Rivers are a significant hazard in the New Zealand outdoors, and you'll come across one on most tramping trips. Rivers are affected by the weather and snow melt, and can rise and fall very quickly. If you're not experienced in river crossings or identifying unsafe rivers, then avoid crossing rivers by selecting tracks that use bridges and always be prepared to change your plans to avoid crossing a river.
Try our new interactive tool:
Many popular tracks have swing bridges or cableways, but not every river is bridged, so trampers often need to cross to carry on along the track.
Unfortunately river crossing deaths occur in New Zealand each year, so you need skill and sound judgement. Take all river crossings seriously. If in doubt, do not cross.
If you’re not experienced in river crossings or identifying unsafe rivers, then avoid crossing rivers by selecting tracks that use bridges. Always be prepared to change your plans to avoid crossing a river. If you’re experienced in river crossings, you can always seek shelter and wait for the river level to drop.
Carefully choose where to cross
The choice of the safest place to cross is vital. Try to view the river from a high bank. You may be able to see gravel spits or sandbanks just below the surface and get some idea of the depth and position of channels. The safest place is one where the river is flat, is no higher than thigh-depth on the shortest person, and has no obstacles in the way.
Use the mutual support method (as shown in the video above). You'll want between 3 and
5 people. The more people in the party, the more strength there is for crossing and for supporting anyone who slips or falls.
As a group, discuss where you will enter and where you will exit. Always choose an exit point which is downstream of the entry, and has no obstacles.
As you cross, travel closely together in a line which is parallel to the current. Keep in constant communication with each other and travel slowly.
We encourage people who are out there alone to not cross rivers by themselves unless they are very experienced. Wait for another party of people to come by, find a bridge or go back.
