MPI detection technology manager Brett Hickman said the breed was ideal for the day job.
"Our MPI-bred beagles have proven themselves as excellent biosecurity detector dogs.
"They are ideally suited to working at airports and ports to sniff out food, plants other items that could pose biosecurity risk to New Zealand."
The MPI naming competition - for one female and one male name for the youngsters - finishes on Friday when judges will select the top pick.
