"Those are the memories you don't forget, and those are things that will spark you to carry on and move to another level."
Protagonist (Māori Scythe) from Whanganui High School came second in the solo/duo category and collected the Rockshop Best Use of Electronic Assistance award.
Thirteen bands also hit the stage.
First and second-placed solo-duo acts and the top 12 bands go through to the next stage of the competition - the regional final - which involves submitting a video performance of a second song.
The first song was captured during the regional heats on Thursday.
All bands from Whanganui went through to the regional final.
Covid-19 made it tough for musicians leading up to the event, Common said.
Some acts were forced to drop out while others called in last-minute replacements to fill gaps.
"This year has actually been one of the hardest because of the effect that isolations and stand-down periods had on bands and soloists.
"I feel for those kids. They've been doing the best they can to get prepped and ready to go."
Overall, the night was a great success, Common said.
"I think there were only seven empty seats in the bottom half (of the Opera House) and we almost opened the top level at one stage. That's a great turnout.
"Normally in the heats people come and go but virtually everybody stayed right through until the end. It's a three hour session as well, definitely not a short-haul.
"Students were coming off stage with a real buzz."
