Dozens of stink bugs have managed to get into the country in a pair of shoes bought on an American website.
Up to 26 live brown marmorated stink bugs, also known as BMSB, were recently discovered in a box of imported shoes in Oamaru.
The information was released by officials from the Environmental Protection Authority in a select committee yesterday.
"The shoes were purchased from eBay and easily slipped through the border," said National biosecurity spokesman Nathan Guy.
