Barbara June Hayden is a New Zealand marine biologist, and is Chief Scientist at the National Institute of Water and Atmospheric Research (NIWA), specialising in marine biosecurity and aquaculture. In 2019 she was elected a Companion of the Royal Society Te Apārangi and awarded the New Zealand Marine Sciences Society Award.

Hayden grew up in New Plymouth, and gained a technical degree from Massey University.^[1] Working at the National Health Laboratories (now ESR), Hayden was responsible for assessing public safety of cultured shellfish, which led to her taking a job at the Fisheries Research Division of MAF.^[1] Hayden completed a PhD titled Factors affecting recruitment of farmed greenshell mussels, Perna canaliculus (Gmelin) 1791, in Marlborough Sounds at the University of Otago.^[2]

Hayden pioneered research on aquaculture and marine biosecurity.^[3] Hayden established the Ballast Water Working Group in 1987 in order to better manage concerns around biosecurity risks to aquaculture from introduced species from ship ballast waters.^[4] She was a founding member of the New Zealand Sanitation Committee, which drew up quality assurance guidelines for exported shellfish.^[4] Hayden was appointed Chief Scientist of NIWA's National Centre for Aquatic Biodiversity and Biosecurity in 2010, taking over from Don Robertson.^[4]

Hayden has been both Chair and Deputy Chair of the Biosecurity Ministerial Advisory Committee.^[4][5] She is a member of the International Union for Conservation of Nature Invasive Species Specialist Group.^[4] Hayden also serves on the Science System Advisory Group, advising the Ministry of Business, Innovation and Employment on the redesign of New Zealand's science system.^[6]

Hayden was elected a Companion of the Royal Society Te Apārangi in 2019.^[5]

In 2019 Hayden was awarded the New Zealand Marine Sciences Society Award "for her substantial contribution to marine science in New Zealand over a long and distinguished career that has included setting strategic research directions, leading major research programs, and mentoring emerging researchers".^[3]

Hayden is married to Dave Schiel, professor of marine science at the University of Canterbury.^[1]
