"The council's top-down 'my way or the highway' approach to growth has killed off the excitement we all should be feeling about Auckland's future," Mr Palino said.
He said the way to fund a second CBD was through local government infrastructure bonds, which would be offered to New Zealanders first. The project would also justify lower, if not waived, development contributions.
Mr Palino's alternative to suburban intensification comes as Auckland councillors gear up to make decisions on the Unitary Plan at a three-day meeting starting on August 28.
Among the contentious issues still to be resolved are plans for small-scale apartment buildings in half of suburban Auckland, which have been toned down after concerns that developers would be able to apply for resource consent for three-storey apartments without any public say.
Building heights, heritage rules, minimum dwelling sizes, development controls and volcanic viewshafts are other meaty issues at what Deputy Mayor Penny Hulse has called the "pointy end" of the process.
Once the Auckland Plan committee wraps up the detail, the Unitary Plan is likely to go to the last council meeting this term on September 5 for ratification.
It will then take between three and four weeks to print and notify the document, leaving little time for Aucklanders to digest it before postal voting closes on October 12.
