Three parents of children with special needs also spoke about their experiences.
"It was very good to hear from our parents who are living it day in and day out," she said. "It made it more real."
Mackintosh told the Bay of Plenty Times the school would have to cough up more than $118,000 to fund a shortfall and said the ministry was "very much aware" of the school's funding difficulties.
She said they discussed additional funding towards increasing support for teacher aids as part of the Budget 2018 announcement but "we are not sure what that is going to look like".
At the meeting, Mackintosh said the school had proposed to set up a pilot scheme for 2-3 years and had scheduled another meeting at the school to go through details with the head of learning support on June 7.
"It is about inclusive education. We are an authentic and inclusive school," she said.
Parent Erika Harvey was also encouraged by the meeting and was happy the ministry got to meet the children personally.
Harvey's 7-year-old daughter Piper is autistic and is a pupil at Greerton Village School.
"No one ever meets these children. When I applied for funding for Piper no one came to meet her," she said.
"It was all done on a piece of paper. I had to relive the darkest hour of the darkest day just so she has more opportunity with her education."
Harvey said a video she made exploring the funding challenges helped to shine a light on the issue and had so far been viewed by more than 20,000 people.
"It is really driving awareness," she said.
Harvey hoped the ministry would consider more funding for Ongoing Resourcing Scheme (ORS) children at the school and nationwide.
"For every parent who doesn't get adequate funding for their child we have to think about leaving our fulltime jobs," she said. "Every child deserves an equitable education."
Ministry of Education deputy secretary of enablement and support Katrina Casey said the ministry would continue discussions with the school to look at ways of supporting an inclusive approach to education.
"We are working with the school to better understand their finances and identify options to address their concerns," she said.
