I was thinking to move to Christchurch but you need work permit visa which you can get if you have over 100 points then you are going to pool. Every two weeks they are draw somebody from that pool.
If you manage to get 140+ points you can get visa no question asked, to get that you have to have job offer from Christchurch. Still you will need to get all certificates converted and everything else guys are saying up in their posts.
Not easy at all, if you are going with partner your partner will have to go through same point system.
It is better to organise everything from here, that way it will take much shorter time to finish the process there.
Wish you luck, please let me know how it goes. I am very interested to move there, especially in Christchurch. Electricians are in shortage skilled worker list and it shouldn't be difficult to get job there. Salary as I found online from $30 - $35 /day rent of house around $400/week.
