"Deployment on this scale, with such a large existing infrastructure makes 'Your Warehouse' a breakthrough technology and the first of its kind in New Zealand," said Sush Mobile managing director Sheenu Chawla.
The app is now available for download on Android and iOS.
Last year The Warehouse announced it had paid $33 million for a 51 per cent stake in Hamilton-based online retailer Torpedo7, in a push to increase its online presence.
Two weeks ago the company also announced it would set up its own financial services operation, and raised $100 million from institutional investors to help fund the push.
Other functions of 'Your Warehouse' include:
• Ability to view and shop special offers and weekly deals;
• Convenient search and sort by category;
• A wishlist so users can save their favourite products and receive alerts when they go on sale;
• Store locator, opening hours, contact details and driving directions;
• Single login across the app and the desktop site.
