I answered your thread on Hitched Alaina, but it may have got lost in the answers. Have a look at our photos,
www.picturetrail.com/jonathansel we had a grand old time, can highly recommend the southern half of the south island, thats the only bit we visited. Can highly recommend Dunedin, Te Anau, Milford Sound and Queenstown. The Southern Coastal Route is lovely well but take it easy, the roads are only gravel !!!!
