Trustees for Tumu Kaituna 14 had previously applied to the Māori Land Court last year to convert more than 55 hectares of their 240ha prime coastal Māori freehold land near Maketū in the Bay of Plenty into general title.
There are 5000 Māori who are shareholders in this land, including all members of the Save Tumu Kaituna campaign group.
Save Tumu Kaituna spokeswoman Renee Kiriona said the council needed to hold off on granting the consent until the matters were settled in court.
"Tauranga City Council have the power, and depending on what decision they make, they can make this even messier for us," she said.
She said the land was not regenerating at the same pace it was being mined and intensifying this would destroy it.
Kiriona said anyone was welcome to join the picketing.
