In a letter to the Radio Spectrum Management Policy and Planning manager, the New Zealand Association of Radio Transmitters (NZART) request an amateur radio allocation at 222-223 MHz
NZART is always on the lookout for spectrum that has different characteristics from that to which we already have access. The 174 to 230 MHz band clearly fits in this category – having characteristics quite different from the two adjacent (144 MHz and 430 MHz) amateur bands.
NZART have requested that the small allocation (222 – 223 MHz) be made available to the NZ Amateurs to allow them to further both the self-training and technical investigations purposes of the Service.
