Licence audits

Who can be audited?

Radio Spectrum Management (RSM) may audit any person, company or organisation transmitting radio waves including:

  • Existing radio or spectrum licence holders 
  • Radio or spectrum licence holders of cancelled licences 
  • Persons operating under a general user licence (Radio or Spectrum licences).
  • The Radio Spectrum Management Compliance Guide for users of the radio spectrum and for suppliers of electrical and radio products is available for download on this website.


Why have audits?

Radio licence audits and transmission site audits are RSM’s proactive way of maintaining the integrity of the Register of Radio Frequencies (the Register). This minimises the likelihood of interference as well as the costs associated with legal compliance action.

Proactive auditing provides RSM the opportunity to:

  • Ensure that the transmission is authorised by a licence 
  • Ensure that licence conditions are met 
  • Promote sound management and engineering of radio licences and transmission sites 
  • Strengthen relationships with the radio industry 
  • Maintain the value and usability of the radio frequency spectrum in New Zealand.


What is the auditing process?

RSM selects licences to be audited with emphasis on high risk services and “at risk” sites. Most licence audits are conducted over the air, minimising costs to licensees. For site audits and licence audits requiring site access, i.e. power measurements, the audits are planned in advance and the auditee is given sufficient notice to make suitable access arrangements. If a serious risk to radio communications has been identified, or interference is occurring, a Radio Inspector may arrange to conduct an audit immediately.

Audits are conducted to minimise disturbance to the radio spectrum and maintain the integrity of the compliance framework, while optimising use of RSM compliance resources.

During an audit, the Radio Inspector may conduct measurements and record details including:

  • Measure transmitter power, frequency, bandwidth and emission characteristics
  • Check with a GPS of locations and altitudes to confirm grid references 
  • Note all transmitters, receivers and associated equipment 
  • Note antenna type, polarity and azimuth and height above ground 
  • Note coaxial cable type and length 
  • Photographs of transmitting equipment or site.


Your checklist to prepare for an audit of your radio transmitter(s):

  • Do you have a current licence? 
  • Is the transmitter located at the licensed location? 
  • Are all licence conditions complied with, including frequency, power, bandwidth, emission type, antenna polarisation and radiation pattern?
  • Is site access available? 
  • Are there any safety issues to be considered? 
  • Have any other affected parties (site owner, co-users) been notified?
