If in doubt, stay out.
Rivers are a living feature of the New Zealand outdoors. Their banks and gorges provide some natural access-ways to our mountainous areas so it is vital to respect them and understand why they are a potential hazard on your adventures.
There are about 180,000km of rivers in New Zealand, so you will likely meet one on your journey in the outdoors.
Some popular tracks have swing bridges or cableways, but trampers often need to cross rivers. 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.
14% of fatalities in selected outdoor activities are from crossing a river.– There and Back, 2016
If you see a bridge is out or there is flooding turn back. Tell other people in the area and the local DOC office when you return.
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. If you’re experienced in river crossings, you can always seek shelter and wait for the river level to drop.
Warning signs of an unsafe river
Prepare your clothing, gear and footware before crossing to try keep some items dry and make yourself more balanced.
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.
Use mutual support methods. The more people in the party, the more strength there is for crossing and for supporting anyone who slips or falls. All river-crossing methods have their advantages and disadvantages and, in difficult conditions, no method is absolutely safe.
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.
Make sure you warm up with a hot drink, fresh dry clothes or a blanket after your crossing.
New Zealand generally has many areas with safe drinking water, especially in the backcountry away from dense populated areas. It is important to have water with you at all times and therefore to fill up your bottle wherever possible. If you are unsure about the quality in a certain water source, boil it or use a water filter before consuming. For more information visit our cooking and fires page.
Take extra care to make sure everyone in your group is comfortable with your planned route, especially if it includes river crossings.
