Johnston was supported by the Halberg Trust and Sport Whanganui, as well as a number of parents and teachers.
Whanganui District Health Board's new disability lead Alex Kemp was also present to see where the DHB could support community-driven initiatives like AccessAbility.
She said the disability lead role was close to her heart because her career as a speech and language therapist involved mainly working with children with complex disabilities.
"Gary is doing some great work, and I was impressed that this is a community-owned and community-led venture," Kemp said.
"Working with people with disabilities is always most successful when it is community developed, led and owned, but the DHB needs to be connected and supportive."
The DHB was preparing a disability strategy, Kemp said, and part of that involved contacting the community for feedback on the document.
"We will be reaching out to organisations we know for input in the near future, but I would encourage anyone interested in providing feedback and input into the strategy – whether an individual or an organisation – to contact me."
