Harrier hounds may soon be helping to protect New Zealand's border from pests and diseases, the Ministry for Primary Industries says.
The Ministry for Primary Industries (MPI) said it was currently trialing two harriers to see whether the breed could "upsize" detector dogs already in place.
The ministry currently uses beagles and labradors as biosecurity detector dogs, and runs a beagle breeding-programme.
The two harrier dogs, Morley and Muse, were described as "super-sized beagles".
Brett Hickman, MPI Detection Technology Manager said harriers were like beagles in appearance, only taller, and described them as "beagles on steroids".
