NZ badly needs a tech scene. It has not produced anything of note like Atlassian in Australia. But the lifestyle is great. Only two time zones from the Australian east coast.
I checked both AUS & NZ and despite the fact I can get in there through the company I work for, it does not seem easy or 'we need all the skilled people we can get'. The process seems not very easy in either country. I will live in AUS probably starting next year to manage the tech side from there and I will definitely check out NZ and maybe skip to there if possible as, for some reason (never been) it attracts me more. That said; I often need to go to China which is easy from AUS; I did not check how it is from NZ.
