Trust Rugby International (TRI) is a registered charity, which aims to remove barriers and enable participation for people who may otherwise be prevented from experiencing the joys of rugby.
On Wednesday night, a player breaks a tackle and scores a runaway try. He is met with high fives as he yells "Yes, yes, yes" and makes his way back to the line.
High School Old Boys (HSOB) rugby club runs its TRI training on Wednesdays at North Hagley Park. About 25 players get stuck in.
HSOB Colts Premier player Harry MacDonald is one of the coaches.
"It's one of the more rewarding things I've done," he said.
"The positivity they bring to training every week is what makes me come back."
MacDonald said the players brought different levels of skill, but energy and love for the game was deep across the board.
Although the different levels could be challenging MacDonald said "there are always ways to get around it".
He said tackling practice was a favourite among the players, who loved getting dirty and stuck in.
Linda Healion's son Bradley is in the TRI team and "absolutely loves it", she said.
"It's his highlight for the week."
Healion said the volunteer coaches were great, treating the players with respect.
The TRI team wil play a curtain raiser game for the HSOB premier team on August 22 at 2pm.
