After paddling the Arthur River that flows into the Milford Sound you have to paddle across the Sound to get back to the get out. Just make sure you get a boat to take you across to prevent didimo contamination from the Cleddau River.
The Ngakawau River has a beautiful walk in. The put in to the run is marked by the Mangatini Falls. Unfortunately the falls themselves are un-runnable.
Kakapotahi River on the Westcoast of NZ. Amazing upper section to be run with equally amazing scenery.

The Mokihinui is a must for those who have not been there. This photo will not be possible if the Mokihinui dam go's ahead!!
The Lower Buller Gorge is a stunning place and the kayaking in the uper section is great also. (Background image of Photo-Boater blog - Howie Wilson 2009)
