Auckland Council will look at shrinking the area for Ports of Auckland's future growth after an independent study found the need for reclaiming more of Waitemata Harbour is not as substantial as claimed.
The PwC technical study of freight demands at three North Island ports and how to meet them was presented to councillors yesterday.
It said Auckland's council-owned ports company had significant potential for squeezing in more containers on its site and development was under way for a container berth and a 3.6ha reclamation.
It noted that bulk freight berths was a more pressing issue and would be worsened by the potential loss of Marsden and Captain Cook Wharves. The port would need more berth and storage space through reclamation inside 30 years to cater for projected growth of 2.2 per cent to 3 per cent a year in throughput.
However, the need for additional reclamations was not as substantial as the preferred options in the 2008 Ports of Auckland Development Plan, which envisaged an extra 18ha of harbour would be needed.
