"We're definitely looking forward to it," he said.
Mr Setu said the group of opera singers met at the University of Auckland several years ago and have since become great friends.
"It's amazing because it's just nice to share the stage with three of my good friends. It's always a great buzz," he said.
The group have come a long way since their first performance at the University of Auckland's School of Music ball at the end of 2015.
They travelled to Tauranga last November to perform at the Trinity Cathedral and got a "good response" from the audience which was admittedly filled with family and friends, Mr Setu said.
Mr Setu was invited to sing as part of the Lexus Song Quest master class and the Dame Kiri Te Kanawa Foundation. He was also a finalist in the prestigious New Zealand Aria.
The Shades were grateful for the opportunity to travel to the Bay and felt "blessed" to be considered for the performance, Mr Setu said.
With a mix of classical opera songs and music you may just hear on the radio, Mr Setu said there will be something for everyone.
"We cover quite a broad spectrum of songs," he said.
"I think the main objective is to touch someone in the audience and bless them," he said.
The classical concert is an all-ages event and picnics are welcomed. There will be food, wine and beer on offer at concert stalls.
General admission tickets are $65 with an additional booking fee.
