Hmm,well I really like Auckland, it has its pluses and minuses though
Pluses :
It's a big city, wel, not in worldwide terms but in NZ tms, so there is, I think, plenty going on socially, culturally - festivals, gigs, free music in parks, free outdoor cinema, kids stuff, swimming pools, theatre, art galleries etc etc. Just look ate site like Eventfinder and compare what's on in Auckland to other cities.
Despite being big, there are loads of quieter, rural ish areas within reach of the city, regional parks, loads and loads of lovely beaches. The Waitakere ranges, west coast beaches, regional parks like Ambury, Scandrett, Mahurangi, loads more, etc etc. all within easy reach of the city.
I think it's more mixed culturally than small NZ towns, there are probably about 20 different nationalities at my dd's primary, which is great.
Weather is generally pretty mild, can rain a lot but also pretty much guaranteed a good summer (ignoring this year!)
Minuses:
Well, it's a big city! Traffic has got considerably worse since I moved here 11 years ago and it will continue to get worse. You can look at living near a train line (only 2 train lines, one goes east then south and one goes west) or look at commuting from the Shore on the dedicated bus lane - driving to the CBD is getting busier and busier all the time. Thoug would your dh be doing unusual hours as if so the commute may not be so bad. we are 20 mins off peak to CBD and it takes dh 30-40 mins if he leaves by 7.30 but could take an hour if he left later. Admittedly that doesn't sound too bad compared to some Uk commutes!
The other big minus is house prices. I'd say getting a house in a decent area for less than 500K is becoming increasingly difficult and for the nicer areas you're looking at more like 700K+. And it won't be a house with any land...it will be a decent sized house with a smallish garden (probably).
Oh bit of an essay, never mind. 90K is doable but tight, depends how much is going on a house. Would be better with another income, even if only part time.
