How do you go about dissecting the world’s rarest whale? In December 2024, images from a concrete room in Mosgiel, just south of Dunedin, spread around the world as a team of people spent a week doing a scientific dissection on a spade-toothed whale that had washed up five months before. Claire Concannon joins them to find out what’s involved, what they have learned, and how the arrangements between local iwi and visiting scientists enabled knowledge sharing.

The missing black petrels of Great Barrier Island
For nearly 30 years, researchers have been banding black petrel fledglings before they make their maiden migration to Ecuador. Only a handful of birds have ever come back.
RNZ’s In Depth reporter Kate Newton travels to Aotea-Great Barrier Island to meet the birds, and the dedicated team trying to figure out the mystery of where they go.

The 2024 Prime Minister’s Science Prize winners
Each year, five Prime Minister’s Science Prizes are awarded in the most prestigious New Zealand science awards. We explore the AgResearch science that got the top recognition this year and catch up with two of the other winners. Science Communication prizewinner Professor Jemma Geoghegan talks about the hundreds of interviews she’s done about viruses, and Future Scientist prizewinner Rena Misra explains her project exploring how a plant-fungus combination could have the potential to help clean up stormwater.

Fiordland's underwater world
With its steep sides, forested slopes and heavy rainfall, Fiordland has interesting ecosystems both above and below the water. Below the surface of the inner fiords, a variety of sponges, corals, and other filter-feeding animals cling to the cliff-like reefs. Claire Concannon heads to Doubtful Sound with a research team who are habitat-mapping the fiords to better understand what’s there, and how things are changing over time. They are also investigating the resilience of its iconic black corals to local landslides and marine heatwaves.

Helping New Zealand’s understated orchids
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. Guests:Dr Carlos Lehnebach, botany curator, Te Papa TongarewaDr Karin van der Walt, conservation advisor, Ōtari Wilton’s BushJennifer Alderton-Moss, plant conservation researcher, Wellington City CouncilLearn more:Read the article that accompanies this episode: Rare orchids reintroduced into the wild.Alison Ballance talked to Carlos Lehnebach about why some orchids smell like mushrooms and how that helps them to fool insects.This Critter of the Week episode focuses on the helmet orchid (Corybas dienemus), another rare native orchid that likes cold, damp and windy places.In this interview, Jesse Mulligan talks to Fred Clarke, a Californian orchid breeder who created the acclaimed black orchid After Dark.This Critter of the Week episode discusses the copper beard orchid (Calochilus herbaceous), which is threatened by habitat loss and climate change.Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more.Go to this episode on rnz.co.nz for more details
