Authentic BJJ Heritage
“I had tried several jiujitsu gyms on trial, but after feeling disappointed, I was ready to give up this amazing exercise. By chance, I discovered this place. It’s like a family and a place brimming with love. I drive here for an hour, and it’s worth it. It’s a place where coaches and team members can exercise while respecting each other.”
- JBrazilian Jiu-Jitsu is more than just a sport, it’s a martial art built on precision, discipline, and lineage. As it becomes more popular worldwide, preserving its authenticity is more important than ever.

About Prof. Hasan
At Grappling-Lab Brazilian Jiu-Jitsu, we’re proud to represent Sid Jacintho Jiu-Jitsu International here in New Zealand.
Our head coach, Professor Hasan Chahoud, is a 3rd-degree black belt under Master Sid Jacintho and brings over 25 years of grappling experience to the mats. Starting his journey back in 2001 at ADCC Abu Dhabi, Hasan trained for over a decade in one of the most elite environments in the world. He began with freestyle wrestling under top coaches like Alexander Savko (“The Bulldozer”), Peter Baltaliyski, and Lubomir Guedjev, before fully diving into Brazilian Jiu-Jitsu.
From there, he trained under a legendary group of Brazilian black masters including Carlos Santos, Suyan Queiroz, Olavo Abreu, Sid Jacintho, Alex Paz, Marcelo Motta, Ricardo Brandao Fraenkel and more, all of them were part of the ADCC coaching team system. This depth of experience shaped Hasan’s style: technical, sharp, and rooted in solid fundamentals.
Hasan moved to New Zealand with his family at the end of 2013 and continued his Brazilian Jiu-Jitsu journey without interruption. In 2015, after 14 years of consistent dedication to the art, he was officially awarded his black belt certificate by Master Sid Jacintho in Abu Dhabi. Although travelling back for the formal ceremony was not possible at the time, Hasan kept training locally in Auckland, teaching, and eventually opened his own academy, Grappling-Lab BJJ, based in Howick, East Auckland.
Today, Grappling-Lab is ranked among the top BJJ teams in New Zealand, with students competing, and winning, at all levels, from kids to adults. But more than the medals, we’re proud of the culture we’ve built: tough, respectful, inclusive, and always hungry to improve.
If you’re looking to start your BJJ journey or take your game to the next level, we’d love to have you on the mats with us.
