New Zealand First Winston Peters is blaming all Maori for the killing of the Kahui twins.
Police have decided not to pursue any further charges over the deaths of the three-month-olds.
Coroner Garry Evans said their injuries were inflicted while they were in the care of their father Chris, but he was acquitted on murder charges.
His lawyer Lorraine Smith says Mr Kahui can now get on with his life, saying he'll never get over his twins' deaths.
Mr Peters says the whole of Maoridom should be bowing its head in shame.
"That's a serious blight on Maoridom and we have to own up to it. The cone of silence around it led to a lot of uncertainty as to what the evidential facts were and Maoridom's got to take initiative of that and say 'this cannot be allowed to go on in the future'."
A shocking rate of child abuse is not unique to Maori, but there is no argument that Maori are more highly represented in abuse statistics.
And Winston Peters is quite right; the solution to stopping child abuse by Maori lies with Maori; we commend him for saying what others have thought but have feared to verbalise.
The Kahui case was appalling; a whole whanau took advantage of the Police allowing cultural sensitivity to be predominate in the days immediately after Chris and Cru Kahui died. Now we find that no-one will ever be held criminally responsible for the murder and abuse of the defenceless twins.
The overwhelming majority of Maori do not beat, abuse and kill their children, and they are the ones who must condemn those who do the loudest. If he really wants to build a legacy for Maori, King Tuheitia and his acolytes should take their focus away from hui on matters about how to build their empires and challenge the attitudes that made children like Nia Glassie and the Kahui twins playthings and punching bags rather than the treasured taonga the every tamariki deserves to be.
A concerted effort by Maoridom's leaders is required. Perhaps it is time for Winston Peters to take on that role and use the years he has left in his political life and his high public profile to champion the rights of Maori children, and to erase the "serious blight on Maoridom" to which he referred yesterday.
