Minister for Whanau Ora, Tariana Turia, is still refusing to answer a question about how well her social welfare policy is run.
As Radio New Zealand recently reported, an evaluation shows Whanau Ora funding worth $7.7 million is being handed out without the full results being measured.
The evaluation of the Whanau Integration, Innovation and Engagement Fund for 2011-12 shows there is good evidence the fund is helping families get results.
But it isn't known how many whanau plans have been written or completed.
Mrs Turia refused to talk to reporters last week and she again blocked questions at a media conference on Thursday.
However, at the conference the Whanau Ora Governance Group chairperson, Sir Mason Durie, defended the scheme saying it's heading in the right direction.
Sir Mason says the group is working to put in place better measures of what constitutes success.
New Zealand First also stepped up its attack on the scheme on Thursday.
It said the Minister for Whanau Ora, Tariana Turia, used a speech to paint a pretty picture of the policy - less than a week after a bleak report was released heavily criticising the scheme.
