Daisy, an energetic pointer, is among eight new detector dog teams beginning their jobs in Auckland this week as the international travel season kicks off.
The dogs and handlers finished their training last week and have begun their duties.
Outbreaks of fruit fly cases in Australia and the Pacific have the Ministry for Primary Industry concerned and the new dogs and handlers extend the surveillance of arrivals.
Border clearance services director for MPI Steve Gilbert said Daisy the dog was sourced from a Tokoroa dairy farm and is the first pointer trained for biosecurity work in three years.
"She has high-energy and likes to keep busy. These are qualities we look for in a detector dog," Mr Gilbert said.
