With the referendum on smacking at a go and media reporting rather one sided in favor of the so called YES vote. The Vote NO site gives you the other side of the story. The site is understood to be an initiative of Family First, and appears to be supported by the For the Sake of Our Children Trust, FIANZ, the Pasefika Trust, the Fact and Family Trust, the Sensible Sentencing Trust, Unity for Liberty, Focus on the Family, Cross Power and Family Life NZ.
The FAQ page consists of highly condensed yet to the point information in relation to the issues at hand: is the law working, prevention v correction, did this law help stopping child abuse, smacking and minor acts of physical discipline and more. So for those that want to hear the other side of the story as well I recommend you check the site out.
Also check out The Yes Vote Fail site for a slightly lighter approach, where I found the videos below.
