Discussions began on Wednesday on what changes to make to a 30-year growth blueprint for Auckland following the close of public feedback on the draft.
The Auckland Council has faced criticism in some suburbs for the scale of intensification and high-rise proposed.
Deputy mayor Penny Hulse said there would be a month of discussion behind closed doors, before councillors debate any changes in public.
She said it is not yet clear whether the draft plan can be finalised by the target of the end of September.
Ms Hulse said the council is conscious that a proposed housing accord with the Government can't come into effect until the Unitary Plan is finalised.
