A 35-strong faculty from New Zealand, Australia, England, the United States and the Netherlands was handpicked to suit this year's focus on Inhabiting the Text.
It was a theme that flowed through the curriculum, there would also be a strong emphasis on English diction and Italian language.
"We are striving to give students insight on how to bring a piece of music alive," Ms Tobin said.
"This takes an understanding of the composer, the lyrics, and the significance of the piece within the opera or musical. Researching and reflecting on all these elements, gives a richer performance."
The school was unique in that it covered both music theatre and classical musical genres, seen as being very important for a productive career.
New Zealand baritone, Robert Tucker returned to the school as Artist in Residence, providing a useful insight for students.
He followed the footsteps of broadway music theatre star Liz Callaway and Napier-born lyric soprano Anna Leese.
"We are excited to have Robert with us, [he] has settled back in New Zealand, although he continues to perform internationally.
"Very importantly, he is an alumni of the school and will relate well to the students."
