The Commerce Commission has filed proceedings against GIB manufacturer Winstone Wallboards for anti-competitive behaviour.
The watchdog says Winstone's use of rebates after purchases to damage competition led to higher prices for consumers between 2017 and 2022.
The commission says it has filed proceedings under sections 27 and 36 of the Commerce Act in the Auckland High Court against the company, which is a subsidiary of Fletcher Building.
