An Auckland Pak'nSave has been charged for allegedly overcharging customers at the till.
The Commerce Commission alleges that on six dates during June and October 2018, Pak'nSave Mangere charged a higher price at the checkout for one or more items than what was advertised in-store or online.
Pak'nSave Mangere now faces 12 charges under the Fair Trading Act.
The charges arose after Commerce Commission staff conducted mystery shops to see if there were price discrepancies. After the alleged disparities were found, the issue was "immediately" raised with the supermarket's customer service team.
The staff returned the next day and repurchased the products, and found there were price discrepancies still occurring.
The Commerce Commission declined to make any further comment.
Foodstuffs, which owns Pak'nSave, have been contacted for comment.
