After a decade on the air, Kiwi FM is shutting down at the end of the month.
The station initially played 100 per cent New Zealand music before moving to a 70/30 split with international music in recent years.
Mediaworks group content director Leon Wratt said in a statement that the company planned to focus on its other radio stations, George FM and Mai FM.
"There are now more options than ever to listen to home grown music, and it is time for us to focus on other priorities," he said.
About 28,000 listeners tuned into Kiwi FM every week and they were responsible for around one per cent of local music played on New Zealand radio stations.
The last day of broadcast in March 31 and the station frequencies will then return to the crown, Mediaworks said.
