Ashlynn's disorder has resulted in frequent visits to both Palmerston North and Starship Hospital. In 2012 Ashlynn spent nine months in hospital struggling with repeated infections and a collapsed lung.
Despite this battle, Ms Ralston said her daughter had a remarkable inner strength and patience.
"She is very strong-minded and she doesn't let things get her down."
Manfeild Park chief executive Heather Verry said the venue was delighted to lend their support with a show that has attracted everything from your beloved family runabout to your extreme performance vehicles.
"We applaud the initiative shown to provide support for Ashylnn and hope that the community responds with kindness," she said.
