A seabed mining protest planned for Patea on Sunday will be a peaceful chain of people holding hands along the coast, organiser Bianca Mitchell says.
"It will be a chance for everybody to stand together, just for a moment."
The protest is against the Environmental Protection Authority's decision to allow iron-sand mining 22km off the Patea coast. That decision can still be appealed.
People are asked to gather at the Patea Beach surf shelter at 1pm, where two teenagers will say a few words and organise the line-up.
Mrs Mitchell, a teacher at Patea Area School, said the event was "a community thing" and a lot of people are really upset about the proposed mining.
