A New Zealand company is using drone to help catch poachers in South Africa.

Aeronavics is a Raglan based drone company which has designed a drone to help protect the last of the rhinos left.

Recent studies estimate roughly 18,000 southern white rhino and 5500 black rhino are left in Africa but the numbers are dropping.

Rhino horn is trafficked by poachers into Asian countries where they are believed to have healing powers, or they are simply poached as a status symbol.

Aeronavics director Linda Bulk spoke with Mike Hosking about how to company got involved.
