Speights Ale House for a bloody good feed and fresh beers, Dux de Lux in Christchurch and Queenstown.
As suggested before Milford Sound which is fantastic,Mackenzie lakes with Mount Cook in the back ground is speccy.
In Queenstown take the cable car ride to the top of the mount the views are well worth it,you do mini Bungey jumps in a chair ,para glide to the bottom or as I did have a go on the Luge, hadn't had so much fun in years and that was on the begginers run.
Wanaka war birds museum if your lucky they might be flying,I watch the P51 Mustang fire up and take off...fark me it sounded like a hundred Harley's roaring down the highway.
The Cardronna pub is in the area iirc, and the " pantie fence " for a laugh,if it's still there.
