Student exchange scholarships valued between $1000 and $3000 were awarded to 17 students.
Three scholarships are available - the Dean's Exchange Scholarship, the Westpac Travelling Scholarship and University of Otago Travel Grants - to help students study overseas for one or two semesters.
Ms Aarts won the top scholarship, for $3000, from Westpac to study in Chile.
Ms Aarts was excited about travelling to South America to use some of the Spanish she had learnt.
"I'm scared I'll like it so much I won't want to come back."
Exchange co-ordinator Bronwen Cooper said students benefited from breaking out of their comfort zones.
"You notice a difference in students when they come back. It's really incredible."
