A Maori affairs select committee report on pending Treaty legislation says some opponents of Devonport defence land passing into the ownership of an Auckland hapu are motivated by "mistrust".
But Devonport-Takapuna Local Board chairman Chris Darby, who has challenged 3.2ha of naval land at Narrow Neck being used as commercial redress under Ngati Whatua o Orakei's settlement terms, warns the issue could haunt future generations.
The committee recommends few changes to the bill, which went for public consultation this year against a backdrop of anger about the land's future - it is part of the Hauraki Gulf Marine Park, but will be taken out to settle the tribe's claim.
Its report also touched on feelings towards the tribe: "We were, however, disheartened by those submitters who opposed the bill largely on grounds that stem from mistrust and misunderstanding."
It encouraged Devonport residents who had reservations to "work towards a positive relationship" with the hapu, which is based across the harbour.
