One revised option is to reclaim 179m of the harbour to extend Bledisloe Wharf.
Auckland Council will host a battle of the giants tomorrow at the first public test of the Ports of Auckland's new plea for more working space by reclaiming 6.6ha of the Waitemata Harbour.
The council-owned port company will present evidence of its waterfront expansion needs to the council's Auckland Plan committee, which decides policies for the city's new rulebook for 30 years.
Its revised plans will be backed by the Auckland Chamber of Commerce but councillors will also hear objections from Heart of the City and the Westhaven Marina Users Association.
Ports chief executive Tony Gibson acknowledged last year's plan to extend Bledisloe Wharf 283m into the harbour was unacceptable and said the company now proposed two options: 135m or 179m.
