Harrington Dairy is a neighbourhood supermarket on Peverel Street in Riccarton, Christchurch, just off the busy Riccarton Road shopping strip, and it holds a 4.0 Google rating. A good dairy earns its place through convenience: it is where locals duck in for a litre of milk, a loaf of bread or a cold drink rather than fighting the big supermarkets' car parks for two items. The better ones often keep long hours, stock the staples people run out of, and get to know regulars by face. In a suburb like Riccarton — students, flats and families close together — that quick top-up between bigger shops is the whole point of the corner store. Judge a dairy on its basics: fresh bread, a tidy chiller, easy access, and whether you can be in and out in five minutes. For anyone living or studying around Riccarton, having that quick stop a street back from the main road is a genuine everyday convenience.
