Otonga Road School Year 6 student Samantha Conrad, 10, said it was her first time doing J Rock and she was excited.
"I feel it's going to be really good, but there will be competition."
There had been a lot of preparing and cleaning up of dances leading up to the performance, Samantha said.
She said one of the best parts so far had been getting to dance with all her friends.
"We are all like a big family."
Samantha said their school's performance was about bullying.
The teacher in charge thought it would be a good theme to portray because Otonga Road School was a bully-free school, Samantha said.
The school's co-ordinator, Kirsten Laurence, said the process had been long but the students had all been committed.
"They've been practising this term, pretty much every day."
