Bunnings will have to defend its “lowest price” claims when it appears in court next month.

The retailer faces 45 charges brought by the Commerce Commission under the Fair Trading Act. After investigating Bunnings between July 2014 and February 2016, the commission alleges the company’s advertising misled consumers by giving the impression its goods were sold at the lowest price when they weren’t.

The store uses the slogan “lowest prices are just the beginning” in its advertising.

The matter will be called on March 7.
