The Tawaki Project based at the University of Otago and driven by the mahi of international researchers, has taken a deep-dive into the population genetics of three Aotearoa crested penguin species – tawaki/Fiordland penguins, erect-crested penguins, and Eastern rockhopper penguins.

Findings reveal how genetic health and marine habitat changes have impacted these species.

For this week’s Green Desk, Host Sara spoke with co-leader of the project, Dr Thomas Mattern about what the study learned about these penguin populations, starting with a general overview of the research

A secret memo by the Ministry for the Environment intended for the central government reveals advice that New Zealand’s failures on climate action may negatively impact our diplomatic relations. 

The warning stated that, as New Zealand delays decisions and action on our commitments under the Paris Agreement, we may risk undermining our key alliances with countries like Australia, Canada, the UK and countries in Europe. 

More importantly, University of Auckland Associate Professor Maria Armoudian, director of Centre for Climate, Biodiversity and Society, says that our climate failings are reflective of a global “tragedy of the commons”, which will have urgent negative impacts for our Pacific neighbours.

For this week’s Green Desk, Sara spoke with Armoudian about this Ministry for Environment warning and how New Zealand should be seeking to improve its climate policies. 

She started by asking what her expectations and hopes are about the government’s response to this memo

Have you ever thought about what happens to all the food, which, while perfectly edible, simply doesn’t make it to the table? This week, the Green Desk delves into the growing issues of food waste, food insecurity and social isolation, and discusses how they can all be remedied by making better use of the perfectly good food that would otherwise end up in the bin. 

Everybody Eats is an organisation founded in 2017 which rescues surplus food items from charities and businesses and converts them into restaurant style food. They have a pay-what-you-can mode, with the aim of making this food accessible to all. 

Ahead of Earth Day 2025, Green Desk Producer Liam spoke to Amanda Butland, the Systems and Support Manager at Everybody Eats, about the current food waste crisis and what we could all learn from the Everybody Eats ethos.

BirdCare Aotearoa is a wild, native bird hospital that works to rehabilitate sick and injured birds back into the wild.

For their upcoming event: ‘Bird Heros,’ a part of EcoFest 2025 on the 6th of April, the workshop will look at the best practices on rescuing wild native birds, and will include a tour of their bird hospital, which is not usually open to the public.

Fellow Green Desk Producer Liam, and News and Editorial Director Joel, went to the previous workshop over the weekend, and spoke to the Chair of the organisation, Kevin Furgeson, and volunteer Marina, and had a tour of their facilities. Thanks EcoFest!

BirdCare Aotearoa also has a fundraiser running to shed light on seabirds affected by street lights and brightly lit buildings across the city, affecting their migration patterns and causing birds, such as the protected Petrels, Shearwaters, and Prions, to fall and injure themselves. To support their clinical rehabilitation practices, you can support their campaign on givealittle.

Ever wondered what it would be like to bike in an Art Gallery? Well now you can, for the city is your gallery. In collaboration with EcoFest 2025 and various New Zealand artists, Bike Hubs have set up a Street Art Bike Challenge.

Repairing is something of a lost art form. Appliances are built to be replaced rather than repaired. In the age of outlets like Temu and fash fashion houses - Who repairs things anymore?

On today’s Green Desk, we’re heading to The Shed — a workshop hiding in Sandringham’s GribbleHurst Park where woodworkers and tinkers spend hours fixing broken things and building new ones from scratch.

On this week's Green Desk we have part two of a special on The State of Wellington, recorded down in the capital inside Parliament’s cafe.

If you’ve read the news in the past month, the capital is being buffeted by gnarly headwinds. Not off the Cook Straight but rather from pesky employees working from home. But are sunny days ahead for Wellington?
