Three quarters of Kiwis say they would pay more for organic, sustainable and ethically produced products.
The latest Colmar Brunton Better Futures Report found New Zealanders were increasingly aware of where and how goods were made.
Of the 13,000 surveyed across New Zealand, 83 per cent said they would stop buying a company's product if it was not being responsible or ethical and 72 per cent said it was important that they worked for a company that was socially and environmentally minded.
Fairtrade and Eco store were seen as leading sustainable brands, and Fairtrade Australia and New Zealand chief executive Molly Harriss Olson said this was reflected in sales.
"In the past year, retail sales value of Fairtrade products across New Zealand and Australia have grown by more than 17 per cent to $379 million," Harriss Olson said.
