The pupils won the Sheilah Winn Award for their performance of Shakespeare's Othello, and year 12 pupil Reva Grills also won the Outstanding Performer Award for her role as Emilia.
The cast also won awards for best voice projection and most courteous and co-operative cast backstage.
And to top it off, year 13 pupil Luke Major won the Outstanding Student Directed Design/Costume Award for his interpretation of Love's Labour's Lost.
About 30 pupils from the school were involved in the performances.
Head of drama Sarah Spicer said it was the first time the school had won the top award, and it was the best Sheilah Winn awards haul in the school's history.
''We're really proud. We're tired after five days in Wellington, but we're absolutely over the moon.''
The school was highly praised by Globe Theatre founding education director Patrick Spottiswoode for its bilingual presentation, she said.
''Because we performed Othello in Maori and English, it was really praised by Patrick Spottiswoode, as being really thought-provoking and something that really inspired him ... so that was very high praise indeed from him.''
Pupils from around the country will be selected next week to attend a Shakespeare workshop in Wellington, where 25 pupils will be selected to go to the Globe Theatre in London, she said.
