So awful is this country's record of child abuse that many radical responses have been aired in the past few years.
There was, for example, Social Development Minister Paula Bennett's suggestion that the courts should have the power to ban child maimers from having more children. And there was a coroner's view that all children should be monitored compulsorily until they reach 5, including spot checks of their homes.
That such flawed ideas garnered a measure of support spoke volumes of the widespread despair over the extent of the problem and the failure of policies to address it. Welcome, therefore, is Ms Bennett's long-awaited Children's Action Plan, which, while bound to be controversial, is generally well targeted.
Two aspects of the new regime will be particularly contentious: the wide-ranging Child Harm Prevention Orders aimed at people considered to be a risk to children, and a requirement that parents convicted of killing or abusing their children will have to prove they are safe to care for any subsequent children.
In the first instance, High Court and District Court judges can impose an order for up to 10 years if it is believed "on the balance of probabilities" that someone poses a threat to a child. It will not be necessary for a person to have been convicted of a violent or sexual crime against children. A pattern of behaviour detected, for example, by police intelligence would be sufficient.
