Programme Information

The Marine High Risk Site Surveillance programme

Undertakes 6-monthly surveys for marine pests in 11 of New Zealand's busiest ports and marinas of first entry for international vessels. It has three objectives:

  •  The primary objective is to detect incursions to New Zealand of high risk non-indigenous organisms listed on the Unwanted Organisms Register that are not known to be present in New Zealand.

Information about these organisms and identification guides can be found on the Primary Target Species page.

  • The secondary objectives of the programme are:

— to detect incursions to New Zealand of non-indigenous or cryptogenic organisms that are not listed on the Unwanted Organisms Register and

— to detect range extensions by established non-indigenous or cryptogenic organisms that exhibit characteristics of pests. You can find out more about some of these established marine pests by clicking on this link.


High Risk Sites

As the name suggests, the national Marine High Risk Site surveillance is undertaken in some of New Zealand's busiest ports and marinas of first entry for international vessels. These are the sites where incursions by marine species not currently in New Zealand are most likely to occur. Eleven harbours are included in the programme. Within each harbour sampling is focused on the habitats and locations where the primary target species are most likely to occur.


 

Survey Methods used in the Marine High Risk Site Surveillance

Survey methods used in the marine high risk site surveillance have been chosen to optimize detection of the primary target species. An important consideration was the efficiency with which samples could be taken in the field since the chances of detection are greatest when a large number of samples can be taken.
