One from the archives! By the 1990s Chatham Island tūī had all but disappeared from the main island. Slightly different to their mainland counterparts, these songbirds had survived on nearby Pitt and Rangatira islands. So a local conservation group decided to try bring them back. In this episode from 2010, Alison Ballance joins the ‘tūī team' tasked with moving 40 birds from Rangatira island back to the main island.

Cooper's orchid is New Zealand's rarest and most elusive, with fewer than 250 plants left in the wild. It belongs to the group of potato orchids, which grow mostly underground as tubers – except for a brief period every few years when they push out a leafless stick with a few flowers. This largely subterranean lifestyle already presents a challenge, but saving this species is even harder because, like all orchids, the Cooper's orchid can only produce seedlings with the help of the right soil fungus. After years of lab experiments to produce in vitro seedlings, botanists are now ready to boost dwindling wild populations.

Our Changing World joins a group of botanists during their first ever attempt to reintroduce our rarest and most elusive native orchid back to the wild. New Zealand's native orchids are much more modest than the showy plants you can buy in the shops. But this one – a potato orchid known as Cooper's orchid – takes modesty to the extreme. It lives mostly underground as a tuber – a bit like kūmara or dahlias – and only emerges briefly every few years to push out a leafless stick with small brown flowers. Like all orchids, it only survives with a lot of help from a fungus, which means that botanists had to use in vitro propagation methods to produce seedlings.

Kākahi are a keystone species in lake and river ecosystems, keeping the water clean by filtering one litre of water every hour. These native mussels once blanketed lakebeds across Auckland – but recent surveys found an alarming decline and disappearance across many lakes. A team of scientists and divers have mounted a rescue mission for one of the last remaining kākahi populations, trying to keep the mussels safe from invasive fish through all the steps of their complicated – and fascinating – life cycle.

Human-induced climate change is impacting Earth's global systems, including ice melt in Antarctica. What is the world doing to combat it? Signed in 2016, the Paris Agreement is the current global plan to tackle it. Countries pledge different emission reduction targets and then produce their workings and homework about how they are going about it. Where does New Zealand fit in? Are we doing our bit as a nation?

In February 2025, the world hit a new low for global sea ice extent. Arctic sea ice has been declining for several decades now, but Antarctic sea ice had been holding steady, until recently. With low summer sea ice extents for four years in a row, it appears that Earth's warming has kicked Antarctic sea ice into a new regime. Claire Concannon speaks to scientists to understand what this means for Antarctica, what this means for us, and how they feel about it.Guests:Dr Natalie Robinson, NIWA Dr Jacqui Stuart, Victoria University of WellingtonDr Greg Leonard, University of OtagoDr Daniel Price, University of Canterbury and Kea AerospaceDr Inga Smith, University of Otago Dr Michelle LaRue, University of CanterburyLearn more:Read about the recent State of the Global Climate Report.The world's biggest iceberg recently ran aground, but to get up close and personal, listen to the Voice of the Iceberg miniseries.The world is also experiencing ice loss from its glaciers.

Step out on the sea ice just outside New Zealand's Scott Base with researchers studying the physics of its annual cycle. Each year a massive patch of ocean around Antarctica freezes and then melts again come summer – Antarctica's heartbeat.

New Zealand's tuatara are the last remaining species of an order of reptile that was alive alongside the dinosaurs 240 million years ago. The rest died out about 65 million years ago, but in Aotearoa the tuatara live on, found on 32 offshore islands and in a small number of ecosanctuaries and zoos on the mainland. Now one researcher is investigating the microbial community that lives inside their gut. Are there also bacterial ‘living fossils' to be found?

Dive under the Antarctic sea ice near Scott Base into the weird world of cold-water life. Pink sea angels, worms that look like intestines, ocean creepy crawlies that get as big as your hand... and mysterious giant glass sponges. These sponges are one of the strangest, and oldest, animals on Earth: surviving without light, eating bacteria and viruses, and making themselves out of silica they absorb from the water. In most parts of the world, they live at depths too deep to dive, making them tricky to study. But in the cold waters of McMurdo Sound, they can be found in shallower waters. Now an international team of scientists are unlocking some of their secrets.

Our Changing World goes in search of one of Aotearoa's rarest plants – the stunning kakabeak, or ngutukākā.  Its clusters of bright red blooms, each shaped like a parrot's beak, make it a popular garden plant. But in the wild, ngutukākā is barely holding on. Considered “nationally critical” by the Department of Conservation, only about 100 individual ngutukākā plants survive, clinging to exposed steep bluffs where goats and rabbits can't get to them. But now, locals along the East Coast, the kakabeak's last stronghold, are determined to reverse its march towards extinction by propagating wild plants to turn State Highway 35 into a crimson highway. Veronika Meduna joins them for the inaugural Ngutukākā Festival.

The host of RNZ podcast Our Changing World joins Emile Donovan to share about her upcoming trip to Antarctica, what the 'solar maximum' is, and the big pot of research funding called Horizon Europe. 

Humanity has had a long and vexed relationship with the element lead. The problem is the stuff is terribly useful – and terribly toxic. Think Roman water pipes, lead paint, lead petrol. Now, new research is adding to a global body of work showing that there are more downsides to using lead in ammunition than we previously realised. Our Changing World's Alison Ballance is in Nelson to find out more. 

Thomas is joined by internationally recognized speaker, author, and expert in the field of attachment theory and trauma resolution, Dr. Diane Poole Heller. They discuss Diane's work in attachment theory, exploring how our early experiences with our caregivers affect our attachment styles, and what we can do to move into secure attachment in our relationships. Dr. Heller views trauma as a broken connection—with ourselves, our lives, the earth, or other people—and explains how therapists and healers can co-regulate and attune with their clients' nervous systems to create a safe environment for transforming trauma. Dr. Heller believes that we can interface with the energy of trauma in a way that doesn't cause overwhelm, and opens us to maturation, spiritual experiences, and changes in consciousness. She and Thomas also discuss how working collectively in a group amplifies healing, and how all therapists and healers are ultimately agents of grace. ✨ Join Thomas for Collective Resilience: Healing Together in Our Changing World.

Mark Leishman catches up with host of RNZ's Our Changing World  to hear about her recent adventure to the Australian synchotron.

Thomas shares deep insights into how we can embody the soul's wisdom and increase our capacity to be present and form a deeper alliance with life. He shares tools and practices for becoming more grounded and spacious in our daily lives, and in challenging situations, and how that gives us the courage, curiosity, and strength to turn difficulties into growth, expansion, and wisdom. He also offers embodiment practices to help us connect our physical and emotional data streams, creating a more coherent awareness of our internal processes, and increasing our natural intuition and capacity for change.  As Thomas explains, we are all part of an interconnected world, but trauma tends to create a sense of separation. Reconnecting to the essence of life helps us develop a deeper sense of ourselves so that we can achieve greater regulation and resilience. ✨ Join Thomas for Collective Resilience: Healing Together in Our Changing World.
