That was then. Now a couple are defunct as the gangs in town have claimed a chunk of the membership.
But there are about 25 kids at training tonight with their dads or relatives in tow.
They're put through a series of warm-up drills from Karauria as he works them through cones, ladders, flags and posts he has set up around the field. He has purchased all the gear out of his forestry earnings.
Several parents praise his devotion while lamenting the lack of sports gear available in schools.
Karauria watches his pride then whistles them into a huddle.
"Pain is my favourite word," he tells them. A few start to shuffle and look a little worried until he stares one boy down with a warming line.
"You are Keven Mealamu's double," he says.
The boy's face lights up like the national grid and his dad glows too.
They start to talk about their next game and who's going to play in what positions. Tuso doesn't think he can make it because he has to go to church.
No matter says Karauria, as long as kids make it to practice and have a good time.
