Radio Nelson was a New Zealand radio station in Nelson. The station was started by Radio New Zealand (which at the time was known as the New Zealand Broadcasting Board) in 1932. The station originally broadcast on 1340AM with the callsign 2ZR. The station changed call signs to 2YN followed by 2XN and finally 2ZN. In 1978 the AM band in New Zealand was adjusted from 10 kHz to 9 kHz, as a result 2ZN moved to 1341AM. Originally the station was branded by its callsign name and did not become known as Radio Nelson until the 1980s.
