I'm very well aware of the rules in kiwiland as they've been around a long time.
I wouldn't really call less than 2 years "a long time" in the scheme of things. Hell, it's not even 1/10th of the time since i left school!
Bosses sack people anyway - and then find themselves facing criminal charges + larger fines for failing to provide safety training.
The bosses don't provide safety training. They used to, but we now have schemes that
screw over everyone involved "train" people in safety and. No I can't do this. Sorry. It's not in me. These are not schemes they're SCAMS. The safety training I did last year to gain my certification to be able to enter various types of work sites (eg "sitesafe certification for building" or whatever it's called) was a long way below par, and while spending a lot of time on different ways to tie ladders down and how to inspect the certification on scaffolding (not how to safely put up scaffolding, or check it's secure, merely how to look at a label and say that yes the label is there and carries a not-yet-passed date that can be filled in by any one at any time). The thing was an absolute fucking joke, a total waste of time and money, and I would be surprised if any of the younger people who did the course (who don't have real life work experience) are still alive - likely they followed the tutor's advice and suffered a quick and violent death.
One of the advantages of a state-run compulsary accident insurance system is that workers actually do get compensated and dodgy company operators get nailed to the wall.
Not today. Everyone involved gets fined (unless it's something the worker could not reasonably have known about). If I'm testing a power supply and zap myself then I get fined as does my boss for not providing adequate supervision. It could be that my boss told me to leave the thing alone, or it could be that he was telling me to do things in a dangerous manner.
ACC also fines every employer. Every single one - the fines are in the form of "levies". I say they're fines because eg the electrical industry - wiring houses etc. A "home handyman" gets a bit extra crispy because he screws up wiring up an extension lead - the cost of that accident is taken out of the levies that companies, not home owners, pay. And as it's an "electrical accident" then the electricians find their levies going up, even though the person wasn't employed.
But I digress. The laws changed last year when the new health and safety act (2015) came into force (in May IIRC, not the more appropriate April 1st (given some of the act). I haven't read it in detail but from what I do know of it much of it deserves a very large WTF icon to be plastered over the walls of the homes of whoever signed off on it.
