Hunt said people could rock through the event with their children before heading on to the Redwoods Children Day.
Money raised will go towards maintenance and care of the ponies, and buying new ponies to help with the demand for the service.
She said there were currently 60 to 70 children who rode with them, from around the region including Murupara and Opotiki.
"It's really busy and the demand is such that we had to start a wait list."
It also caters for groups, including primary schools, along with Kea Street Specialist School and 'Stand' children's health camp.
Hunt said it was an all-weather venue and encouraged people to go along, see the horses and see what it had to offer.
"I just think it's a great way for locals to come out and support a worthwhile charity."
She said the organisation did not get any government funding and she thought a lot of people did not understand it was not just a pony ride.
A physiotherapist came every week and helped the children on the horses, she said.
"There is proven science behind what we do for the client's overall wellbeing."
Co-organiser La Grouw said the event was about awareness and fundraising.
She said it was a great charity to support because of the therapy it gave to a lot of children.
La Grouw said the children may have a disability which was a teaching deterrent or a physical disability, and their association with animals was amazing - "we all know animals are healing".
