WOW! So many replies, thank you! 
JessM - You know where I live! I'm right at the base of the hill with the Virgin Mary on it. Lots of loos? Really? I know of one set here in P'ram and another in Waikanae by the library and that's it! LOL
Ella46 & Stansgran - Yes, I'm homesick; I need the bluebells in the wood, the Archers, to sit and think in a church; an old church, a church that has the peace of centuries in it. I need blue tits on the bird feeder, a fox trotting down the side of the road. I need a pint, a real pint in a real pub not a sports bar full of drunkards. I need a nice apple; yes, you can find Cox's Orange Pippins here but they're rare but that's it, Bramleys are rare as hen's teeth. 
For those that don't know NZ, I live on the outskirts of Paraparaumu, a small town some 30 miles North of Wellington. I have no family here but do have two sons, both in Lincoln, one of whom is going to be a father in September (Me, a Grand-dad? WOW!) I have a half-sister in, I think, Southampton. No, I couldn't stay with any of them. I have few friends here and even less there.
As for where I'd like to be... gawd knows!
Yes, change is hard with Asperger's; fortunately, the ADHD more than compensates for that. 
The medical system here is fairly good, if you have money! Talking to your GP costs money! You get some of that paid back via the benefit system during the following financial year but you actually have to have the money up front and that can be a significant drain. The available medicines list is restricted here as are the medical devices; the only blood glucose meter available is a Korean thing that is known to give dodgy readings; it is, however, cheap.
I had no idea the benefits system was going to be a problem, housing I did expect trouble with but not benefits. Hell, I paid into the system for nearly 30 years!
Just writing this has given me a bigger clue that I need to come home. The list of "things I miss" put tears in my eyes.
Simon.
