Massey University Chancellor Chris Kelly is stepping down, after earlier apologising for saying one woman veterinary graduate was worth two fifths of a full-time vet.
Mr Kelly made the comment in an interview with Rural News, published last week.
"When I went through vet school, many years ago, it was dominated by men; today it's dominated by women," Mr Kelly told the publication.
"That's fine, but the problem is one woman graduate is equivalent to two fifths of a full-time equivalent vet throughout her life because she gets married and has a family, which is normal. So, though we're graduating a lot of vets, we're getting a high fall-out rate later on."
He told the university today that he intended to step down from his position, effective immediately.
In a statement, Mr Kelly said his decision followed media coverage of his comments.
"Having had time to carefully consider the views of many staff, students and stakeholders, I believe that it is in the interests of the university that I step aside," he said.
