Is there water?
Whether there is a river here on your dates, and what kind of water it is.

Lake-buffered flows, paddleable year-round; commercial season Oct-Apr

Undammed - grade rises sharply after rain; operators ask you to phone 1-2 days ahead to check flow
Grade & who can come
A river changes grade with its level. These grades describe a normal flow - in flood the same run is harder, and often a different run entirely. Check the gauge before you commit.

Rafting and kayaking (Murchison - whitewater capital of NZ)
Grade 3 family day trip vs Grade 3-4 Earthquake half-day vs 3-day expedition. Confirm.
