Asian Value Mart is a supermarket at 230 Riccarton Road in Upper Riccarton, Christchurch, open 9am to 9pm every day of the week. It's rated 4.4 from 50 Google reviews, with updates on its Facebook page, though a number of reviewers mention slow or offhand service at the counter.
Asian grocers earn their keep on the staples: rice in bags the big chains can't match for price, soy and fish sauces, noodles, frozen dumplings and snacks you won't find in a mainstream supermarket, plus fresh greens like bok choy. Everyday Western groceries can cost more at these shops, so the trick is a dedicated staples run rather than a full weekly shop. Labels may be only partly in English — asking is the quickest way to learn what an unfamiliar sauce or pickle is for.
On Riccarton Road's busy strip of Asian food shops and eateries, those long daily hours make it a handy local stop.
