of 200 personal shoppers, including 105 new to Countdown and 94 transferred from other stores, will run the eStore.
Delivery trucks will operate daily between 6am and 7pm, with staff replenishing stock - when orders are not being packed - with 25,000 products.
It will service delivery orders for Countdown stores in Mt Wellington, St Johns, Three Kings, Mt Eden, Botany, Manukau City Mall, Meadowlands and Manurewa.
Online pick-up orders will continue to operate, with increased windows available at each store due to delivery orders being moved to the eStore.
Copland said it was thought increasing Countdown's delivery capacity would triple the number of pick-up orders processed at affected stores.
"This is crucial in these challenging times when we know so many people are relying on online shopping."
Meanwhile, the supermarket chain has also partnered with Boston-based eGrocery company Takeoff Technologies to help in-store shopping.
