The council approval which allowed demolition of a 130-year-old cottage in Paget St, Freemans Bay, was the catalyst for the panel to press the council to urgently look at initiating a plan change or varying the rules for the demolition or removal of pre-1940 buildings in the Residential 1 and 2 zones and other heritage character areas in Auckland.
In the Paget St case, consultant planner Brooke Dales was given the case at the 11th hour after council planner Jonathan Blackmore supported the view of a conservation architect that the application should be declined.
Mr Dales decided the public would have no say and recommended it be demolished.
The panel chairwoman, councillor Sandra Coney, said planning officers opposed taking urgent action on the grounds any changes should be part of a new unitary plan, which, she said, was about two years away.
At the current rate that was the demolition of another 30 homes, "which is 30 too many for me".
Ms Coney said not all the decisions were wrong, but some were. A good example was Paget St, she said, where the significance of the house to people in the street and a deeper understanding of the history of the property did not emerge until after consent was granted.
Mr Brown issued a statement from China, where he is leading a trade delegation, dismissing immediate action to stem the demolition of homes and give the public a say.
"The unitary plan process will establish the rules that govern development and how we deal with heritage protection. There are legal issues that would hamper immediate action as the last plan change is still before the courts. I'm also wary about distracting from the current process with yet more planning," he said.
But Mr Brown said he was open to suggestions on how to better protect Auckland's heritage and would be discussing the matter with councillors and officers.
Its chief planning officer, Dr Roger Blakeley, defended the council's record on Residential 1 and 2 approvals.
He said that of the 73 applications, six were for partial demolition, 15 homes were of poor structural quality and 31 had been modified, two were retrospective and three were declined by the council but approved by the Environment Court.
