About withering abalone syndrome
This pest comes from the west coast of North America. It attacks the digestive system of abalone. This stops them eating, making them weak and shriveled.
Why this is a problem for New Zealand
This disease could harm our pāua species. It stunts their growth and makes them unappetising.
How it could get here
This disease could hitchhike to New Zealand on used diving gear or aquaculture equipment. Biosecurity New Zealand has strict measures in place to limit the chances of withering abalone syndrome making it through the border. But we need you to play your part – if you are returning to New Zealand with diving gear, make sure it's dry.
How to identify withering abalone syndrome
The main sign that a pāua is infected is a withered 'foot', the part of a pāua that attaches to rocks. Shells remain intact but the body will be shrunken inside.
What to do
If you think you've found an infected pāua:
- take a photo
- collect a sample
- record location and landmarks
- call MPI on 0800 80 99 66 to report your find.
