Labour leader David Cunliffe yesterday welcomed a move by the Kohanga Reo National Trust to revamp its governance structure as a step towards regaining public confidence.
But he said it was no substitute "for credible responses to critical questions that should have been answered months ago".
He pointed the finger of blame at Education Minister Hekia Parata for not insisting on a full review of the trust's subsidiary, Te Pataka Ohanga, when allegations of mis-spending came to light last year and called on her to resign.
Ms Parata said she welcomed the trust's acknowledgement it needed to change its organisation and clean up the affairs of Te Pataka Ohanga.
