During routine surveillance by Biosecurity New Zealand in February, specimens of a beetle were collected from an oak tree in Auckland. They have been identified as Xylosandrus crassiusculus (Coleoptera: Curculionidae: Scolytinae), the granulate ambrosia beetle. This is an exotic species that has not been recorded before in New Zealand. The beetle has since been identified in other locations.
