Adam Thompson

Waikato

Adam Thompson is a conservationist and sustainability advocate who has built a wide-reaching community dedicated to protecting native ecosystems. A passionate champion for two of the things New Zealand is best known for – our farming sector and our precious endemic wildlife – Adam is naturally gifted at rallying people around a cause: driving positive change with a strong focus on education and community.

His Cambridge-based nursery, Restore Native, has distributed millions of native trees across New Zealand’s North Island, transforming farms and landscapes to improve water quality, biodiversity, and soil health. As a founding member of Predator Free Cambridge, Adam actively leads community projects to protect endangered birds, restore kiwi to the Waikato, and improve predator control nationwide. His most recent community pest control project in his home town of Te Miro, hopes to bring Kiwi back to the district over the next 5 years.

Over the past few years, Adam has gone above and beyond – sending over 37,000 plants to Tairawhiti Gisborne and Te Matau-a-Māui Hawkes Bay to help cyclone recovery over the course of 2023 and 2024. Closer to home, Adam sent 100 trees to every rural school in the Waikato district – helping kids connect with their whenua. His mahi is a true gift to future generations, blending conservation with community care.

Barry Coates

Auckland Tāmaki Makaurau

Barry Coates, founder and CEO of Mindful Money, is a passionate advocate for ethical investing and sustainability in New Zealand and internationally. Through Mindful Money, Barry has raised awareness about the social, environmental, and ethical implications of investment choices, particularly within KiwiSaver funds. Under his leadership, Mindful Money has highlighted companies violating ethical standards, empowering KiwiSaver investors to find a fund that aligns with their values and encouraging fund managers to avoid harmful investments and seek to invest for good.

The impacts are tangible: as an example, Mindful Money convinced KiwiSaver fund managers to avoid investing in nuclear weapons production. As a result, investment in nuclear weapons dropped from $100 million in 2019 to below $15 million in 2024. Barry’s leadership – often in the face of deeply entrenched attitudes about investing – has not only transformed consumer awareness in Aotearoa, but has also made real impact for global communities, redirecting capital away from harmful activities and towards positive impact. Overall, his mahi empowers individuals to drive global change – aligning their investments with a vision of a more ethical, sustainable future for all.

Dan Henry

Wellington Te Whanganui-a-Tara

Dan Henry is the driving force behind Predator Free Miramar, an initiative he co-founded in 2017 aimed at eradicating introduced predators from the peninsula. Under Dan’s leadership, this community project has blossomed from a small group of dedicated trappers to a thriving network of over 1,000 households, successfully removing more than 10,000 predators and allowing native wildlife to thrive. Dan’s hands-on approach includes personally delivering traps, training residents, and hosting community events, which has fostered a strong sense of shared purpose and pride among locals. His efforts have led to a remarkable resurgence of native bird populations and increased sightings of wildlife like mokomoko (lizards) and wētā.

Working alongside Predator Free Wellington, Dan and his team of volunteers have not only eliminated rats from the Miramar Peninsula – a world first in an urban environment – but they have successfully maintained that Predator Free status for more than a year.

By creating a safer environment for New Zealand’s unique biodiversity, Dan’s work has not only benefited the ecosystem but also strengthened the community, making Miramar a more connected and vibrant place to live. His commitment to this cause embodies the spirit of community action and environmental stewardship.

Joel & Awhina Ngātuere

Bay of Plenty Te Moana a Toi

Joel (Ngāti Kahungunu ki Wairarapa, Rangitāne o Wairarapa) and Awhina Ngātuere (Ngāi Te Rangi, Ngāti Ranginui, Te Whānau a Apanui) from Mt Maunganui are true champions for their community, advocating restlessly to protect the air, land, and water for the people they love and wider community. For almost a decade, they’ve worked on behalf of their hapū to uncover and fight against hazardous pollutants around their marae.

Their battle began when they noticed concerning illnesses among kaumātua and tamariki, which they traced back to toxic contamination in the area. Despite resistance from local councils and corporations, the Ngātuere family persisted, educating and rallying their people and communities, engaging in numerous environment court proceedings, presenting to the United Nations, sharing their story with the media, and holding wānanga to spread awareness. Their findings – recently backed up by the discovery of harmful PFAS chemicals and ESR Health Report – highlight the severity of pollution affecting the area and residents of Mount Maunganui.

Their work has led to changes in spatial planning, socialising discussions between communities, councils, and industries for both improving sustainable practice and industrial retreat from the Mount Maunganui peninsular. Additionally, Joel and Awhina are ensuring that councils and industry alike are blending Mātauranga Māori with modern Western science to restore the land and improve environment outcomes. Through their resilience and a deep love for whānau, Joel and Awhina inspire others to take action and protect our environment for future generations.
