Police say concerns that good parents would be prosecuted under the controversial anti-smacking law have again been proven unsubstantiated.
Police have published their 11th review of the Crimes (Substituted Section 59) Amendment Act 2007 which covers the six-month period from December 2011 to June 2012.
In total, 355 reported child assault attended by police during this period were considered for the review.
It found that of the 12 "smacking events'', none resulted in prosecution, nine warnings were given and three required no further action.
Of the 31 "minor acts of physical discipline'' events, nine resulted in prosecution.
