Andrew McKerrow, a Salvation Army chaplain for the racing industry, officiated the service and said the scene he saw was "something I won't forget for a long time".
He said it was moving to see the community's support for Black's family.
The chaplain got to know Black through his chaplaincy work and had supported the horsewoman through some of her own personal struggles.
McKerrow said he admired her tenacity and ability to pick herself back up from hard-times.
"She was going through a rough patch, she wasn't getting as many rides, so she went out and found this pony school and was working to develop it," he said. "She was an inspiration because she didn't want to leave all her eggs in one basket."
McKerrow said it was "pretty tough" remembering how happy she seemed about her future when he last saw her a fortnight ago.
"She said I feel like I'm getting back on my feet," he said. "I'll miss bumping into her at the races."
Deputy chief executive of New Zealand Thoroughbred Racing [NZTR] Campbell Moncur, described it as a very moving service.
"Everyone is upset, it's one of those things that you always hope won't happen," he said. "It's so tragic when it does."
He said a collection from those who attended brought in some $15,000 which would go towards a trust for her three children, Bassy, Caleb and Lilly.
Moncur said the Jockeys Association had also pledged $5,000 towards the trust, while jockeys hitting the tracks in the coming weeks could also choose to donate, all or part, of their riding fees to the family.
He said the logistics of setting up the trusts and appoint trustees were still being ironed out, but support was all starting to "roll in".
Moncur said the association would continue to support the family as needed.
At the funeral, fellow rider Terry Moseley, who also fell from his horse spoke on behalf of the New Zealand Jockeys Association described Black as a loving mother and a "very versatile horsewoman".
He highlighted her achievements including taking note of her 108 race wins. Moseley also paid tribute to how she'd made a "very special effort" to attend the funeral of the only other jockey to die at a race in the last decade - Ashlee Mundy.
Mundy died on December 31 2012, after a fall the previous day at Kurow.
Another South Island jockey, Samantha Wynne, recalled her close friendship with Black.
She described the mum as a passionate horsewoman with a bubbly personality who would leave a massive hole in the jockey's room.
A number of investigations into the incident would be held; by the stipendiairy stewards that were at the Tapanui Racing Club meeting on Sunday; a police report was going to the coroner, followed by the coroners' inquiry and a WorkSafe NZ check .
