The third image is also of Wellington beach. The round things are called 'Nurdles' and aren't ocean pollution due to rubbish. They have been spilled by a local company, IML Plastics.
Those "nurdles" are ocean pollution.
They wash in from the ocean, but they from overspill from a local factory. Nothing to do with plastic from the public littering.
