Auckland Mayor Len Brown is promising to involve all Aucklanders in a study on the future of Ports of Auckland and the wider impact on the city.
A majority of councillors voted yesterday to make further reclamation of the Waitemata Harbour for port business a "non-complying" activity in the draft Unitary Plan pending the study.
The rule puts the brakes on the port company's latest plans to expand up to 179m into the harbour while the council, as 100 per cent owner of the port, decides how the port fits into the city landscape.
The port company did not respond to the Weekend Herald, but has previously said it was confident the study would vindicate its expansionary plans as the "cheapest, least environmentally damaging option and deliver the best economic outcome".
Mr Brown told yesterday's Auckland Plan committee meeting considering planning rules for the port that the study was a holding measure to look at the pros and cons.
