Nestoj, congratulations on the job offer!

Whereabouts in the country are you moving to? Housing and living costs vary considerably, depending upon where in New Zealand you live - Auckland, Wellington, Christchurch and Queenstown are the most expensive places. It can be hard finding good rentals in Christchurch, due to housing shortages resulting from the earthquakes two years ago. I think the economy is starting to look up slightly, but don't know anything about the software industry.
Let me know if there is any specific information you'd like about NZ. I can also help with local Orthodox Church and Christian contacts.
Congrats again. New Zealand is a wonderful country and I'm sure you'll enjoy living here.
Deborah
