Pros
There are some amazing people who work at KiwiRail - They're the ones who make you want to stay. But they are heavily relied upon to make heroic efforts to keep the place running. The one thing that do take truly seriously in employee physical safety.
Cons
This place is like jumping on a timewarp and going back to the 70's - And they like it like that. Do not expect to see progression in any way, shape, or form. Expect to see managers do things to stroke their own egos including making some seriously bad decisions for the company. Like getting rid of most of their female managers. It has been noticed. The fact they are being relied upon to help meet the country's carbon goals is a joke. That would mean people would have to look at improving and not just relying on one or two employees to save the company's butt when things go wrong - because they often do.
