He said the iwi had known about the new application since December 18, so it had plenty of time to put it on the agenda and provide committee members with relevant information.
"Unfortunately, we heard nothing until it was raised on the day at the meeting. This was the reason for not accepting the iwi's recommendation."
That response is offensive, and unsupportive to iwi and to others who oppose the mining, Nui said.
The council committee can't ask for council support again until after submissions close. Its next meeting is on March 13 and Nui hopes the council will reconsider.
Dunlop said Nui's criticism was unwarranted, and the council naturally has a real interest in ensuring any project does not negatively affect the environment or the district.
TTR also has a mining exploration permit for a 63,000ha area inshore from its proposed iron-sand mine. That permit expires in December 2021.
