Life Flight's Westpac Rescue Helicopter had already scrambled and took over the scene once they arrived.
"Seeing everyone work together was amazing," Lanita recalled.
"It was like clockwork."
Emergency services were at the workplace for about two hours with Jason before he was stable enough to be put into the helicopter and airlifted to the emergency department at Wellington Hospital.
"Everyone was so cool, calm and collected.
"People asked me afterward if I freaked out, but I said I was probably in shock and the fact they were there, and are so amazing, keeps you calm."
Lanita accompanied Jason on the helicopter ride and tried to keep her fear of heights at bay.
In the emergency department, they were met by "a really incredible doctor" before a battery of tests.
After lots of tests, Jason was transferred to the intensive care unit where they stayed overnight.
Some time during the night, Jason was taken off a ventilator because his breathing was better.
