Studying From Home?
Wantobe
You will only be studying from home if you live in Christchurch - where the training centre is located. And that will only be for the first six months or so.
You will then have to move to a provincial town to do your on the job training - that could be Invercargill or Queenstown (examples of the cheaper and more expensive places to live) and could take up to a year. And then you could be moved to yet another provincial town after you qualify.
When I read your first post I was going to reply and say you needed a lot of cash to start off with - it looks like others have already made that point.
