USA Travel Insurance from NZ: Medical Costs and Cover Guide

Why the USA Needs Careful Cover

The USA is one of the destinations where the medical section of a travel insurance policy matters most. If you are treated in a US hospital without insurance, the bill is yours. SafeTravel's general advice applies everywhere: even minor medical treatment overseas can be expensive, and the New Zealand Government will not pay these costs.

That does not mean every policy is the same. Policies differ in their medical limits, how their emergency assistance works, what they exclude and how they treat pre-existing conditions. This guide sets out what to check. It is general information and does not recommend any insurer or policy.

Entry Basics

SafeTravel says New Zealand citizens travelling for tourism or business can enter the US without a visa for up to 90 days under the Visa Waiver Programme. You need a machine-readable passport and an approved ESTA (Electronic System for Travel Authorization). If you are going to study or work, or do not qualify for the programme, you need a visa. SafeTravel also notes that US border authorities apply strict entry rules. (Source: SafeTravel (MFAT) — United States of America travel advice, checked 30 September 2026)

What to Check in a Policy for the USA

Overseas medical limit

Find the maximum the policy pays for medical treatment and any sub-limits (for example on dental or on specific conditions). Some policies describe medical cover as unlimited; read the conditions that apply.

Emergency assistance and hospital payment

Check how the insurer's emergency assistance team works: whether you must contact it before non-emergency treatment, and whether it can arrange payment with a hospital so you are not asked to pay large bills yourself.

Medical evacuation and repatriation

Check whether getting you to a suitable hospital, or home to New Zealand, is covered and whether it needs the insurer's approval first.

Pre-existing medical conditions

Declare every condition the insurer asks about. A claim linked to a condition you did not declare may be declined. See our pre-existing conditions guide.

Destination region

Make sure the destination or region you select on the policy includes the USA, including any stopovers.

Activities and rental cars

Check cover for activities you plan, such as skiing or diving, and whether rental-vehicle excess cover is included or needs to be added.

Natural disasters and known events

Check how the policy treats events that were already known or forecast when you bought it, and read how the wording deals with storms, wildfires and similar events. Buying soon after you book reduces this risk.

Common Mistakes With USA Cover

Not checking the medical limit and sub-limits

Instead: Read the medical section of the policy wording, not only the summary table.

Not knowing the emergency procedure

Instead: Save the insurer's emergency number and understand when you must call it. In a life-threatening emergency, get help first and contact the insurer as soon as you safely can.

Choosing on price without checking US cover

Instead: Compare the medical, evacuation and cancellation sections of each policy side by side.

Not declaring pre-existing conditions

Instead: Answer the health questions fully and keep a copy of what you declared.

Relying on credit-card insurance without reading it

Instead: SafeTravel suggests checking how card cover is activated, whether it has a higher excess, and whether it covers your trip length and activities.

Regional Considerations

Natural hazards differ across the US. SafeTravel's advice for the USA describes the main ones. (Source: SafeTravel (MFAT) — United States of America travel advice, checked 30 September 2026)

Eastern seaboard, Gulf Coast and Hawaii

SafeTravel notes hurricanes regularly affect these areas, especially from around June to November. Check how your policy treats weather disruption and buy cover before a storm is named.

Central Plains and parts of the Midwest

SafeTravel notes tornadoes are most frequent and intense here, with conditions most favourable from March to September.

West Coast, Alaska and Hawaii

SafeTravel lists Alaska, California, Hawaii, Oregon and Washington state among the parts of the US prone to earthquakes.

Remote and national-park areas

Distances to hospitals can be long. Check that the policy covers emergency transport and any activities such as hiking or climbing.

Frequently Asked Questions

Do I need travel insurance for the USA?

SafeTravel, the New Zealand Government's travel advice service, says New Zealanders travelling or living in the United States should have comprehensive travel and medical insurance. It warns that medical costs in the US are extremely high and that the New Zealand Government cannot help with medical expenses.

How much does travel insurance for the USA cost?

It depends on your age, health, trip length, the excess you choose, the activities you add and the level of cover. Insurers price destinations differently, so get quotes for the same dates, destinations and cover level and compare what each policy actually covers, not just the price.

How much medical cover do I need for the USA?

Policies differ: some state an overseas medical limit and some describe medical cover as unlimited, often with conditions. Because US medical costs are extremely high, read the medical and emergency-evacuation sections of the policy wording carefully and check any sub-limits before you buy.

Will my NZ health insurance cover me in the USA?

Do not assume it will. Check your health insurance policy wording for any cover for treatment overseas. If you hold travel insurance through a credit card, SafeTravel suggests checking how it is activated, its excess, and whether it covers your whole trip and planned activities.

Do New Zealanders need a visa for the USA?

SafeTravel says New Zealand citizens travelling for tourism or business can enter the US without a visa for up to 90 days under the Visa Waiver Programme, with a machine-readable passport and an approved ESTA electronic travel authorisation. Other purposes, such as study or work, need a visa. Check current rules before you book.
