Hey cool
Bit busy here in Jan and the cost of travel and accommodation goes up (its our school summer holidays), but you should get decent weather and will definitely have a great time !
If you're into fishing (or even if you're not yet!), PM me - January is Salmon run season in the South Island, I'll take you down the river and show you how not to catch them
Or just offer some tips on where you can't fail to catch!
