Check, Clean, Dry to protect our waterways

Northland's lakes and rivers are home to many native birds, fish, invertebrates and a wide range of aquatic and wetland plants. They are also highly valued by Northlanders and visitors as a place to swim, spend time with whānau, gather kai and have fun on the water.

Many of our native species are under threat or vulnerable due to freshwater pests such as catfish, hornwort or oxygen weed. These pests can also prevent us from accessing and enjoying our waters.

Freshwater pests are already established in some of Northland’s lakes, rivers and streams and so the key is to prevent the spread.

If you are moving between waterways you can help to reduce the spread of freshwater pests by using the 'Check, Clean, Dry' (CCD) method:

  • CHECK equipment and remove any fragments
  • CLEAN all equipment that had been in contact with the water
  • DRY equipment thoroughly and then wait for at least 48 hours

Collect your FREE CCD pack

The first step to helping to protect our gems like the Kai Iwi Lakes – is super easy.

Just collect your FREE CCD pack from anyone of our regional council offices.

This pack will equip you with the basic advice and tools required to CCD.

Check your gear

Checking your gear for any bits and pieces of plants, fish eggs or even snails that might’ve hitched a ride, is the very least we can do to help protect our gems.

Check any gear that has been in contact with the water including boats, jet skis, kayaks, lifejackets, ropes and paddles.

Remove any fragments and dispose of it in the rubbish.

Clean your gear

Sometimes a lake or river is already infected with a pest but isn’t visible yet. So, without us knowing, we’re already spreading the organism.

This is why we then need to CLEAN our gear after we’ve checked it for any pests.
