Fifty of the 53 University of Otago medical students found not to have met acceptable attendance requirements while on overseas placements will undertake remedial work, the university says.
The three remaining have been let off the hook, the university finding they did meet requirements "in the light of additional evidence".
"Details of individual remedial packages will be finalised with each of the students across December, and will require approval by the Otago Medical School," a statement said.
Each approved package would include significant additional community work, and possibly further academic work, to make up for missed time, provision of a reflective essay, and the resubmission of corrective elective reports "in any cases where these were misleading".
"Due to these ongoing remedial work requirements, the students will not be able to graduate in December.
