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.

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.

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. 😄

Home away from home. These guys are like family. If you're interested in martial arts, self defence and fitness then I highly recommend Black Knights! You'll be hard pressed to find a more welcoming team. Oss!

A great school and training experience. Ricardo and the other instructors are highly skilled and classes cater for all levels. The whole crew welcome new students into the Black nights family no matter what level you are at. Highly recommend this school.

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.
