Mr Brown did not return calls and his chief spin doctor, Dan Lambert, said he was not available to talk to the Herald.
Other politicians were happy to vent their anger at the process, including Mike Lee, who said politicians should not be making decisions at secret workshops before they had seen feedback on the draft Unitary Plan. "We need to take the time to treat the submissions with respect otherwise it's a hollow exercise."
North Shore councillor George Wood said local boards were demanding to see submissions from their local areas but the council was dragging its heels.
Orakei Local Board chairwoman Desley Simpson said the board wanted access to submissions by suburb, not just brief summaries "that don't give us a snapshot of how our communities have voiced their concerns".
Secrecy has been a feature of the Unitary Plan. The council has also set up a political working party which discusses a lot of the detail behind closed doors before making recommendations to the Auckland Plan committee where issues are discussed in public. Records show the committee normally rubber-stamps the work of the political working party.
Behind closed doors
*Political workshops - discuss much of the plan behind closed doors.
*Political working party - politicians who draw up recommendations behind closed doors.
*Auckland Plan committee - council committee that approves recommendations in open.
*Mayor Len Brown and chief executive Doug McKay - hiding secret documents of political working party.
