Our Trustees

Gillian Bishop 


Gillian has chaired Tasman Environmental Trust since 2016. She lives beside the Waimea Inlet and has been involved in a wide range of work to protect and enhance the environment, through both practical work and as a trustee. Gillian’s background in contract development and management is invaluable as the Trust enters into an increasing number of arrangements with community groups, local councils and government organisations to deliver conservation projects.
Gillian is keen to see community groups supported by TET’s Community Conservation Hub services to enable them to focus on planting, weeding and pest control in their local areas. Her work in conservation was recognised in 2020 when she was awarded a QSM.

Marian is currently employed part-time for the HealthPost Nature Trust as project co-ordinator, and also manages to fit in some DOC contract wildlife monitoring, volunteering, and a little bit of vet locum work. Marian is the current chair of Project Mōhua’s management committee, linking Golden Bay into the TET family.

Murray Poulter

Dr Murray Poulter, originally from Motueka, is a former NIWA Chief Scientist who now resides on a small block in Tasman. His research career included work in the UK, Germany, US, Canada and Antarctica before he took on management roles in NIWA.

Murray is joint owner of a QE II covenanted plot of native bush. He has a keen interest in the local environment and an appreciation of the impact co-ordinated community efforts can bring.
