Countdown supermarkets across the North Island have pulled Homebrand milk from the shelves after customers complained it smelt and tasted like chemicals.

SupermarketNewsNZ has reported on social media that Countdown's voluntarily removed its Homebrand 2- and 3-litre lite blue milk bottles with a February 11th expiry date.

The supplier of milk to Homebrand hasn't been named.

It's understood there's no food safety risk to consumers.

Customers who bought a bottle are being urged to return it for a full refund or replacement.
