Shantil Prema's shop in Grey Lynn, Auckland, is one of many small shops that sell liquor. Liquor licensing is an example of regulation of an economic activity by law. A variety of regulations govern the sale of liquor, in particular the places and times at which liquor can be sold. A proposed law change, in response to the killing of a liquor store owner in 2008, would require a store selling liquor to be at least 150 square metres in size. That would effectively end the sale of liquor by many dairies and convenience stores such as Prema's and possibly put them out of business.
