Protecting Aotearoa
New Zealand's Waterways
Ko te wai te ora ngā mea kātoa
Water is the life giver of all things
Operation Clean Sweep (OCS) is managed locally by Plastics New Zealand. OCS is an international, industry-led programme helping companies eliminate plastic pellet, flake, and powder loss to the environment.
Here in New Zealand, plastics-handling sites must pass an audit to gain OCS certification. This helps ensure that the correct measures are in place to prevent raw plastics from polluting our precious awa (rivers) and moana (oceans).
No one wants to cause pollution, but accidents happen. Without the proper equipment and procedures in place, spills are easily blown or washed into stormwater drains. These drains connect to natural water systems, and ultimately the moana (ocean).
From Site, to Sea...

Watch to understand how spilled resin flows from site to sea.
All players across the plastics supply chain have a role to play in preventing pollution of our waterways.
