Implementation: Effectiveness of sentinel (expatriate) concept is reported directly to MPI and International Plant Sentinel Network (Botanic Gardens Conservation International). Generic learning is shared with other sentinel projects (i.e. B19.3, B19.4). Specific information on target organisms is provided relevant parties (e.g. Zespri/KVH for kiwifruit, BMSB to GIA, BMSB Council, myrtle rust to DOC, TTW) and MPI (Science & Risk – Plants & Pathways (Emerging Risks System), and Biosecurity Intelligence Team).
