Mark Delaney

Senior Ecologist

MSc (Hons) Conservation ecology, BSc (Geography and ecology)

Specialising in

  • Freshwater ecology
  • Stream ecological valuations and stream and waterway conservation classification
  • Terrestrial ecology
  • Development impact assessments


Mark is a freshwater specialist evaluating and classifying streams and waterways in the path of motorway, road, subdivision and quarry developments, relocating fish and specifying work needed to restore streams after development.

Growth in New Zealand’s biggest city means a lot of his conservation work focuses on Auckland and its hinterland, where he says development is putting a lot of pressure on streams and their inhabitants. He works with developers to advise them on undertaking development in a sustainable way.

Mark completed his BSc at the University of Auckland in 2005 and his master’s from Massey University in Albany in 2009, he has contracted for Auckland Council and the Department of Conservation – and also spent two years overseas crewing on a superyacht – and joined Bioresearches in 2015.

Mark recognises ongoing development is necessary but says the key is finding the right way to go ahead without degrading the environment.
