A Hamilton schoolboy has gained selection to represent NZ in karate at the Youth Olympics later this year in Argentina.

Raukawa Jefferies, 17, secured his spot after placing first at the Oceania Karate Champs.

He says he's humbled to represent his Māori heritage. 

"It's a huge honour, I've gotten really strong with my whānau and all my ancestry, representing all that has gone before me and all they've given me."

Jefferies is a two-time Oceania champion and says his parents are behind his success.

"They've done a lot to support me getting through tough times, waking me up in the morning and going to training."

His coach Binh Nguyen says Jefferies has come a long way.  

"He came through my dojo just a little kid.  He's got lots of talent, he trains hard and I see him every day at the dojo."
