The Bioethics Roadshow hit Wairarapa on Monday to explore ethics and the science of life and death.
More than 160 students from Solway College and St Matthew's Collegiate School attended.
Rozleen Chand, Solway College head of science and careers advisor, said the roadshow featured a team of graduate students and Otago University lecturers led by Dr Lynne Bowyer, who took the Year 8 to Year 10 students through a multimedia array of science topics and "ethical issues concerning the beginning and end of life".
Ms Bowyer sought through the roadshow to take "contemporary bioethical issues into New Zealand schools in order to stimulate informed, critical thinking with high school students", according to the Otago University website.
Ms Chand said the visit was the second project she had co-ordinated to help promote science study among students "and to get them to think about science as their future and a possible career".
