Summary

Wastewater-based surveillance (WBS) is a useful tool for non-invasively screening arrivals at the New Zealand border en masse for a range of different biological and non-biological contaminants. A previous report prepared for the Ministry of Health assessed the logistics of conducting WBS at New Zealand’s international airports, including sampling directly from inbound international aircraft and from airport wastewater networks. This current report extends this assessment by evaluating a wide range of different contaminants for their suitability for WBS.
