If you come to the South Island of New Zealand, please don't fly from Christchurch to Queenstown — drive!
The drive is absolutely beautiful, and along the way, this is one of the stops. The Clay Cliffs take a little bit of a drive (30 mins out of the way from Omarama), but they are really worth it. There is just a short hike to get this view, and you can even get up in there and walk around inside. It's enchanting, and you may recognize these from a few scenes in LOTR.
When you take the little hike, you can bring a wide-angle lens and maybe something a little tighter, and you'll be set and ready to go!
