Hopefuls earlier decided which principal or ensemble character they wanted to try out for and stated if they felt their strength was in acting or singing, although both were highly desirable.
They were each given a piece of music and dialogue to learn from the hit show, then had their individual allocated time to shine.A cast of 30 men and women was needed to begin rehearsing next week, leading to the season in the revamped Queenstown Memorial Centre from May 16 to 25.
Mr Aitken said the auditions had been ''exacting and exhausting'' when asked to comment halfway through the process on Saturday night.
''The music has some specific needs in singing, dancing and acting, so it's a long and intensive process.
''Certain characters need triple-threats - people capable of acting, singing and dancing, which in previous plays wasn't so necessary.''
Mr Aitken said the creative team was trimming the list of contenders and he was confident a strong cast would emerge.
