River crossing safety for New Zealand tracks and camps

Assess before entering

Check the forecast, recent rain and route advice before departure. Look for rising or discoloured water, moving debris, a strong current and no safe exit.

If the river is in flood, wait or turn back. Do not enter to test the depth and never cross merely because another group has started.

Use expertise honestly

River-crossing skills require practical instruction and good group judgement. Unbuckle pack straps where trained guidance recommends it and avoid linking up in ways the group has not practised.

Choose bridges or marked alternatives when available. A longer route is the correct route when the ford is doubtful.

Vehicle fords are hazards too

Know the manufacturer's wading limits and the road authority's closure status. Water can hide washouts and push a vehicle sideways at surprisingly low depth.

Never drive around a flood barrier. Park well back, wait for official reopening and keep enough food and fuel for the delay.

River crossings kill trampers here every year

New Zealand rivers rise fast, run cold and carry more force than they appear to. Drowning during crossings has historically been common enough to be described as the New Zealand death, and almost all of it involves people who decided to cross when they should have waited.

The decision is the skill. Turning back or waiting is always available and always safe; the crossing is not. If there is any doubt, there is no doubt.

Reading whether it is crossable

Look for a wide, straight, shallow reach with an even bed and a safe run-out below rather than rapids, logjams or a deep pool. Discoloured water, debris moving downstream, a rumbling sound of boulders and water above knee height on the shortest party member are all reasons not to cross.

Never cross where you cannot see the bottom, and never immediately above a hazard. Rivers change with every flood, so a crossing point described in an old guide may no longer exist.

If you do cross

Undo the waist belt and chest strap on your pack so it can be shed, keep boots on for grip, and face upstream slightly while moving across and downstream at an angle. Move one foot at a time and keep both feet planted before shifting weight.

Cross as a linked group where possible, with the strongest members on the upstream and downstream ends, and move together. If someone is swept away, they should go feet first on their back and swim for the bank at an angle rather than fighting the current.

Wait it out

Most New Zealand rivers drop as quickly as they rise, frequently within hours of the rain stopping. Carrying an extra day of food turns a dangerous decision into an inconvenient wait, which is why the standard advice is to plan for one.

Tell someone your intentions before you go so an overdue party triggers a response, and carry a personal locator beacon on any route with crossings. Both are cheap compared with the alternative.

Alternatives to crossing

Check whether a bridge exists upstream or downstream before committing, because many tracks have one within a reasonable distance and the detour is almost always shorter than the consequences of getting a crossing wrong.

Many New Zealand backcountry routes are unbridged by design, and the route description usually says whether crossings are expected. Where it does, treat that as a requirement for the skills and the willingness to wait rather than as a passing note.

Waiting is the most underused option available. Most rivers here drop within hours of the rain stopping, and carrying an extra day of food converts a dangerous decision into an inconvenient afternoon.

Learning before you need it

River crossing is a taught skill and reading about it is not the same as having practised. Outdoor clubs, guiding companies and some DOC visitor centres run or can point you towards training, and it is worth doing before a trip with crossings on it.

If nobody in the party has crossed a river before, choose a route that does not require it. There are plenty of excellent multi-day walks in New Zealand with bridged crossings throughout.
