Staying healthy in New Zealand

Who pays if you are ill or hurt

The UK has a reciprocal healthcare agreement with New Zealand, but it is narrower than many visitors assume. GOV.UK says British nationals who live in the UK, on a short visit, can get urgent healthcare; it does not extend to routine treatment or prescriptions. Health New Zealand’s own description is that a UK citizen ordinarily resident in the UK is treated as a New Zealander would be, when a doctor decides prompt attention is needed and the condition began, or became acutely worse, after arrival. The provider decides whether you qualify; we found no list of the documents they ask for, so carry your passport. If you are not a UK citizen, or have lived away from the UK for some time, do not assume the agreement covers you.

ACC is New Zealand’s own answer to accidents. It covers anyone injured in an accident in New Zealand, visitors included: a fall on a track, a cycling crash, a sprain on a ski field. It pays for the injury-related part of your treatment while you are in the country. In return, as ACC puts it, visitors give up the right to sue in New Zealand. ACC does not cover illness, disrupted travel plans, the journey home, or treatment once you have left; and providers may charge their usual part-charge, which ACC suggests you discuss first.

So insurance still matters. GOV.UK advises cover for treatment and for unexpected medical evacuation. Health New Zealand says neither reciprocal agreement gives full cover, and ACC tells visitors to insure for everything it does not pay for. Neither scheme will fly you home.

Before you go: vaccinations and medicines

No vaccinations are required to enter New Zealand. GOV.UK asks travellers to check TravelHealthPro at least 8 weeks before they go, for routine recommendations and anything specific to them. Measles has been circulating. Health New Zealand reported two Auckland cases linked to overseas travel in February 2026, after a national warning in late 2025, and advised two doses of MMR before travel. We could not find the position in October 2026, so check that both your doses are done and look for a current notice before you fly.

The outdoor risks at a glance

Most of what a visitor needs to watch in New Zealand is outdoors. Each is explained below.

Sandflies

New Zealand’s sandflies are the visitor’s most memorable nuisance, and only a nuisance. They are tiny black flies, and only the females bite. According to New Zealand Geographic, they are at their worst in Fiordland and on the West Coast of the South Island, at the edges of forest beside streams and rivers, and on beaches; they are active when the air is humid, which in Fiordland is most of the time, and hungriest around dawn. The bites swell and itch for days. None of New Zealand’s species carries a disease that affects people; Te Ara, the government’s encyclopedia, says the same. The risk is the scratching, which can let in an infection.

What helps is cover rather than cure. Long sleeves and trousers, light-coloured clothing (New Zealand Geographic reports that dark colours attract them more), and a strong repellent, applied before you get out of the car rather than after. We found no official advice on which repellent works best, and the feature notes that the strongest products have their own drawbacks, so read the label.

The sun

The sun is the risk most British visitors underestimate. Health New Zealand describes New Zealand’s ultraviolet levels as very high. It advises staying out of the sun, or protected, between 10am and 4pm from September to April, and at any time the UV index is 3 or above. Its advice is the familiar list, taken more seriously: SPF 30+ broad-spectrum, water-resistant sunscreen, put on 20 minutes before you go out and reapplied every 2 hours; a hat; sunglasses; and clothing that covers you. It is the UV that burns, not the heat, so a cool, breezy day on the water or on a ridge is no protection.

Water: huts, streams and towns

Treat water from streams, lakes and hut tanks before you drink it. The Mountain Safety Council says all water from natural sources and hut tanks should be treated, because clear water can still carry giardia, cryptosporidium and other bugs, and there is no simple test on the spot. Boiling is the most reliable method: at least a minute, or 3 minutes above 2,000 metres; filters and tablets vary. The Department of Conservation has 686 huts and campsites exempt from the drinking-water rules, and manages them with signs telling visitors to boil the water; its hut and campsite pages say whether the water is treated.

In towns, we found no official statement for visitors on tap water, so we will not make one. Public supplies are regulated, and councils issue a boil-water notice when there is a problem; if you see one, follow it.

Beaches and hot pools

Swim between the flags. Water Safety New Zealand says rips cause more beach rescues than anything else, and some of the country’s most beautiful beaches have the strongest surf. Swim between the red and yellow flags, where lifeguards are on patrol; unpatrolled beaches are a common factor in drownings. If a rip carries you out, stay calm, raise a hand, and float or swim across the current, not against it. Its own advice is plain: if in doubt, do not go in.

Getting help

In an emergency, call 111. For advice, Healthline on 0800 611 116 is free and open 24 hours; GOV.UK lists it, though we could not confirm that it serves visitors in every case. To find a GP or an urgent-care clinic, GOV.UK points to Healthpoint. As a visitor you cannot enrol with a practice, so you will be seen as a casual patient and pay at the time. If your phone is old, check it can call 111 at all: our guide to staying connected explains why.
