Who We Are


Edwin Ainley


Following the completion of a Bachelors degree in Science, Edwin spent a few years in Nelson working in ecological restoration. Major projects in this area included restoring a native wetland and native forest areas; pest plant and predator control. He also completed the development of two fish swim ways to allow the movement of native fish upstream. In 2010 Edwin returned to the education world to complete a Post Graduate Diploma in Environmental Science and a Masters of Science in Marine Ecology.

He has spent the last five years working in biosecurity response, managing a variety of eradication programmes for terrestrial and marine organisms, such as the Queensland fruit fly incursions.

In his spare time Edwin enjoys a lot of sports, especially rugby. He loves being on or under the water, particularly surfing and fishing, and recently completed PADI dive masters.



Sam Russell


Sam Russell holds a Bachelor of Science degree in Geography from the University of Auckland, and has since gained valuable experience in ecological restoration here at Te Ngahere, working roles within the field from team member to team leader positions.

His experience includes time working across Auckland’s parks, as well as the Islands of the Hauraki Gulf. Sam has spent 4 months living on Hauturu / Little Barrier Island as part of the weed team, as well as participating in weed control and rodent eradication on other islands of the Gulf. He is a part of our health and safety committee, and is committed to ensuring a safe work environment for all.

Sam spends as much of his time as possible either on or under the water – a keen surfer, fisherman and diver.

Outside of work, Richard enjoys bird watching, tramping, foraging and growing natives and vegetables.


Anna Mairs


Anna has worked as a field worker and later joined our strong consultancy team as an ecologist.

After completing her Master of Science in Environmental Science (Applied Ecology and Conservation), Anna worked in ecology, conservation and biosecurity based roles in New Zealand and the United Kingdom, with work ranging from bird surveys in the Scottish Highlands to writing restoration plans for Auckland’s urban reserves. Her key interests are restoration and weed ecology.

Anna brings both practical understanding and technical knowledge to projects with experience in developing management plans, undertaking ecological surveys and assessments and project management.

Passionate about the environment, Anna regularly enjoys hiking, conservation volunteering, bird watching and growing native plants.
