Higgins was left $300,000 out of pocket from the event. He was seeking $2m from Ramsay and his company Gordon Ramsay Holdings, plus celebrity agents Kruger Cowne.
The Chance To Eat Trust was in line to make $200,000.
Higgins said he would only settle the court action with Ramsay if there was a payment in it for Matisse: "This court action is meant to put things right."
The chef was promised around $100,000 for two nights work, plus first-class air fares, and all expenses paid.
Big corporate sponsors also contributed significant amounts. TVNZ supplied $200,000 in airtime in return for access to Ramsay. A TVNZ spokeswoman said this was part of a wider sponsorship deal with Duco, and the network did not pay for interviews.
"We are not out of pocket," she said.
Whitcoulls donated $140,000, while the New Zealand Herald - sister paper to the Herald on Sunday - also invested thousands of dollars in the event.
The huge sums were news to Jodee Reid, the devoted mum who has moved her family to Pittsburgh, in the US, so 11-year-old Matisse can be close to a specialist unit.
As a small business owner, Reid sympathised with Duco and said she was disappointed with Ramsay.
"David Higgins had put in so much. A lot of people lost a lot."
Matisse, meanwhile, is discovering a taste for unusual foods - her favourite meal was squid, which she cooks in breadcrumbs, pan-fried or skewered.
"She likes to buy it unfilleted and cut out the eyes," says Jodee. "She hates McDonald's and refuses to eat junk food."
Ramsay, who flies to New Zealand next month for a promotional trip, claimed his mother's illness prevented him from appearing at the first charity dinners in April 2010. The event was rescheduled for October that year but Ramsay cancelled again.
The court documents show Ramsay had more family troubles, firing his father-in-law and business mentor Chris Hutcheson, who had run his global restaurant empire for more than a decade.
Hutcheson and Ramsay both went on to sue each other, with the case recently being settled.
