Marine biotoxin alerts.

Shellfish and seawater samples around New Zealand are tested each week to ensure they are not contaminated with biotoxin from blooms of algae. Public warnings are issued when shellfish are not safe to eat. This page contains information relating to the non-commercial (recreational and traditional) taking of shellfish only.

This page is updated as soon as new information comes to hand. All the warnings on this page are current and remain in force.
