Louisa Kuypers was taken to Auckland City Hospital in a critical condition after falling from the roof of a Lion Breweries building in Newmarket about 2.30pm on Friday.
Her condition has since improved to stable, although she remains in hospital with injuries including a broken back, ribs, ankle, collarbone, deep bruising and a punctured lung.
Initial CT scans indicated Ms Kuypers had not suffered brain injuries, and medical experts have labelled her survival "extraordinary".
Her father Gilbert Kuypers spent yesterday morning at the hospital and said because of pain medication his daughter was drowsy.
"She remembered that she just fell off, and it was just a quick drop, and she only remembers the weightlessness feeling of it, and that was the end of it. She just went blank after that." Ms Kuypers' colleague had just completed an abseil drop and when she got over the side of the building and put her weight on the equipment "the whole lot let go".
He said only a couple of weeks ago his daughter had to be rescued after a piece of her gear malfunctioned and she became stuck mid-abseil. Since then, she had used new equipment, so Mr Kuypers felt the fall was unlikely to have been caused by a gear malfunction.
A witness said a metal anchor which attached Ms Kuypers to the building fell to the ground with her.
The Department of Labour is investigating with the assistance of Ms Kuypers' employers At Height, who could not be reached for comment yesterday.
St John medical director Tony Smith said Ms Kuypers' survival "in terms of the height she fell was extraordinary".
