However, it was Brazilian Jiu Jitsu where he found his true passion. With over 30 years of dedication to martial arts, Ricardo Castagna achieved the rank of BJJ Black Belt 2nd Dan.

Ricardo relocated to New Zealand in 2005, arriving as a purple belt in BJJ. Under the mentorship of Pedro Fernandez from Tukaha BJJ, he continued to refine his skills and knowledge. This journey culminated in Ricardo Castagna earning his prestigious black belt in 2017, marking a significant milestone in his martial arts career.

Shin Yi

Shin began his Brazilian Jiu-Jitsu journey in 2014 and earned his purple belt in 2022. He's particularly drawn to the nogi aspect of BJJ, which led him to explore the 10th Planet style and catch wrestling. His catch wrestling foundation came from an old friend, Kevin Hay, who sadly passed away. Open-minded when it comes to the art of grappling, Shin believes every style has valuable techniques worth learning. His philosophy on the mats is simple but effective: pain is your friend, ADD - always do damage, and pain makes your opponent move. 😄

Our classes

Our Gi classes will teach you core jiu jitsu movements, concepts and techniques. These classes will have an additional focus of Gi specific techniques for controlling and submitting opponents.

No Gi

Our No Gi classes will teach you how to use jiu jitsu without the Gi, focusing on the different strategies. The absence of extensive grips results in a more dynamic and fast-paced modality.

Kids and Teens

This program is designed to introduce younger children to the sport of jiu jitsu and for the older children to transition into competition and adult level training. It is great to help children build confidence, body awareness and mental toughness.

Pricing plans

I've been training with Ricardo in Silverdale for roughly two and a half years. He is the best teacher you could possibly hope for. I would and do recommend Ricardo and Black Knights to anyone wanting to start or continue their journey in BJJ.
