We have made a concerted effort to put together an exciting programme on “protecting our crops and native flora”, with excellent keynote speakers, offered papers and posters. Our eight themes are designed to cover every aspect of plant pathology, and to include talks and posters from nematologists, mycologists, bacteriologists and virologists so that we can learn from progress made in each other’s sub-disciplines. We thank the members of our society who are organizing eight workshops, including two field studies, to further facilitate interaction and learning. We trust you enjoy the City of Sails, Auckland, and get a chance to experience this first hand after the conference on the numerous cruises, charter yachts and ferries that criss-cross the Waitemata Harbour, as well as other sources of scenic beauty in Auckland and throughout New Zealand.
