The singers will be accompanied by a jazz band led by Richard Anaru.
Mrs Hulton said 180 people could fit in the church and they wanted as many people as possible to attend.
The last fundraising concert, which was Matariki @ St Faith's, was a huge success, and was classical and musical theatre, she said.
"The last one went really well, it was mostly all full."
People should go along to support the fundraiser because St Faith's was an icon of Rotorua, Mrs Hulton said.
The music was also great and there were some great local performers, she said.
After the concert, people would also have the chance to mingle with the musicians.
"It's just going to be a really fun afternoon."
