NZ On Air is 30 years old! Over three decades, countless stories and songs reflecting New Zealand's culture and identity have been created, thanks to the organisation's investment of public funds. To celebrate this milestone, NZ On Air asked well-known Kiwis to reflect on a programme or song from the past 30 years that has stuck with them — then asked some of those who worked behind the scenes to provide their perspective. Plus Ruth Harley, the first boss of NZ On Air, describes how it all began.
