Shoppers at an Auckland supermarket lashed out at a vegan protest taking place there on Sunday.

Activists stood in front of the meat section at Countdown St Lukes holding signs demanding shoppers stop eating animals.

Video of the event shows one of the organisers, Anna Rippon, shouting at staff when they asked her if she had permission, explaining it was a peaceful protest for the "victims" of the meat industry.

"The impact of a non-vegan diet is the victims who we don't usually hear from, we're here today to give them a voice," she said later in the video.
