Boys injured during Sweeney Todd musical to be released from hospital, tonight's show called off

The two sixteen-year-old boys hurt on stage during an Auckland school's musical last night are likely to be discharged from hospital today.

Saint Kentigern College said this morning it was "distressed" over the incident, which happened during the opening night of Sweeney Todd and left the boys with neck cuts.

The school said tonight's production has been postponed while an investigation into the incident is conducted. 

All students have been offered counselling. Worksafe said it had been told two boys had received neck injuries during the show.

Sweeney Todd tells the story of a barber who kills his clients by slicing their throats, and serves their remains to a nearby mince pie shop.

School's 'priority is to support the boys'

"We are very concerned about the accident at our school last night and we are investigating the causes of this," Steve Cole, Head of College, said in the statement.

"We are pleased that both boys are in a stable condition and have been talking with both their families.

"Our priority is to support the boys and their families, along with the rest of the cast and crew."

"Plays and performances are a big part of all school life. We are distressed about what happened last night and are conducting a thorough investigation."

It tweeted publicity on Tuesday about the show, though it is not clear yet if any of the students pictured above were involved in last night's incident.

Worksafe New Zealand says it is the school's duty to ensure student safety.
