RANGITAIKI, New Zealand — Radio New Zealand Pacific, the official international arm of Radio New Zealand, is using Digital Radio Mondiale digital radio transmission/reception equipment to feed studio-quality audio to some of its 20 relay stations in the Pacific Ocean region. The others use satellite feeds or web downloads.

The locations being served by DRM include the Cook Islands, where RNZ Pacific's programs are rebroadcast locally in analog mode by Aitutaki 88FM, the islands' only broadcaster. RNZ Pacific also serves Tonga, Samoa, and the Solomon Islands using DRM; among others. Previously, RNZ Pacific had fed its relays using analog AM shortwave radio, with that transmission mode's limited audio range and interference issues.
