"There were at least four opera stars in the rehearsal group, what voices, they were amazing."
The director of the New Zealand School of Music, Euan Murdoch, talked to the students about the rich and diverse legacy of music at the school and encouraged them to look at opera as a possible art form to study.
The workshop also included activities and games that develop group performance and movement, essential components of the genre.
Ms Thurston has won a number of first placings in performing art competitions with her singing and is keen to look at studying opera when she leaves college at the end of the year.
"I love singing and opera is something I've thought about going further with," she said.
"As part of the workshop we had to do a devising piece where we had to create a scene from part two with one of the choruses of the opera. It was really interesting to see what they do with opera and how you can actually go somewhere with it.
"You can manipulate the way your body works when you sing to get the right sound and right strength behind it. You also have to have the right actions and facials to go with it to portray your character in a particular scene," she said.
"It does require a lot of technique and strength. It's not just about the singing - you have to act as well."
