Halyomorpha halys, or brown marmorated stink bug, is a species of stink bug native to China, Japan, Korea and Taiwan which has recently become invasive in the USA. It infests both cultivated and wild hosts and feeding damage results in economic loss and disruption of integrated pest management programmes. Additionally H. halys is a significant public nuisance in its aggregation phase. Halyomorpha halys is not present in New Zealand; however, there have been recent border and post-border interceptions. This analysis examined the biosecurity risk posed by H. halys entering New Zealand. The most likely pathways of entry were assessed. Also assessed were the economic, social and environmental impacts of establishment.
