Matthew Clifford

Junior Consulting Arborist

Matthew has been with The Tree Consultancy Company Team for several years, with a primary focus of undertaking monitoring and supervision of development and construction sites.

He entered the arboricultural industry in 2011, starting out as an apprentice for his local Council in the United Kingdom. Two years later, he had completed his apprenticeship and moved into a tree surveying role with the council. Here he provided tree risk assessments along with processing tree related enquires from the public.

Matthew moved to New Zealand and began working at The Tree Consultancy Company in August 2019. His primary role within the company is to monitor projects to ensure that they comply with consent conditions.

His aim is to provide clients with relevant and practicable arboricultural advice on topics such as the effect a proposed development may have on trees in the area, and how best to retain them and incorporate them into the finished design.
