Honest about the risks, and specific about what prevents each one.
Adventure activities
The Government of Canada states plainly that serious accidents have occurred in New Zealand and that tour operators may not always meet international standards, advising travellers to hire an experienced guide from a reputable company. This is the risk that sends Canadians to hospital there โ not an infection.
Prevention Check your travel insurance covers the activity BY NAME โ bungee, heli-skiing, canyoning and jet boating are commonly excluded. Ask the operator about their safety record and their emergency plan before you pay.
Sun and UV
CDC lists sun exposure among the risks for New Zealand. Burn times are short, and cloud is not protection.
Prevention Broad-spectrum SPF 30+ reapplied every two hours, a hat, and cover up in the middle of the day. Bring your medication list to the appointment โ several common prescriptions increase how fast you burn, and we will tell you which of yours do.
Driving
The Government of Canada calls road conditions and safety very good, but notes roads can be narrow, winding and hilly. New Zealanders drive on the left, and the combination of a jet-lagged Canadian, a rented campervan and a one-lane bridge is a genuine hazard.
Prevention Do not drive the day you land. Build far more time into each leg than the map suggests โ an hour on a New Zealand road is not an hour on Deerfoot Trail.
Leptospirosis
CDC names it: a bacterial infection picked up from water or soil contaminated by animal urine. Relevant to farm stays, caving, river swimming and long tramps after rain.
Prevention Cover cuts before going into fresh water, and mention any fever after a trip involving rivers or farms to your doctor โ including that you were in New Zealand.
Cold and exposure
CDC lists cold-weather injuries. Alpine weather changes fast in both islands, and the Tongariro and Routeburn crossings catch people out in summer clothing.
Prevention Layers, a windproof shell and a plan for turning back. The same rules as the Rockies, on a mountain range you do not know.
Earthquakes, cyclones and a volcano
The Government of Canada notes earthquakes and tsunamis occur, that cyclones usually run November to April, and that Mount Ruapehu in Tongariro National Park is at alert level 2 for volcanic gas emissions.
Prevention Nothing to take. If you have asthma, keep your reliever with you on the Tongariro Alpine Crossing and check the alert level the morning you go.
