Ms Bourke said this was the second year for the annual charity fashion event.
"This year's event consists of a drinks and nibbles hour, followed by a fabulous evening of live performances, an auction and fashion shows," she said.
Ms Bourke said the idea behind the show was to bring everybody together in the Tauranga fashion scene to help a common cause.
"We felt the McDonald family has done a lot for the community and, now something terrible has happened to them, so we would like to help them.
"And Elijah has an awful condition, he can't walk, he can't talk, he is strapped into a wheelchair and he can do nothing for himself. He can't even communicate," she said.
Ms Bourke said money raised from the event would go to relieve the financial pressure on the children's parents, who were dedicated to getting their families back on track. More than $13,000 was raised last year for Amanda Lowry, who broke her neck in a surfing accident.
