Overlooking Wanaka from the 553m peak was a feat for the 28-year-old, who has lived with a spinal cord injury since she was 19.
"We weren’t quite sure if it would be possible for me to get up there, but it shows with the right people anything is possible."
The team of five began the ascent at 7.30am on November 17, and were back down again by 9am.
Her team of four assisted her, adding tension to the ropes strapped to a harness so she wouldn’t gather up too much speed on the descent.
She says there were a few "scary" sections where the track was rocky, but through teamwork, they were able to manoeuver around them.
Ms Unahi has undertaken a number of physical challenges in the past few years.
She participated in the Wings for Life World Run in Auckland this year, and is training for a spot to represent New Zealand at the Winter Paralympics 2026.
She says the Mt Iron challenge came about after talking with friends about giving the Millennium Track a go.
After that success, they turned to Mt Iron.
Ms Unahi said she was glad to have gone up.
"It was nice to see Wanaka from a new perspective — that 360-degree panoramic view of Wanaka, and no assistance of helicopters to get there ... it was very rewarding."
There have been jokes about taking on Roy’s Peak before Ms Unahi, a winter-chaser, heads to Europe for another ski season.
