Radio operator certificates and callsigns

Under national law and international agreements, most operators of radio transmitters in the aeronautical, amateur and maritime services are required to hold a relevant radio operator certificate of competency, and to use a callsign for identification purposes.

Radio transmissions for these services are specified under the corresponding New Zealand general user radio licence (GURL):

  • Aeronautical General User Radio Licence
  • Amateur General User Radio Licence
  • Maritime General User Radio Licence
