A Worksafe investigation discovered multiple safety failings at the plant.
The platform the woman fell from had no guard rails or permanent access and didn't meet industry standards.
Although the worker was required to wear a harness there were no rated anchor points for her to attach to.
Worksafe said that the failings were "obvious".
The Government workplace health and safety regulator also found that although Champion had policies and procedures for working at height, they were not effectively implemented.
"A worker now faces a very different life because Champion did not meet its obligations to her," said WorkSafe chief inspector Steve Kelly.
WorkSafe said businesses needed to ensure that plant was safe.
Health and safety policies and procedures would not protect workers unless they were fully and effectively implemented, so engineering controls had to be considered first, he said.
