Live Australian freshwater crayfish are among the contraband sniffed out by Biosecurity at Auckland Airport in the past three months.
The number of air passengers screened in the first quarter of this year's up well over 1000 percent on the same time last year.
That equates to almost 1.4 million people being screened, whether that's questioned by an officer.
Mike Inglis, Biosecurity New Zealand's northern regional commissioner, reckons they've got enough staff to enough to manage the huge jump in demand.
