"It was a high standard of music performance.
"Every student had to have achieved NCEA with excellence."
He said Ms Dingwall would have enjoyed the music that was performed.
"There were just acoustic and voice performances with no amplification - no groups or rock'n'roll bands, which is exactly what Sherlie would have wanted.
"They all chose all the songs which have meaning to her.
"[With Ms Dingwall] the kids were learning as opposed to being taught. She [was] very passionate about her whole life.
"She worked with the school for around five years and made a massive impact," Mr Pasco said. "She left a legacy."
Rotorua Hospice chief executive Sharron Black said what the students had done was "lovely".
"I think the lovely thing about this is that it's the youth - they have been touched by this and I think the lovely thing is they set it up and they played pieces or songs that they felt lived up to her memory.
"Things like this, they really help us for our operational levels.
"We need $800,000 in funding every year. It all makes a huge difference," she said.
