More Kiwis are swapping cows' milk for soy and other milk alternatives, new data shows.
Foodstuffs spokeswoman Antoinette Shallue said retail sales of soy milk in New World and Pak'nSave stores grew 3.4 per cent in 2011 and 1.5 per cent last year.
But she said the sales of rice milk and almond milk grew 8.1 per cent in 2012.
Vitasoy general manager Neil Hinton said there had been up to 30 per cent growth in retail sales of soy milk over the past five years.
But he said where growth had really been noticeable was in cafes: "It's almost exponential."
