James Kuperus: Onions NZ CEO says British supermarkets selling brown onions cheaply are selling at a loss - Heather du Plessis-Allan Drive

Questions have been raised over how British retailers can get away with selling New Zealand-grown onions cheaper.

Social media highlighted that New Zealand brown onions were selling for 95p ($1.69 NZD) a kilo at Tesco.

In comparison, those same onions went for $2.99 a kilo at Countdown and $2.39 a kilo at Pak’n Save.

Onions NZ CEO James Kuperus says that Tesco has to price-match Aldi and the rival retailer wouldn't have gotten their product from New Zealand.

"I suspect the Aldi product isn't from New Zealand, so that's where the complications are possibly coming from."
