The course called Raising the Standards was run by NZ Young Farmers and funded by DairyNZ.
It was designed to enhance the skills of emerging leaders within high school TeenAg clubs.
"The aim is to increase students' awareness of opportunities in the primary industries while helping to hone their leadership skills," said Mary Holmes from NZ Young Farmers.
"They learned about different graduate programmes, the wide range of agri-related scholarships on offer and how some agri-businesses encourage secondments overseas."
Students heard from numerous guest speakers, including agri-business bankers, consultants, an agronomist, a dairy farmer and a vet.
The group toured Fonterra's dairy factory in Reporoa, which produces a highly nutritious product used in hospitals for sick patients called sodium caseinate.
"It was really interesting. It was eye-opening to see that there's more to the dairy industry than milking cows," he said.
"I knew there were other jobs in processing and research, but not on the scale we saw."
A highlight of the course for Gurr was developing new networks and meeting students from other TeenAg clubs.
"I met a guy who lives 20 minutes down the road from me. We go to different schools and didn't know each other before the course," he said.
