WELLINGTON, Dec. 18 (Xinhua) -- A sophisticated X-ray technology available to scrutinize bags of international travelers for unwanted pests was unveiled on Tuesday at Auckland Airport.

"Our dynamic biosecurity environment means we must constantly adjust our scrutiny and strengthen our border security as threats emerge," Biosecurity Minister Damien O'Connor said while unveiling the technology.

The million-dollar scanner features three-dimensional imaging, or real-time tomography, that will make it easier for quarantine officers to pinpoint risky items that have been difficult to detect in the past such as dried meat, goods hidden behind laptops and stink bugs, O'Connor said.

Biosecurity New Zealand is also developing software with Australian counterparts that will allow the scanner to automatically recognize risky items such as fruit that could harbor fruit fly, the minister said.

"This is a game changer for biosecurity. It is the most sophisticated piece of X-ray technology we could have in place to support our officers at Auckland Airport and provides another useful tool in our multi-layered biosecurity system, sitting alongside 50 detector dog teams, arrival cards, risk assessment and public awareness campaigns," he said.

The scanner will check bags before passengers pick them up and images will be sent to quarantine ahead of any searches, similar to how security X-ray screening operates at many major international airports, he added.

"Ultimately, we want this technology in place across the passenger, mail and cargo pathways as traveler numbers and trade increases," O'Connor said.

"It's important we all do our bit for biosecurity as we all benefit from a country relatively free of unwanted pests and diseases and we all suffer the consequences of an incursion," he added.
