"Everyone got tired and hungry and everyone went through that stage of wanting to go home - even me - but the team support kept me and the others going and we all just carried on," she said.
"We were a lot more united as a group when we got back."
Alataua Wilson, 17, second in command, said he had joined the academy to improve his physical fitness and as a career boost toward studying physical education and owning and operating his own gymnasium.
Mr Wilson plays in the front row for the college 1st XV and the Marist Thirds club side, he said, and his fitness level had lifted since he started at the academy.
He said the most difficult element of the course for him had been the Longest Day, which was held on the 10th day of the boot camp, testing all that had been learned up to that point.
This included a Required Fitness Level test that comprised a 2.5km run, adventure-based learning tasks, teamwork, fieldcraft, fire drill and safety, and leadership skills.
Hannah Smith, 16, said she also was looking at a career in the Navy and had profited from the boot camp, especially the team events and tests.
"When we started working as a team, things got better because teamwork was essential otherwise you just start falling apart."
Jamie Murdoch-Dawson, 17, said a military career was a possibility for her and she had joined the academy to gain fitness and an introduction to the military.
She agreed with Mr Wilson that the Longest Day, and the exhaustion towards the end of that day, were the most difficult challenges on the course.
Rima Marurai, director of the Makoura College Services Academy, said there were a further four courses the students would attend throughout the year.
