On 16 October, councillors and Local Board chairs had a confidential briefing on the latest maps showing historic heritage overlays and the extent of the temporary pre-1944 heritage overlay.
According to the Herald, large areas of the pre-1944 temporary overlay, giving protection from demolition without consent, before the new Unitary Plan rules are in place, have been abandoned.
Some heritage suburbs, have largely kept the heritage overlays, and in some parts, particularly Westmere, they have been added to.
But many central suburbs seem to have patchy and arbitrary protection, and most of Mission Bay, Kohimarama and St Heliers have virtually no protective overlays.
Councillors only get a few days to look at these crucial maps, and will be voting on them in a closed meeting on 21 October.
