The Minister responsible for Whanau Ora, Te Ururoa Flavell, says some Government departments are reluctant to get involved in the social policy.
The kaupapa Maori philosophy was for Government services to work collaboratively to help whanau, not just individuals, and for families to take responsibility in helping themselves.
Mr Flavell said Whanau Ora was not only about providers, but also creating ministry partnerships that would ensure funds were used effectively.
He said he had received reports there was a reluctance from some main ministries to provide and assist in a Whanau Ora approach.
Mr Flavell said much of the problem was based around them just not knowing what Whanau Ora is and where they fit in.
They included the Social Development Ministry, health, housing and parts of education, he said.
