Auckland Council's partners in a study on upper North Island ports are up for more work to get the best out of the ports of Auckland, Tauranga and Northland.
Whangarei District Council and Northland Regional Council support the case for the next stage of the PricewaterhouseCoopers (PwC) study, which last November found that the ports will experience strong growth but Auckland will face capacity constraints ahead of Tauranga and Northland.
Northland Regional Council growth infrastructure manager Vaughan Cooper and Whangarei District Council group manager for district living Paul Dell say the PwC report on freight needs for the Upper North Island Strategic Alliance (UNISA) does not answer a crucial question: What is the best investment for NZ Inc?
They say Northport's location at Marsden Point, with ample land and deep water access, means it is not subject to the external pressures on waterfront space faced by Auckland and Tauranga.
The two Northland councils want more detailed investigation into the different options and potential costs, including understanding the supply chain costs for a customer in Auckland using Northport rather than Ports of Auckland.
