A new hi-tech baggage scanner at Auckland Airport will provide another crucial layer of protection against invasive
pests and diseases, says Biosecurity New Zealand.
The computer tomography (CT) scanner made its first detection earlier this month – two bananas in a small carry-on bag
arriving with a New Zealand family from Dubai.
Biosecurity New Zealand has been trialling the technology with selected flights since late October. Arriving passengers
have their hand baggage scanned before they collect checked-in items from the airport carousels.
“We’re deliberately targeting baggage that travellers carry off the plane. It’s where we’re most likely to find food
that could host fruit fly and other pests,” says Brett Hickman, Border Technology Manager, Biosecurity New Zealand.
Biosecurity is crucially important to New Zealand, says Mr Hickman, as an unwanted pest or disease could devastate New
Zealand’s primary sector economy or its natural environment.
He says the new scanner provides three-dimensional images that are much clearer than traditional x-ray images.
“The 3D images make it easier to pinpoint items of biosecurity concern.”
Mr Hickman says the technology screens baggage faster than x-ray. It also has potential to automatically detect risk
items arriving with international passengers and mail.
“We’re working closely with Australia authorities and the manufacturer to develop software that will make this a
reality.
“We have already started developing algorithms that can find fruit, meat and seafood, and prospects are looking good for
detecting seeds.”
Biosecurity New Zealand now has two CT scanners at Auckland Airport. Officers have been trialling a larger unit since
late 2018 to scan suitcases and other checked-in baggage.
“We plan to use the technology to screen baggage before arriving travellers pick up their belongings from the airline –
similar to how security screening operates at many international airports,” says Mr Hickman.
“The screening information will be electronically directed to officers, putting them in a better position to evaluate
risk when they interact with travellers”.
