However, under the Hauraki Gulf Marine Park Act, if Defence stops using the site, it would be classified as a recreation reserve and included in the marine park.
The tribe does not want the land if it becomes classed as a recreation reserve, because it is offered as commercial redress in their claim.
The Government proposes taking the land out of the marine park act's provisions to let the deal go through.
Describing the land as "grandstand coastal reserve", Devonport-Takapuna Local Board chairman Chris Darby said the board urged people to express support in principle for the wider settlement claims bill.
However, the board opposed the inclusion of the 3.2ha of coastal land because it was 60 per cent open space and part of the reserves network of a future Auckland.
He said the land was flat and included historic buildings, a gymnasium and other buildings which would give valuable recreational, cultural and educational use.
The board hoped people would come to hear the minister and also make submissions to Parliament's Maori Affairs select committee by April 18.
Kaipataki Local Board member and a former MP, Grant Gillon, said the 3.2ha was part of Narrow Neck land brought under the marine park after a long campaign and should not be converted to private ownership.
Mr Darby and Tamaki Reserve Protection Trust chairman Michael Pritchard complained to the Hauraki Gulf Marine Park Forum on Monday there was no public consultation.
Forum member and Auckland Council member Mike Lee said he was concerned about the possible precedent this sort of legislation change created for the marine park and felt the proposed legislation should at least be investigated by the council in the interests of all Aucklanders.
However, Mr Lee's recommendation was discussed briefly and was lost 7 votes to 10.
Forum member Wyn Hoadley's request for extending the deadline for submissions on the treaty deed of settlement was also lost.
The forum knew about the proposed treaty deal in April last year but was told to keep it quiet.
Department of Conservation representative on the forum, Auckland Conservator Sean Goddard, said the removal of the 3.2ha portion from the marine park would not affect public access to the coast.
