This week the Herald revealed that a secret briefing of Auckland councillors was presented with four "immediate options" to resolve the public outcry and stand-off between the council and port bosses over the extensions.
The options include allowing the port to proceed with the extensions and the council sticking to its guns for Ports of Auckland to down tools while a year-long port study is done.
But it is understood that councillors are being urged to accept one of two compromise options. The first is to go ahead with the eastern extension and reduce the western extension from about 92m to 40m. The second compromise is to only build the eastern extension and wait for the port study and new planning rules in the Unitary Plan before considering the western extension.
Mr Peters, who was sworn-in as Northland's new MP this week, said Whangarei's Northport, as a natural harbour that does not require dredging like Auckland, was a viable alternative.
"Northport could become a leading port. New Zealand First wants investment in the rail link and sees the development cost as necessary to build a future asset."
