"These kids have done so much to try and save Marineland and the animals and they're not giving up. Good on them," she said, before setting off with her grand-daughters to take part in the beach clean-up in the immediate area of Marineland.
Among the volunteers were a group of people visiting from Auckland who stopped to see what was going on and joined in.
The council is planning to revamp the site into an upgraded skatebowl and scootering adventure centre, effectively a relocation of the present Sk8 Zone.
The remaining animals would be relocated to marine zoos and parks in Australia.
Leader of the Marineland Rangers, Brianna Otto, said the group would continue to stage beach clean-up days.
They collected a dozen buckets and bags of rubbish, mainly cans, bottles, broken glass and plastic items.
"We keep hoping and praying that the council has a change of heart," she said. "If they saw how many people stop and get excited looking through the fence at the animals they might just realise the potential of the place."
