"I started teaching myself when I was 13 and was the only girl entering competitions."
She said people telling her she couldn't compete only motivated her more to succeed.
Since then she has competed throughout the world, appeared in a VICKS commercial and has shared the stage with some of the biggest names in music such as George Clinton, Michael Franti, Cold Chisel and The Wailers.
"We need to get the message out there that it's not okay to bully.
"It could really ruin someone's life," Haami said.
Bully Free Bro co-ordinator Warren Tumarae said it was great to have strong role models like Haami sharing her story.
"A friend of mine tagged me on Facebook in a video clip of hers and I messaged asking if she would like to come to Rotorua and become an ambassador of the Bully Free Bro," he said.
"It's about engaging with the kids to spread the message and they really like the whole beatbox thing."
Haami also spread the Bully Free Bro message at the Rotorua Youth Centre last night which was organised by Crash Palace Creative Arts Trust which aimed to uplift and empower children through music and art.
