On the Vote No website, Barnett fronts a video saying, "Kiwi parents know the difference between a light smack and child abuse."So while the "No Vote" headline celebrity expresses confidence in Kiwi families, the "Yes Vote" counterpart - in her own words - confesses to violent urges!
But at the Auckland Town Hall yesterday, Malcolm filmed a statement of support for the "anti-smacking" law with former TV One newsreader Judy Bailey, Kidzone host Kayne Peters, author Brian Edwards and others.
"I'm supporting this because I believe that any type of violence towards children is completely unacceptable," she said.
Malcolm has never smacked her sons, now aged 5 and 3.
"I have wanted to smack them - I've felt the urge," she admitted.
Who do you think is going to bring in more votes?
