Christchurch, nz
I've been living here for a couple months and I've done the ski to surf 5 times. The wave quality in town here is pretty low now that we are going into spring but during the winter brighton was pretty good. Taylors can produce quality but it can go from head high to a half of crap in the time it takes you to drive out there. You have the banks peninsula with a couple pretty high quality breaks ranging from an hour to more depending how far you get out in the middle of no where. And then there are the great breaks of kaikora which is a little over 2 hrs. Job market here should be good since its a decent sized city and the mountains are 1-1.5 hours with alot of options.
Dunedin,nz
A smaller city but it has much better waves and tons of swell straight out of the roaring forties. If you like bigger waves you will be happy here. The mountains are two hours away and then your in the southern lakes of wanaka and queenstown. Lots of good riding down there.
The trade off of nz is that imho despite the mountains being really sick they are too exposed and snow quality suffers. I wasnt really that stoked on the skiing while I've been here and have just done alot of surfing. Maybe thats the right blend for you.
I've heard good things about italy and ski surf combo days there but I suspect that the surf is poor.
