Sunshine Corner Market is a produce market on the corner of Hills Road and Westminster Street in Mairehau, Christchurch, holding a 5.0 rating from 15 Google reviews, with regulars praising the fresh produce, reasonable prices and the friendly couple who run it; you'll find it on Facebook rather than a dedicated website.
Independent produce markets live or die on freshness, and stock shifts with the seasons and with each delivery, so what looked good on Tuesday can be gone by Friday. Regulars shop little and often, keep an eye out for whatever is at its peak, and aren't shy about asking what came in that morning. Because these shops are usually owner-operated, the person at the till knows the stock personally and can point you to what's best today, guidance the big supermarkets rarely match.
For Mairehau locals after fresh groceries without a supermarket trek, it sits where the name promises, on the corner of Hills and Westminster.
