Ports of Auckland will start work on wharf extensions in April - the first step in a broader plan which aims to reclaim more of the Waitemata Harbour for port use at a later date.
Yesterday, the Auckland Council voted in favour of more generous rules allowing expansion over the seabed.
Auckland Mayor Len Brown and Deputy Mayor Penny Hulse led a 12-10 secret vote to insert rules in the council's Unitary Plan that will make further reclamation of the harbour for port use easier.
The city leadership quashed an 11th-hour attempt by eight councillors and two Maori Statutory Board members to strengthen the rules and make it harder for the port company to reclaim more of the seabed.
The council will now go into mediation on Monday on zoning rules for the port precinct in the Unitary Plan with the soft line of "discretionary" status, instead of the tougher line of "non-complying" status.
Mr Brown and other councillors rejected a late plea from Warehouse founder and Kiwibank New Zealander of the Year Sir Stephen Tindall to halt reclamation until a full study of the economic, social and environmental effects was complete.
The council voted to start the study "sooner rather than later", but this does not stop the port company beginning its expansion plans.
A ports spokesman said last night work on two large wharf extensions nearly 100 m beyond the end of Bledisloe wharf would start in April. Work is expected to take 18 months.
Ports of Auckland obtained resource consent last December to extend the wharves.
The port company has said this is the first stage of a plan to reclaim 3ha of seabed between the wharf extensions over time.
The company will require a publicly notified resource consent for the reclamation.
Sir Stephen said politicians should use all their powers to stop this kind of "incremental approach".
Urban Auckland representative Julie Stout has produced images showing that the current view from the end of Queens Wharf, which extends to the Hauraki Gulf, would be narrowed to Devonport wharf once the Bledisloe wharf extensions are completed next year.
Mr Brown issued a statement after the vote seeking to downplay the implications of yesterday's decision.
The mayor said he did not expect the port to make any applications for reclamation until after the Unitary Plan became operative, expected to be next year. The ports spokesman confirmed this.
In the meantime, Mr Brown said, the council would undertake the wider study.
Tania Loveridge, of the Heart of the City business group, said it was critical for the council to find a way to put the planned Bledisloe Wharf extensions on hold until the study was completed.
"Our waterfront is too important to make incremental changes."
