The council's lawyer, Alan Galbraith, QC, said the resource consents were not determined by public opinion.
Council staff, Mr Galbraith said, did not consider the applications by Ports of Auckland met the threshold of being "significant and contentious" and allocated them to duty commissioners for a decision.
He said this was an orthodox and reasonable application of council policy, taking into account they were for a controlled activity, which could not be declined.
Jim Farmer QC, for Ports of Auckland, said the judicial review of the consent decisions was not the right forum to address broader planning, environmental, social and political issues claimed by Urban Auckland.
Mr Farmer said construction of the wharf extensions was subject to controlled activity status in the coastal plan which meant they were approved without public notification unless there were special circumstances, which there are not, he said. The port company's submission talks about real and significant costs and capacity constraints if the extensions cannot be built or are delayed. The costs of any delays are redacted from the public copy of the submission, but the company suggests shipping companies going to other ports could wipe $86 million off the value of the company.
