She served on the Academic Council of the Royal Society of New Zealand, the Marsden Fund Council, and the New Zealand National Science Panel.[2][8] She is an associate editor of Psychological Review and of the New Zealand Journal of Psychology.[8][10]

During Hayne's tenure as Vice-Chancellor, staff numbers (FTE) increased from 3,749 in 2011 to 4,154 in 2020, her last full year as Vice-Chancellor.[11] Over the same period, student numbers decreased from 19,568 (EFTS) to 18,722, partly attributed to the introduction of an enrolment limitation system aimed at slowing growth and "giving priority to higher calibre students".[11] Hayne prioritised student support and wellbeing and undertook several initiatives to rein in the university's notorious student drinking culture.[11][12] Māori enrolments increased significantly during her term including in the medical programme.[11] She was close to her students and thanked them on her departure, writing 'My life has been made so much richer by knowing you".[11] The university's operating revenue increased from $592 million to $756 million during her tenure and net assets increased from $1.6 billion to $2.5 billion.[11] Several major capital projects were completed including a refurbished library building and new buildings for music, theatre and performing arts, dentistry, and the Christchurch School of Medicine following significant damage from the Christchurch earthquake.[11]
Hayne's tenure as vice-chancellor was associated with controversy regarding cuts to the university's humanities division. In 2017, she was accused of intimidating behaviour surrounding cuts to 16 full-time equivalent jobs in the division, and in 2018 following the decision to eliminate the entire Art History program.
[13][14][15][16][17] In these cuts she worked closely with then Pro-Vice-Chancellor of Humanities, Tony Ballantyne.
In early October 2020, it was reported that Hayne would be finishing her term as Vice-Chancellor at the University of Otago in 2021 to assume the position of Vice Chancellor at Curtin UniversityinPerth; before completing her second five-year term at Otago University.[18][19] Her successor as Vice Chancellor of the University of Otago is Professor David Murdoch.[20]
In 2017, Hayne was selected as one of the Royal Society Te Apārangi's "150 women in 150 words", celebrating the contributions of women to knowledge in New Zealand.[22] In 2021, she was conferred with an honorary Doctor of Laws degree by the University of Otago.[23]
