Because this 2019 School marks the 25th year of the school a spectacular concert on the river is planned for Thursday, January 17 starting at 7.30pm.
A pontoon will be constructed during the day on Thursday and will provide the stage with a walkway from the Waimarie building on to the Riverboat Waimarie.
The 21 opera students will fill the decks of the river boat while specialised soloists including Sol3Mio, (Samoan brothers Pene and Amitai and their cousin Moses) and video screen live appearances of other well known alumni including Simon O'Neill and Bianca Andrews.
A waka will come up river from Putiki to open the concert and draw alongside the Waimarie.
