Mister Minit Merivale Mall is a repair-and-service shop at Shop 6A Merivale Mall, 189 Papanui Rd, Merivale, Christchurch, with a 4.5 Google rating. It is the local branch of the Mister Minit chain, long known around Australasia for shoe repairs, key cutting, watch batteries and engraving.
Shops of this kind earn their keep on small jobs done while you wait — a watch battery fitted in minutes, a spare key cut on the spot. The quieter value is the cobbling: resoling good shoes or rebuilding heels costs a fraction of a new pair and often leaves them more comfortable than before. It is worth asking whether rubber or leather soles suit the shoe, since rubber grips better on wet pavements. If a cut key doesn't turn smoothly, have it recut before leaving.
For locals running errands along Papanui Rd, having that counter inside Merivale Mall makes it easy to drop off a repair and keep shopping.
