Grey Areas with Petra Bagust

TJ Power is the best-selling author of The DOSE Effect and a neuroscientist who teaches people, young and old, how to fix their brains. By paying attention to how we’re wired, and what we spend our time doing, we can change our brain chemistry in remarkably simple and effective ways. In our social media-soaked frantic society it’s easy to accidentally ‘hack’ our motivation getting cheap rewards that don’t last and lead to addictive and unfulfilling behaviours. In this chat TJ gives us plenty of tips for how to get our brains back on track to feeling and functioning fabulously.

In this interview, I sat down with beloved kiwi musician Stan Walker. Our conversation covers his multidimensional career, his journey with identity, the importance of maintaining boundaries, and protecting his peace. He speaks openly about his growing understanding of forgiveness, the effects of trauma, and the long-term process of healing and self-acceptance. Stan also emphasises his dedication to his family, health, and bringing hope, life, healing, and joy through his music. I really admire Stan for his vulnerability, honesty and courage and I’m so excited to share this kōrero with you all. This episode covers some confronting topics, including sexual abuse.

In part two of my conversation with Dame Anne Salmond, we go deeper - into wānanga (the meeting of ideas), into te ao Māori (Māori worldview), and into the kind of thinking that could help us live better together. Dame Anne speaks about her decades-long relationship with her Māori mentors, Eruera and Amiria Stirling, and how those relationships rewired her understanding of the world. We talk about what it means to live in a relational way - and how te reo Māori doesn’t just name the world, it can reshape it. This kōrero makes space for where anthropology meets awe, and scholarship meets soul. We also talk about tapu and mana, and how those concepts aren’t just beautiful - they are power filled. We discuss Te Tiriti o Waitangi, not as a document of rights and rules, but as a sacred gift exchange rooted in respect. We touch on binary thinking, politics, creativity, and the purpose of universities - and why the best ideas are born in spaces where words can be blown about by the wind and shone on by the sun. This conversation is a gift. It’s a call back to care, and forward into complexity, beauty, and balance.

In this episode I sit down with biochemist Dr Libby Weaver, a nutritionist, speaker, and author of 13 books (soon to be 14). Libby brings a holistic lens to wellbeing, combining science, nutrition, and emotional insight in a way that’s both practical and also deeply human. We explore the gap between what we know and what we do, and why that gap exists. Libby unpacks the power of belief systems – how they quietly shape our choices, our habits, and even our health. We talk about stress, sugar cravings, hormone changes, perimenopause, self-talk, and the importance of iron, all woven through with her gentle encouragement to be curious, not critical. What I loved most is Libby’s message that our bodies are not betraying us – they’re whispering to us. And if we pause to listen, we might just discover the kind of deep wisdom and clarity we’ve been hunting for in all the wrong places. This kōrero is science-meets-soul, and a gentle nudge toward greater kindness – to ourselves, and to our brilliant, hardworking bodies.
