This is the second clean-up the council has organised.
As well as the clean-up, they have organised all sorts of activities for kids and families - a beach dig, spot prizes and giveaways, falun dafa, planting in the dunes and a free sausage sizzle.
Department of Conservation community ranger Katy Newton said collaboration was key when it came to such initiatives.
"Then we all have our networks and can spread the search. DoC is really keen to help the Multicultural Council and others to take care of the environment."
The goal of the mission is to keep the ocean waste-free and stop it from moving across the country or the neighbouring Pacific Islands.
"If we can stop that process here, that is good for us," said Newton.
