NZJSBA Rule Book


Due to IJSBA not formally releasing the official 2017 rule book and inconsistencies around IJSBA posted amendments the NZJSBA will be running the 2017/18 closed course season under the 2016 IJSBA rule book incorporating any supplementary rules/regulations posted on official NZJSBA sites.  It is a riders responsibility to ensure they are aware of all rules/regulations before competing. Clarification can be sought by contacting the NZJSBA office.


NOTE: If you have any queries regarding the rule book or supplementary regulations then you must contact the NZJSBA Tech Director first before modifying your craft.
