Ms Chetham said the plan change could help re-establish traditional Maori communities in Northland.
"The provisions allow for that kind of holistic community that [Maori] used to have. That could include marae, kohanga, elderly housing, health-related facilities and even environmental facilities," she said.
Proposed changes to Te Ture Whenua Maori Act would also allow councils to forgive rates arrears on unproductive land, if owners demonstrated a commitment to developing it. Mr Chetham said remaining barriers included a risk of further restrictive rules under Northland Regional Council's recognition of "outstanding natural landscapes" in its regional policy statement.
The main restricting factor to developing Maori land - outside the scope of council - was the difficulty in obtaining loans. Effectively, multiply owned Maori land cannot be valued or sold on the open market, so banks are wary of their lack of security.
The first phase of the plan change became operative in 2011.
New changes meant papakainga developments were allowed, subject to building consent and effluent disposal requirements.
Mr Innes said the new changes would "take the bureaucracy out of the development of [Maori] land".
