This paper presents research on the returns to tertiary education for individuals who graduated between 1997 and 2008 with bachelor degrees from universities and polytechnics in New Zealand based on their experiences post study. It examines data on their post-study earnings drawn from two longitudinal datasets linking administrative data on individuals' tertiary education records to their earnings. An advantage of this research is that it reports on differences in the earnings of those who studied in specific fields of study at polytechnics and universities. The data are used to help shed light on the importance of reputational capital in reproducing social classes. (Contains 4 notes, 3 tables, and 2 figures.)
