Question for New Zealand Psych Registrars

I'm a UK doctor in New Zealand currently for sabbatical. For a wide range of reasons, my partner (non-medical) and I love it here, and are very strongly thinking we want to move here. I have an offer to train as a psychiatrist in the England, but am thinking of giving it up and applying to psychiatry training here. Can anyone help me with the following:

• how is the training here, and what is the general atmosphere of trainees? Are they happy and content?
• what are the best parts, and the worst parts, of your training experience?
• any advice for someone in my position?

Thanks in advance, any help at all is very gratefully received!
