Fonterra has been called out on Facebook for claiming its Mainland feta, made in Denmark, contributes to helping the yellow-eyed penguin in New Zealand.
The company, who supports the Yellow Eyed Penguin Trust with its Mainland cheese products, has been slammed for "green washing" products by making them appear more environmentally friendly than they are.
Dr Mike Joy posted on his Facebook page, alongside a photo of the back of the package of feta: "The idiocy of globalisation and shipping cheese from the other side of the world is very unlikely to be good for yellow eyed penguins."
Joy is a Senior Researcher at Victoria University Wellington's School of Government, and an authority on sustainability and environmental causes.
The package in question tells customers that, by purchasing the product, they are a "Mainland hero", contributing to helping the yellow-eyed penguin.
