Caleb Clarke is one of the directors of Morphum Environmental, and has seventeen years of experience in environmental engineering involving the delivery of a wide range of complex and integrative projects.

Caleb graduated from Unitec Institute of Technology with a Bachelor of Engineering (Environmental). He has wide experience in assessment, planning and strategy development for water cycle issues within the Auckland region, which has led to an extensive knowledge of environmental, technical, social, legislative and economic issues for infrastructure development.

From an early background in construction, stonemasonry and landscaping, and engineering experience in water treatment; wastewater network design and stormwater modelling and design focussed on streams, wetlands and water sensitive approaches, Caleb has developed a strength for practical and green engineering focused designs.

Caleb brings an appreciation of the risk and the complexity of water and environment issues to his design work at Morphum Environmental. He acts as an advocate for collaborative process to solve wicked problems, and innovation including use of strategic policy and management solutions in providing enhanced resilience and sustainability outcomes. A particular strength is communication and engagement, with a range of audiences. He is capable of conveying complex technical issues in an open and straightforward manner.

Caleb is the current chair and has been a committee member of the Sustainability Society, a technical interest group of Engineering New Zealand, since 2008. He has lectured in Hydrology and Urban Stormwater at Unitec and the University of Auckland since 2010. Father of two, Caleb is also a trustee on the AoteaOra Sustainable Social and Economic Development Trust on Great Barrier Island and a keen surfer, ocean swimmer, freediver and craft brewer.
