Myrtle rust has been found across the North Island and in upper areas of the South Island.
A surveillance map is available to see the spread of myrtle rust. It contains records of both uninfected host plants as well as the latest known distribution of the disease in New Zealand. The map combines datasets from Biosecurity New Zealand, iNaturalist, the Department of Conservation, Plant and Food Research, and Botanic Gardens.
