She has posted an update on her Givealittle page and thanked everyone for their support.
The University of Otago student (19) said she'd broken most of her left ribs, cracked her shoulder and had "pretty severe spinal injuries".
She was in Burwood Hospital in Christchurch where she was expected to be for a few more months.
"Still unsure what the outcome will be but we are only hoping for the best. This week has been made a lot easier with all the support from so many generous and caring people.
"I'm overwhelmed by the kind and thoughtful messages, gifts and donations … I would just like to say a big thank you."
Miss Unahi was one of two seriously injured in the balcony collapse that happened at a flat in North Dunedin on Friday, March 4.
A structural engineer investigating for the Dunedin City Council said the collapse, which injured 17 others, was due to overloading.
He said there were lessons to be learned.
He expected to hand his report to the council next week and did not want to speculate on its conclusions.
"I have watched the Animation Research video over and over again and that not only supports the conclusion that it was overloaded, but there were a number of students moving up and down.
"They weren't jumping and they weren't acting irresponsibly but that appears to be the final straw [causing the collapse]."
He emphasised that the behaviour he witnessed on the video was not reckless and the party-goers were dancing, not jumping, on the balcony.
One of the others to be seriously injured was student George Karamaena (18), who was in Dunedin Hospital with two broken legs and a broken back.
His Givealittle page indicated he still needed a couple more surgeries for one of his legs and back.
"George is feeling better but his road to recovery will be long and he still has one more surgery to go."
The student was described as a "cheeky, ambitious, fun-loving young guy that always has a smile no matter the situation".
"He is very passionate about sport, playing rugby, touch and softball."
Any money raised would go towards his recovery and his future ambitions.
