Tania Benyon: The Warehouse Chief Product Officer on Sanitarium pulling Weet-Bix products from the retailer - Heather du Plessis-Allan Drive

From Saturday, a Kiwi breakfast staple will be removed from The Warehouse's cereal aisle.

Sanitarium is no longer providing Weet-Bix products to any Warehouse stores, citing 'supply constraints'.

The Warehouse headed straight to the Commerce Commission for a solution- after they discovered they were the only retailer affected.

Chief Product Officer Tania Benyon says it's 'very strange' that Sanitarium chose to cut off supply from The Warehouse instead of reducing output for all cereal retailers.

"From our perspective, it's just very strange that in this time when there's so much intent to open up equitable access to groceries for New Zealanders- we're not able to do that."

Sanitarium issued a statement refusing to comment on their production capacities and stock levels.
