The veterinary school at Massey University marks its 50th anniversary on Friday with a symposium and other celebrations.
It opened in 1963, with an initial intake of 32 students.
Professor Frazer Allan said those student numbers have grown, along with Massey's international reputation for its veterinary teaching and research programme.
There are now 100 students in total and around 24 of them are international students and 76 of them are domestic.
Professor Allan said the school, the only one in New Zealand, is very well regarded and has international accreditation in Australia, New Zealand, Britain, the United States and Canada.
Some honorary degrees and medals will be awarded as part of the celebrations.
