Karate New Zealand is expecting a spike in membership and exponents switching from other martial arts codes after the sports inclusion in the next Olympics.
"I would expect that we may get some new students join that are looking for the Olympic dream, and see some clubs change from the fundamentals," said Karate NZ head coach Duane Monk.
"Getting into the olympics should raise the level and we may have athletes from other codes, such as tae kwon do, trying their hand at karate for the opportunity to make the team."
Karate will feature as an Olympic sport in Tokyo 2020 for the first time, along with surfing, skateboarding and sport climbing.
Monk said there had been a rise in interest in Karate since New Zealand's record Olympic haul in Rio, and more parents are pushing their children to take up the sport competitively.
