No, I wouldn't say as expensive. But it does have a buoyant housing market still, whereas London is still depressed.
I've just moved back to NZ after 12 years in London. We're living in Mt Albert renting a 3 bed villa, beautifully decorated, in the Gladstone (highly desirable) primary zone and in zone for Mt Albert Grammar. It's $600 per week. We are a family of three, with a 3.5 DS
Our other costs:
Food - I would say closer to $1000 per month, including lunches at cafes, coffees, etc.
Petrol - 200 - I don't know, I don't drive a huge amount, probably spend less than this but I mostly do short jaunts once a day.
elec/gas. 400 - only in winter, when you will be paying most for your heating. We have an arrangement where we pay $50 a week, which doesn't cover the bill in the winter but will no doubt pay it off over the summer.
I have no idea of the following.....
Health Insurance - we don't have this yet. But a drs appt for under 6 should be free. A drs appt for adult can range between $15-45 depending on practice and your funding.
Life Insurance - haven't got it yet. Next on the list.
Car Insurance - mm, can't find it. Sorry, but we combine car and contents and it's not very expensive.
Broadband/home phone - I have a high broadband account because I work from home and need to download heavy files. So we pay rental of $100 per month, this includes unlimited national toll calls and we use skype for international.
Mobiles - I have an iPhone my plan is $35 per month and I haven't run out of texts, data or calls yet.
TV to get the BBC? - you'll probably want to buy a freeview box at least but it's a one-off purchase (unless you decide to subscribe to Sky).
Public transport I think it quite reasonable - look at the [[http://www.maxx.co.nz/ maxx website to see whether it would be helpful in the areas you are thinking about. My DH doesn't drive, we live 3 mins walk from a train station that takes him to his job in the CBD.
DS is in childcare 2 days a week, with the fee (using the 20 hours ECE allowance) at $22 a day.
If your DH is going to be driving to Hamilton regularly it might be worth looking at areas with quick access to SH20. We do this drive often as my parents are in Hamilton and it reduces the time and traffic a lot. I like Mt Albert A LOT - come and live here and I'll meet you for coffee
