Mr Hodgson, chairman of the Southern Partnership Group which is managing the rebuild, said he would remain on the company board of Otago Innovation and on its advisory committee.
He initially agreed to the chief executive position for three months in 2014, but ended up staying four years.
``I stayed that long because I fell in love with it, and because of the quality of investments at the University of Otago were very, very strong,'' Mr Hodgson said.
His replacement, David Christensen, was appointed at the beginning of this month.
Dr Martin Gagnon, chief operating officer of Montreal company Exactis Innovation, was appointed as new director of research and enterprise and will take up his role in early July.
Otago Innovation is involved in managing about 42 projects, and on average received about 50 projects a year to evaluate.
Many of the projects that had been funded through Otago Innovation related to health sciences.
Mr Christensen said he wanted to make the rest of the university aware of the commercial possibilities that existed for researchers.
``I want to broaden our reach, and not be pigeon-holed into one or two areas.''
