Why the PM is supporting removal (?) of s59

I had the opportunity to talk to the PM this morning on NewstalkZB and put a two-part question to her; Why do you believe removal of section 59 will stop child abuse and why are you not allowing your party to exercise a conscience vote on this matter?

This is her verbatim answer;

Firstly, I have never said it would stop child abuse. Secondly, It isn't removal. It is an amendment to section 59. The plain fact is that smacking or hitting or assaulting a child now is a crime under the Crimes Act. Some people are prosecuted. They are the people who have been seen to have seriously beaten a child. Because the law says that there is a defence of reasonable force people who thrash and hit children are escaping conviction and that's not right. Now, we are right down the bottom of western countries with a terrible record of threats to child safety, child death and injury and we have to do something about that and sending a signal that really, there are other forms of discipline available is very important. I no more think that the parent who lightly smacks a child will be dragged into court than I would fly to the moon. I just don't believe that. But what I believe is that section 59, with that legal defence which can be mounted needs to go because it is enabling people who viciously assault children to get off.

She omitted to answer the second part. Perhaps because she gave me an answer in two parts she thought she had.
