Trust secretary Cassey Thompson said music was therapy and that's why they had chosen that format for the event.
She said it was an important cause given statistics released this week showed Lakes DHB suicide figures had reached the highest number since 2010/2011.
"It's as common as the flu.
"We want to try to reduce the stigma and make people talk about it."
The trust, whose other members were Camilia Ransfield, Tiria Kiel-Vercoe, Anahera Waaka-Stockman and Wahia Walker-Poroa, planned to hold more events for the cause throughout the year and was already planning Christmas in the Wai for November 30.
"As long as there's a statistic we'll keep going," Kiel-Vercoe said.
"Because of the kaupapa there are people that will support it.
"There won't be a person tomorrow that has not been affected in some way.
"Whether it's whānau or extended whānau we're trying to raise awareness that there are people who are not professionals but are there to help."
Ransfield encouraged people to attend the event to spend quality time with family.
The trust hoped to make the event an annual occurrence.
