What you need to know

To help protect our environment:

  • You must not release any goldfish from containment within the Auckland region.

Benthic habitat, lakes, streams, ponds, creeks, slow-moving waterbodies.

Eats aquatic plants, algae, insects, crustaceans, small fish and fish eggs, competes with native fish. May contribute to poor water clarity and algal blooms by uprooting plants, re-suspending sediments and eating zooplankton.


If you have gold fish as pets or in an outdoor pond, make sure they’re securely contained so they don’t get washed away into other waterbodies in a flood. If you are no longer able to look after your pet fish, find someone who is prepared to give it a lifetime home, or return it to a pet shop for rehoming. Never release pet fish into waterways. Check equipment and vessels for freshwater pests, clean everything that has been in contact with the water and dry everything thoroughly.
