Understanding where and when a vessel has visited a port can help to assess a vessel’s biosecurity risk. Using the advanced filter for past port visits means you can filter to arriving vessels that have visited ports in potentially high risk areas in the last 7, 30, 90 days, or the last year.

Try it out: See vessels arriving in Aotearoa from a foreign port that have visited high-risk Giant African Snail (GAS) infested countries in the last year.

The past ports filter can help to prioritise vessels arriving for inspection and the vessel list includes the vessel’s arrival (or estimated arrival). Vessel’s can also be tagged from the vessel list to indicate they may be high risk or require an inspection.

When using filters to identify potentially high risk vessels you will only be able to identify known high risk vessels. Those with an unknown risk, where we do not know the vessel’s full travel history because it has at least one AIS data gap of >12 hours, are not assessed.

A vessel’s risk is not reset to low risk on departure from a New Zealand port or anchorage. Even if they have already been inspected they will still appear using the filter set.
