Food delivery service My Food Bag accidentally sent two ingredients containing animal products to its vegetarian customers this week.
My Food Bag - New Zealand's third largest food business behind the two major supermarket chains - said it regrets the error and moved quickly to fix it.
"My Food Bag was alerted to two incorrect ingredients in the Vegetarian bag delivered yesterday, " My Food Bag's Ryleigh Cornes said in a statement.
"One was a sauce that contained chicken broth and the other a cheese that contained animal rennet.
"The efficient customer service team have re-sourced the product and My Food Bag is replacing the two items overnight," Cornes said.
