It was originally billed as a competition for "amateur chefs" but TV3 says it has no issue with a professional chef taking part in Come Dine With Me.
Laurel Watson, who features on the series this week, worked as a professional chef on TV One's Good Morning for more than ten years. She also edited the magazine Essentially Food and is described online by This and That magazine as a "celebrity chef".
While she was open about her cupcake business on the show, there has been no mention of her extensive culinary experience.
Prior to starting her business Petal Cupcakes in Newmarket, Watson was the in-house chef for Good Morning from 1997 to 2009.
Another notable name, Grayson Coutts, was among contestants this week. The son of Russell Coutts, he also was the third place winner of New Zealand's Hottest Home Baker.
