Conducted annually since 2015, the New Zealand Colony Loss Survey is based on the survey of beekeepers developed by the international COLOSS honey bee research association.
Survey topics include the number and nature of over-winter colony losses, queen health and performance, indicators of diseases and parasites, treatment of Varroa, supplemental feeding, and colony management. Because the challenges facing New Zealand beekeepers differ from those facing beekeepers in the northern hemisphere, the survey also includes questions that are specific to the New Zealand context, e.g. apiary crowding, predation by wasps, and nectar flow from native trees.
