⚡Key Field Takeaways
- ✓New Zealand uses the International River Grading System from Grade I (easy) to Grade VI (extreme & unrunnable).
- ✓The Kaituna River near Rotorua features Tutea Falls (7 metres), the worlds highest commercially rafted waterfall.
- ✓Always dress for cold alpine water temperatures: thermal polypropylene, full 3mm-5mm neoprene wetsuits or drysuits are mandatory.
- ✓River strainers (fallen beech trees and willows) are the leading cause of paddle entrapments in New Zealand.
- ✓Check flow gauges on Riverable before launching; high water transforms gentle Grade II runs into raging Grade IV torrents.
International Whitewater Scale in New Zealand #
- ✦ Grade I (Moving Water): Gentle flow with regular small ripples. No obstacles; basic steering required.
- ✦ Grade II (Easy): Clear passages with wide channels and small waves. Suitable for novice kayakers and packrafters.
- ✦ Grade III (Medium): Irregular waves, rocks, and narrow passages. Requires good maneuvering skills and knowledge of eddy turns.
- ✦ Grade IV (Difficult): Powerful, turbulent water, constricted gorge chutes, unavoidable stoppers, and demanding scoutable rapids.
- ✦ Grade V (Extremely Difficult): Violent, congested rapids with high consequence drops, complex lines, and dangerous hydraulics. Examples: Buller Gorge, Shotover Skippers Canyon, Rangitata Gorge.
- ✦ Grade VI (Commercial Limit / Extreme): Unrunnable or runnable only under exceptional circumstances by elite teams with dedicated safety backup.
