Hitchhiker pest risk assessments

Last updated: 10 September 2021


How hitchhiker pest risk assessments are reflected in the app

Every vessel is given a risk rating, which is a combined output of our risk assessments for AGM (Asian gypsy moth 1 ) and BMSB (brown marmorated stink bug 2 ).

The risk assessments compare a vessel’s travel history with the AGM and BMSB management measures as defined by the Craft Risk Management Standard: Vessels 3 (CRMS: Vessels) and the Import Health Standard: Vehicles, Machinery and Parts 4 (IHS: VMP) in order to identify possible contamination. Starboard evaluates risk based on vessel pathways rather than freight.

The colour of the vessel on the map represents this risk of hitchhiker pest (AGM and/or BMSB) contamination, as determined by the occurrence of port visits in an AGM and/or BMSB risk country during the risk period.

AGM The vessel has visited an AGM risk area during the relevant risk period within the last 12 months
BMSB The vessel is a cargo vessel and has visited a BMSB risk country during the risk period
AGM, BMSB The vessel has visited an AGM risk area during the relevant risk period within the last 12 months
and
The vessel is a cargo vessel and has visited a BMSB risk country during the risk period
No risk The vessel did not visit an AGM risk area during the relevant risk period, and has no AIS data gaps of >12 hours during that time
and
The vessel is a cargo vessel and did not visit a BMSB risk country during the risk period, and has no AIS data gaps of >12 hours during that time
Unknown risk The vessel did not visit an AGM risk area during the relevant risk period, but has at least one AIS data gap of >12 hours during that time, when it could have visited a risk area
and/or
The vessel is a cargo vessel and did not visit a BMSB risk country during the risk period, but has at least one AIS data gap of >12 hours during that time, when it could have loaded risk goods from a risk country

Hitchhiker pest information is updated daily at approximately 4 pm NZST.


How our AGM risk assessment works

Starboard’s AGM risk assessment that determines the risk of contamination of vessels closely follows the AGM management measures outlined in the CRMS: Vessels (2018). These measures apply to vessels arriving in New Zealand that have visited a risk area during the last 12 months, with that visit having taken place during a risk period for the area in question.

Starboard considers all vessels globally and searches their track history over the past twelve months. Any vessel that has visited at least one risk area during its respective risk period has a rating of ‘Risk’ for AGM.

Note that the ‘Risk’ classification will stay with the vessel even after a visit to a NZ port. Therefore, a vessel could be classified as at ‘Risk’ on a revisit to New Zealand, even if it had not visited an AGM risk port during its respective risk period since its last visit to New Zealand.

AGM risk areas and periods are shown in Table 1.

Japan – far southern Prefecture of Okinawa 25 May to 30 June

How our BMSB risk assessment works

Starboard’s BMSB risk assessment that determines the risk of BMSB contamination of vessels closely follows the BMSB management measures outlined in the IHS: VMP.

As outlined in the standard, the BMSB risk season begins on 1 September. The measures apply to target vehicles, machinery, and parts (risk goods) exported from their country of origin on or after this date, and which will arrive in New Zealand before or on 30 April.

The BMSB management measures apply to risk goods originating from or passing through BMSB risk countries listed in Schedule 3 of the IHS: VMP. These 37 countries are shown in Table 2.

Table 2: Schedule 3 risk countries

  • Albania
  • Andorra
  • Armenia
  • Austria
  • Azerbaijan
  • Belgium
  • Bosnia and Herzegovina
  • Bulgaria
  • Canada
  • Croatia
  • Czechia
  • France
  • Georgia
  • Germany
  • Greece
  • Hungary
  • Italy
  • Japan
  • Kazakhstan
  • Kosovo
  • Liechtenstein
  • Luxemburg
  • Moldova
  • Montenegro
  • Netherlands

  • Slovenia
  • Spain
  • Switzerland
  • Turkey
  • Ukraine
  • USA (excludes Alaska and Hawaii)

While the BMSB management measures in the IHS: VMP apply to the cargo, our assessment evaluates risk at the vessel level. As a result of Starboard taking on this macro view, some criteria used to determine BMSB risk differ between the management standard and the Starboard risk assessment. These differences are shown in Table 3.

Table 3: Differences between management standard and Starboard risk assessment

Criteria IHS: VMP Schedule 3 BMSB Management Starboard risk model Further details
Goods type Vehicles, machinery, parts, and new tyres Any All cargo vessels, regardless of goods on board, are included in the risk analysis. All other vessel types are set to ‘no BMSB risk’.

See IHS: VMP Schedule 3 (1).

Goods origin Any risk country Any risk country with export pathways via a risk country. For risk countries without maritime ports, the maritime export pathways are generally still via high risk neighbouring ports, so anticipated deviations are minimal. The possible exception would be goods from Slovakia or Czechia exported via Poland, which would not be flagged for BMSB risk.

Additionally, any goods originating from a risk country but transhipped via a non-risk country, and subsequently loaded onto a vessel with no BMSB risk prior to arrival in NZ, would be missed.

See IHS: VMP Schedule 3 (1a).

Risk country 37 countries (see Table 2) 37 countries (see Table 2) See IHS: VMP Schedule 3 (1a).
Export / load date On or after 1 September On or after 1 September See IHS: VMP Schedule 3 (1a,b).
Duration of goods in transit or storage in a risk country before being loaded in that country > 5 days Any duration For cargo originating outside a risk country, but loaded from a risk country after less than 5 days in storage/transit, our model will still flag the vessel for BMSB risk, as it may have loaded other goods originating directly from the risk country.

See IHS: VMP Schedule 3 (1b).

Arrival date in NZ From 1 September to 30 April From 1 September to 30 April See IHS: VMP Schedule 3 (1c).

Classifications from the Starboard risk assessment are similar, but slightly more cautious than the IHS: VMP management standard. This is a consequence of analysing vessel movements rather than cargo manifests. The following example pathways illustrate this difference.

Pathways which could result in inaccurately classifying a vessel as ‘Risk’ for BMSB in Starboard:

  • Vessels transporting non-risk goods (only) from a risk country;
  • Vessels transporting risk goods that spent less than 5 days in a risk country prior to being loaded;
  • Vessels that transported risk goods from a risk country during the risk season, but subsequently unloaded these goods prior to arrival in NZ; and
  • Vessels arriving in NZ with risk goods on board, but only non-risk goods are unloaded.

Pathways which could result in incorrectly classifying a vessel as ‘No risk’ for BMSB in Starboard:

  • Risk goods originating from a risk country, but loaded onto a vessel at a non-risk port (if the vessel has visited any risk countries en route to New Zealand, it will be correctly flagged as having BMSB risk); and
  • Risk goods originating from a risk country, but transshipped via a non-risk country, and subsequently loaded onto a vessel with no BMSB risk prior to arrival.

Note that conditions which could exempt individual containers or freight from BMSB management measures do not exempt its host vessel from risk assessment in Starboard. For example, BMSB management does not apply if risk goods are loaded into a fully enclosed container which is sealed before 1 September and then exported before 1 October of the same year.

Furthermore, BMSB management does not apply to breakbulk transshipped through a risk country if the duration in the risk country is less than 120 hours and if the goods are segregated from sources of possible BMSB contamination. Likewise, for risk goods in a fully enclosed container if the contents remain in the unopened container while in the risk country.

In each of these examples, we do not exempt vessels from risk assessment in Starboard, as they may also have loaded other goods which do not meet these conditions at the same time.
