The Midnight Youth lead singer and SFRQ alumni, Jeremy Redmore, gave the aspiring musicians advice on the music industry.
He told the crowd that aspiring professional musicians had to be prepared to do it for the love of music, nothing else.
"Don't get into it for fame or money," said Redmore. "If you want to be famous, go on a reality TV show; it is way easier."
SFRQ is now in its 25th year.
About 700 entries are expected to go through regional heats and finals in 23 towns from Invercargill to Whangarei.
Founder and director Glenn Common says while much has changed in the 25 years that SFRQ has been running, there are some things that remain the same.
"The enthusiasm of young people for their music, and the way they respond to having a platform to perform to their peers is one of the constants," he says.
"These days they can put their video clips up on YouTube, but that hasn't taken the thrill out of getting up on stage in front of a live crowd."
