In a media landscape often crowded with quick takes and fragmented attention, 30 with Guyon Espiner offers a deliberate alternative. Each episode is built around a single, extended conversation between veteran journalist Guyon Espiner and one person shaping the world we live in. The focus here is on depth, not breadth, allowing for a nuanced exploration of a guest's ideas, experiences, and motivations. As a production from RNZ, this podcast carries a commitment to substantive journalism, presenting these dialogues without editorial cuts or interruptions. What you hear is the full, unfolding discussion-the thoughtful pauses, the challenging questions, and the moments of genuine insight that can only emerge from a sustained, thirty-minute exchange. The guests are drawn from across spheres of influence, including politics, academia, culture, and activism, providing listeners with a direct line to perspectives that inform public life and private conviction. Tuning in means setting aside the noise for a half-hour of focused listening, where the format itself-one guest, no edits-becomes a statement of intent. It’s for anyone who believes that understanding complex figures and issues requires more than a soundbite, preferring instead the texture and authenticity of a complete, unrehearsed conversation.
