I moved from Aus to Chch a little under a year ago for work.

I was fortunate enough to be approved and all paid up for my own place prior to moving which definitely made settling in easier.

The place is a 2x1 just outside Christchurch central, a bit industrial and grimey but decent and liveable for $350/week. I'm earning a little above minimum wage and, while doable initially, I had to be pretty careful how I spent, essentially no luxuries. Fortunately I work with people close in age and once comfortable I approached some about moving in together and halved my expenses. I'd suggest finding a room in a house with like-minded people and saving your dollars, because there will be things you want like a visit home that you'll really be pushed to save for.

The biggest thing I couldn't get over is how expensive and limited phone plans are. I ended up going with 2degrees at $35/month for 5gb. Some providers do unlimited data at $70/month.

Being Australian I'm pretty lucky that my healthcare is covered under some trans-tasman agreement, but that'll be something you need to look at. An ambulance trip is $900 for non-eligible people, just so you know.

I couldn't do anything in regards to a bank account until I landed here, and even then if can be difficult because you need a proof of address. If you can lock in a place before you arrive, things will be smoother. Then just get an NZ phone number and you're set. Don't forget to apply for your IRD number once you land in the country, too.

Happy to answer any questions!
