Head professor Philip Lindsay said the round robin competition was a chance for students to have a mock competitive environment.
While competing to get to the top of the leader board they would also have an opportunity to note what worked and what did not so they would know what to work on to improve their fighting skills.
Martial arts were about honesty and integrity, he said.
The aim was to be able to immobilise someone to the point when they had to yield, before causing harm.
Some members of the group were working towards the New Zealand nationals taking place in April.
Brazilian jiu jitsu emerged in Brazil in the early 20th century when Japanese immigrant Mitsuyo Maeda, a student of Jigoro Kano, taught members of the Brazilian Gracie family.
The Gracie family then went on to set up its self-defence martial art system called Brazilian jiu jitsu.
Schools were called academies and teachers were called professors, Lindsay said.
"Some of the language is based on the Portuguese language, which is a Latin-based language."
At the end of the competition Bailey Wills, Philip Jones and Will Macfater emerged as winners in the adult category and Tyler Lubbe, Casey Lubbe and Jenna Fahey were the winners in the junior category.
