MARINE BIOSECURITY Porthole

Sources of data

The Marine Biosecurity Porthole contains the most complete source of information on the national distribution of non-native marine species in New Zealand.

Distribution records in the portal come from four principal sources:

  • Port Biological Baseline Surveys
  • National Marine High Risk Site Surveillance
  • Marine Invasive Taxonomic Service
  • Other verified observations of non-native marine species

Find out more about each of these sources of data in the pages below or download the following publication.
