Ministry of Primary Industry officials are hoping a new super breed of dog will create the "the perfect sniffing machine" to protect New Zealand's borders.
The ministry has released details of a "world first" breeding programme that aims to create the ideal sniffer dog.
MPI detector beagle Clara gave birth to three male and three female puppies on November 24. The sire was Morley, a harrier hound. Both dogs work for MPI at airports and ports to sniff out food and plant materials that pose biosecurity risk.
"It's the first time anyone in the world has crossed a beagle and a harrier for detection work and we have very high expectations for this super-breed," MPI Detection Technology Manager Brett Hickman said.
"The idea is to combine the height of the harrier with the proven biosecurity qualities of the beagles we have been breeding for nearly 20 years. The result could be the perfect sniffing machine to keep unwanted pests out of New Zealand."
