Ricardo Castagna
Ricardo Castagna, originally from Sao Paulo, Brazil, began his martial arts journey at a young age, starting with Judo and later Hapki Do.

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.

Our classes
Gi
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.
