She has drawn up 18 amendments to the rules for the mixed housing suburban zone for a three-day meeting of the Auckland Plan committee from tomorrow to wrap up the Unitary Plan for notification.
"I believe I have support to carry the amendments," said Ms Hartley, a member of Mayor Len Brown's inner circle.
Auckland Council's regional planning manager, Penny Pirrit, said she had only just been made aware of Ms Hartley's proposed amendments and would wait until the Auckland Plan meeting to respond.
Richard Burton, spokesman for the Auckland 2040 movement set up to oppose haphazard development, supported the two subzones when they were proposed last month but said the devil would be in the detail.
Yesterday, Mr Burton said the planners were hijacking the process by trying to set the same unlimited density rules for both subzones.
He said the planners' argument for providing enough capacity for growth was wrong because there was a lot of potential in more intensified zones around town centres.
Development should be focused where it was most appropriate, he said, and the mixed housing suburban zone used as a reservoir for possible future development.
Zoning controversy
Mixed housing zone split in two.
*Three-storey zone near town centres, two-storey in suburban areas.
*Planners want unlimited density rules in both zones.
*Councillor Ann Hartley wants to drop unlimited density in suburban zone.
