What's New Zealand doing wrong when it comes to child abuse?

New Zealand has one of the worst records of child abuse in the developed world and the woeful number of cases continue to grow. 

Every year there are more than 150,000 reports of concern relating to children in this country. 

On average one child dies every five weeks as a result of violence in New Zealand, with children under 12 months old making up the majority. 

In 2015, there were 14 victims of homicide aged under 14. Eleven of those victims were under the age of 5.

And children under the age of 18 make up 20 percent of all violent deaths in New Zealand.

The cost of child abuse in New Zealand is estimated to be around 3 percent of GDP - approximately $6 billion a year.

And just six days ago, a 39-year-old man was charged with the murder of a Tauranga toddler who died of head injuries last month.

Yesterday, a mother and her partner admit to neglecting their child leading to the four-year-old dying under their care after sustaining the same injuries people suffer in car crashes.

Children's Commissioner Judge Andrew Becroft spoke to The AM Show.
