The Radiocommunications Act 1989 is the core New Zealand law for managing the radio frequency spectrum. It is a principal Act and remains in force.
For businesses, the Act has three practical jobs. First, it creates legal pathways for using frequencies through management rights, spectrum licences and radio licences. Second, it regulates interference and technical limits. Third, it sets up the register, enforcement tools, fees, offences and evidence rules that support the system.
This means the Act is not just for large network operators. It can affect any business that transmits radio waves, installs radio systems, sells specialist transmitting equipment, or buys and sells spectrum-related rights.
