Mrs Ball said she will meet longstanding Wairarapa SPCA members ahead of the public meeting, and devise an agenda.
She said it was vital the organisation has " breathing room" to discuss its future.
"The plan is to get the organisation stabilised, and we can worry about what's happening with the centre later," Mrs Ball said.
"That is why I supported the shelter closing - so we can get things functioning behind the scenes."
The meeting will be led by an independent chairperson, and administrators from the national office will attend.
Greytown resident Ashleigh Blake has launched a Facebook group, with the aim of keeping the centre open "by any means possible".
Within "half an hour" of Ms Blake setting up the group more than 200 people had joined. "The more voices speaking up, the better - we need to get the funds rolling in," Ms Blake said.
"I do believe the Wairarapa community can save it".
Ms Blake, who used to volunteer at the centre, said she was "absolutely shocked" to hear of its closure.
"It's just very sad," she said.
"I don't understand - if the finances were that bad, why didn't they reach out for help?"
Ms Blake, who will shortly begin training as an animal welfare inspector, said the shelter's closure will "impact on everyone".
"There will be more animals dumped, fewer rehomed, more neglect - are people going to drive an abandoned animal all the way to Wellington if they find one?
"Not just that, but other services won't be able to cope.
"The pound is only able to deal with roaming dogs, vets are going to be overloaded with de-sexings and injured animals."
