A supermarket action group's questioning the Commerce Commission's decision making

The Commission's decided not to investigate Sanitarium's move to pause the Warehouse's Weet-Bix supply - finding no evidence of anti-competitiveness.

Sanitarium paused supply after the Warehouse began selling the cereal more cheaply than major supermarkets.

Grocery Action Group's Ernie Newman says the Warehouse has had one issue after another, since it began selling groceries.

He says people knew it wasn't fair play, but it seems the Commerce Commission doesn't - and it has fumbled this one.
