The proposed changes are subject to approval from Northland DHB.
Webber said all practices would be funded using the same funding formula, ensuring 100 per cent financial transparency.
"General practices would still be able to access their Mahitahi Hauora relationship partner for all their everyday needs, we would still operate as a PHE in supporting them to meet all their commitments."
Webber said the changes, in turn, would mean an end to Mahitahi Hauora's complex contract arrangements and their obligations.
General practices would receive all funding through a single contract with the PHE, he said, with accountabilities clearly laid out in a service agreement.
Webber said Te Tai Tokerau was a complex landscape of primary health providers operating in different spaces and with many varying and sometimes competing priorities.
"Under our proposed new approach, the core focus of Mahitahi Hauora would be to become relationship partners to the system. We would offer services to general practices, Māori health providers, community organisations and groups, NGOs, whānau, iwi, and other movers in community healthcare, and we would share our skills, expertise and knowledge of the Northland health system.
"By taking this new approach we can more effectively support community aspirations for achieving equity and addressing disparity in a way that is driven by whānau and communities themselves and what matters to them."
NDHB chief executive Dr Nick Chamberlain said NDHB has agreed to further discussions with Mahitahi Hauora on its intentions but has not agreed to any of these changes as required under its funding agreement.
"It is unlikely NDHB would agree to any pass-through of funding without clear service delivery improvements," he said.
