AM and FM Frequencies

We have AM and FM transmitters covering a large percentage of New Zealand.

RNZ National broadcasts on both AM and FM (101FM) in most areas.

RNZ's AM Network broadcasts all sittings of Parliament on AM. When Parliament is not sitting, the transmitters carry the Star network from the Radio Rhema Broadcast Group.

Mono and Stereo

Radio NZ National is broadcast on FM in mono as it's more cost effective than stereo. As our highest-rating programmes (news and talk programmes) are in mono and are listened to by many people on mono radios, we believe it is better to broadcast to more listeners in mono than fewer in stereo.

There are some advantages of being in mono: reception is better because the radio is not trying to decipher the complex stereo info; and as mono requires about a sixth of the power of stereo, there is less overloading and distortion from high power signals reflecting off buildings.

However, on our internet streaming audio from the website, our RNZ app and iHeartRadio, both RNZ National and RNZ Concert are in stereo for the live stream and for selected music programmes.

RNZ National and RNZ Concert are in stereo on Freeview terrestrial.

Radio Data System (RDS)

RNZ uses RDS technology on some of its FM transmitters.

There are two key reasons we transmit RDS:

  1. When you tune in to most RNZ National FM transmitters on an RDS-capable radio it will display "NATIONAL" or "CONCERT" so you know its us.
  2. Your vehicle radio will automatically retune to the best available signal as you drive. For example, if you drive between Auckland and Hamilton your radio will change frequency as you drive over the Bombay Hills

You may need to enable 'RDS' or 'AF' on your vehicle's radio, to allow it to change automatically. Refer to your vehicle's car-radio manual for more detailed information.

For technical reasons, RNZ doesn’t transmit any time info on its RDS.
