Hi
Just to add my 2c worth again
I have no problem with boy racers drink driving is (I guess) a big problem lots of rural drinking and bad roads, the roadside is littered with crosses
I know not all are drunk.
However driving is seriously bad we were nearly run off the road by a massive lorry whilst driving around still having palpitations about it and the nutters driving at 100 literally 6 inches from my bumper (OK it's 100k not miles but still) someone mashed our car in a car park (whilst I was sitting in it!) so at least they couldn't deny it they did try though 
Drugs will depend on area
Just before we came we lived very short term in a basement flat and the broadband was a bad as you imagine I wanted to throw the computer on the floor every night here it's the same (and we're reasonabally elevated) however my UK dongle (£15) used to drop all credit after 1 month so that's a plus. However my 2 degree phone seems to drop it's credit.
IMHO and IMHE the health service is not better I think whoever said it was is just out of date re the UK I'm sure I've posted about my recent experience with stitches as just one example, you need to remember you'll be paying around $30 every time you take an over 6 to the Docs (I believe vacs are free but some GPs do try to charge)
re the Brit thing I hear more Brits here than in my part of S London! 
Seriously though this is all so dependant on where you are, where I am the sections are tiny (mind you same for my family in Nelson) and there are very few school pools (that is unusual for NZ though) I like this thread since it reminds me that it is all so personal and so different IYSWIM
I suspect the universals are that
the driving is bad
you are more likely to live in a lower quality home here
it is more expensive (although I've long thought that we don't pay the price we should for things in the UK)
you have to pay for Docs visits (not under 6)
some groups have big drug probs
you are more likely to have a bigger garden (outside of some town homes)
the meat is good and cheap
milk products good (except cheese)
produce is seasonal
your 'average' school is probably better than an 'average' UK city school (I know nothing about very rural schools)
property is cheap (compared to London!
)
what do others think?
(oh I didn't go to Tauranga sorry is it still on the cards?
PS I think your Mum has been reading this thread
