Abstract
Avian paramyxoviruses (PMV) and influenza viruses have been readily isolated from free-living birds throughout the worldCitation(1) Citation(2) and, in New Zealand, both these viruses have been isolated from wild waterfowls, particularly ducksCitation(3) Citation(4). It is widely known that free-living birds could harbour PMV and influenza viruses and could act as natural reservoirs of these viruses. They have occasionally caused Newcastle disease (PMV-1) and influenza outbreaks in commercial poultry farms throughout the worldCitation(5) Citation(6) Citation(7) Citation(8). However, similar outbreaks have not been reported from New Zealand.
