4ZB
New Zealand radio station
4ZB was an adult contemporary radio station in Dunedin, New Zealand.
History
Early years
The station was started by the New Zealand Broadcasting Service in 1937 originally broadcasting on 1040AM. The station was branded from the stations callsign 4ZB. ZB stations were assigned to the four main regions in New Zealand, Auckland, Wellington, Christchurch and Dunedin. While content was local some network shows were heard such as Aunt Daisy up until 1963. In 1978 the station moved to 1044AM after New Zealand changed from 10 kHz spacing on the AM band to 9 kHz spacing. From the 1970s programming was extended into Central Otago on 640AM (callsign 4YW) and Queenstown (callsign 4YQ) on 1120AM, these stations moved to 639AM and 1134AM, respectively, in 1978. The Queenstown and Central Otago stations ran a mixture of National Radio and 4ZB programming. Both Queenstown and Central Otago frequencies were later used to solely broadcast RNZ National, however they were both switched off in April 2019.
Switch to FM
In September 1990 4ZB switched to FM, broadcasting on 89.4FM and became known as ZBFM. 4ZB continued to use the AM frequency and launched a parallel station called 4ZB The Talk of Dunedin. Both stations ran the same breakfast show but following the breakfast show programming on the AM frequency had a talkback focus including community news and easy listening music.
Rebranding as Classic Hits 89FM
In 1993 Radio New Zealand rebranded many of their heritage stations as Classic Hits.

Why this record matters
“4ZB” is worth following because a concise public description often conceals a longer documentary argument. Here, Zealand, radio and station provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Feb 19, 2026. The linked authority identifier is Q20312918. Authority coordinates are -45.873, 170.505. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1937, 1963, 1978 and 2019.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
