New Zealand – Health Issues

What are the most common health issues and diseases in New Zealand?

The greatest share of New Zealand’s health burden stems from non-communicable diseases (NCDs). The Government Policy Statement on Health 2024–2027 sets out a framework for tackling five such conditions — cancer, cardiovascular disease, respiratory disease, diabetes, and poor mental health — which together account for around 80% of deaths and a substantial proportion of all health loss in the country.

Cancer sits at the top of the list as the leading cause of death. Although improvements in early diagnosis and treatment have lifted survival rates, significant disparities in both incidence and outcomes persist. In 2022, 28,275 new cancer cases were registered in New Zealand, which amounts to approximately 77 diagnoses every single day. Among men, prostate cancer, colorectal cancer, and melanoma are especially common, with melanoma rates notably elevated because of New Zealand’s intense UV environment.

Ischaemic heart disease — the most prevalent form of cardiovascular disease — is the second most common cause of death. In 2022 it was responsible for 4,602 deaths, corresponding to an age-standardised rate of 42.2 per 100,000 people. Stroke is another major cardiovascular concern, with high blood pressure recognised as one of its primary drivers.

Beyond cancer and heart disease, New Zealand’s principal health challenges include mental health conditions (including suicide), diabetes, musculoskeletal disorders, dementia, injuries, and oral health problems. Gout is also strikingly prevalent: as of 2024/25, roughly one in 20 adults (4.8%) had received a gout diagnosis, with rates considerably higher in men (7.9%) than in women (1.9%).

Respiratory conditions affect a substantial portion of the population. As of 2024/25, around one in 10 children aged 2–14 years (10.9%) had asthma requiring treatment. Asthma and COPD are particularly common in more disadvantaged communities. People living in rural areas often face additional hurdles when trying to access healthcare, and the resulting gaps in service can make managing chronic conditions more difficult outside major cities.

Data from the 2021 Global Burden of Disease study indicates that 85% of all health loss in New Zealand — measured across both death and disability — is attributable to non-communicable diseases. This underscores just how central lifestyle factors such as diet, physical activity, tobacco use, and alcohol consumption are to the country’s public health agenda.

Is New Zealand considered a healthy country? How do health outcomes compare internationally?

By most international measures, New Zealand performs well on health outcomes. That said, considerable disparities exist within the country, with people in highly deprived areas and Māori and Pacific communities experiencing shorter lives and a disproportionate share of illness.

New Zealand’s overall life expectancy at birth in 2022 was 82.8 years — above Australia (83.2 years), European Union countries (80.8 years), and the OECD average (79.6 years), and well above the global average of 71.9 years. For cohorts born in 2022–2024, projections show life expectancy reaching 80.3 years for males and 83.7 years for females, placing New Zealand in a strong position alongside Australia and much of Western Europe.

However, the picture is far from uniform across the population. A clear gradient exists between the most and least socioeconomically deprived neighbourhoods: people in the most disadvantaged areas can expect to live approximately a decade fewer years than those in the wealthiest communities.

Ethnic differences are equally stark. Māori males have the lowest life expectancy of any group at 73.4 years, while Pacific males live to an average of 75.4 years. Māori and Pacific women also have lower life expectancy than the national average, at 77.1 and 79.0 years respectively. Closing these gaps is a stated commitment of the New Zealand government.

Public sentiment about the health system reflects some tension between overall confidence and concerns about capacity. Three-quarters of New Zealanders (76%) feel the system is overstretched, and 62% point to understaffing as the core problem — both well above the 31-country global average. Despite this, 49% of those surveyed rated the healthcare system as very good or good, which exceeds the global average of 44%. Expats from countries with universal public systems alongside supplementary private insurance — such as Australia or France — may find the structure broadly familiar. For the most current data, consult the WHO New Zealand country profile and Stats NZ.

What infectious diseases or environmental health risks should expats be aware of in New Zealand?

New Zealand does not carry the tropical infectious disease burden common to many parts of Asia, Africa, or the Pacific. Malaria, dengue fever, and yellow fever are absent from the country. Strict biosecurity controls at the border, combined with the country’s island geography, have prevented many diseases from ever gaining a foothold. Nevertheless, certain risks are worth understanding before you arrive.

Seasonal influenza circulates every winter — between June and August in the Southern Hemisphere — and respiratory illnesses including COVID-19 remain present in the community. New Zealand’s National Immunisation Schedule provides free vaccinations against a broad range of diseases, including measles, mumps, rubella, hepatitis B, and tetanus, for eligible residents. Expats should confirm their immunisation history is complete both before departure and once settled in the country. The New Zealand Immunisation Schedule is available online, and your home country’s travel health authority can advise on any pre-departure requirements.

Among the most significant environmental health risks in New Zealand is ultraviolet (UV) radiation. Because New Zealand lies at a latitude where the ozone layer is thinner than over much of the Northern Hemisphere, UV levels can reach extreme intensities — especially during summer (December to February). Health authorities estimate that roughly 30–50% of cancers could potentially be prevented by reducing exposure to known risk factors, with excessive UV exposure among the most important. Melanoma rates here rank among the world’s highest, and authorities strongly recommend wearing SPF 50+ sunscreen daily, covering up with protective clothing, and staying out of direct sun during peak UV hours — generally 10am to 4pm in summer.

Urban tap water is safe to drink across most of the country, with local authorities responsible for treatment and ongoing monitoring. In rural and backcountry settings, however, giardia — a waterborne parasite — can contaminate rivers and streams, making untreated natural water unsafe to consume. Air quality in New Zealand’s cities is generally good, though some southern regions that rely on wood-burning fires for winter heating can see elevated particulate matter levels during cold months.

Leptospirosis, a bacterial infection contracted through contact with infected animals or contaminated water and soil, is present in New Zealand and poses a particular risk to those working in farming or spending significant time in rural settings. Meningococcal disease also occurs and vaccination is recommended for certain groups. For the most current guidance on disease alerts and vaccination advice, consult the Ministry of Health NZ and your home country’s public health authority before travelling or relocating.

Is smoking common in New Zealand, and what are the laws around it?

Over many years, New Zealand has worked steadily toward becoming a smoke-free society. Smoking inside enclosed public spaces, workplaces, restaurants, bars, and on public transport has long been banned under the Smoke-free Environments Act 1990 and its subsequent amendments. Arriving expats will find that, as in Australia, Ireland, and most of Western Europe, indoor smoking in hospitality venues is simply not something they will encounter.

In December 2022, New Zealand introduced what was widely regarded as some of the world’s most ambitious tobacco control legislation, designed to push smoking prevalence below 5% across all population groups by 2025. The measures involved reducing nicotine content in cigarettes, drastically cutting the number of outlets permitted to sell tobacco, and establishing a generational ban on smoked products. Despite strong backing from health researchers and clinicians, the incoming sixth National-led coalition government reversed this legislation on 27 February 2024.

The impact of that reversal is already visible in the data. Daily smoking prevalence stayed essentially flat between 2022/23 and 2024/25, hovering between 6.8% and 6.9%, in sharp contrast to the steady year-on-year declines recorded between 2011/12 and 2022/23. Smoking rates remain markedly unequal across population groups: as of 2024/25, daily smoking was most common among Māori (15.0%), Pacific peoples (10.3%), and adults in the most deprived neighbourhoods (12.9%).

When vaping is included alongside smoking, the overall daily prevalence of tobacco and vaping combined reached 17.1% of adults in 2024/25, rising from 14.5% in 2019/20 — a trend largely driven by increased vaping. Daily vaping rates were highest among Māori (27.5%), Pacific peoples (20.0%), young adults aged 18–24 (23.0%) and 25–34 (20.5%), and those in the most deprived neighbourhoods (21.1%). Regulations covering vaping in public spaces broadly mirror those applying to cigarettes in many contexts, though this is an evolving area of policy — check the Ministry of Health NZ for current rules.

Broader public attitudes toward smoking in New Zealand are distinctly negative, and lighting up outdoors in family-friendly or crowded public areas may attract disapproving looks. Tobacco products have been sold in plain packaging with prominent graphic health warnings since 2018.

Is obesity or poor diet a significant health concern in New Zealand?

Obesity is one of New Zealand’s most pressing and persistent public health challenges. In 2024/25, one in three adults (34.2%) were classified as obese — up from 31.3% in 2019/20. This places New Zealand near the top of the OECD for adult obesity, at broadly similar levels to Australia and well above most European nations. The gap between socioeconomic groups is stark: around half of adults (46.8%) living in the most deprived neighbourhoods were classified as obese, compared with just over a quarter (27.6%) in the least deprived areas.

Child obesity is another area of significant concern. In 2024/25, 11.7% of children aged 2–14 years were classified as obese. School-based and community-level initiatives have been introduced to improve nutrition and physical activity levels among younger New Zealanders. In a 2024 survey, cancer (38%) and obesity (30%) were ranked second and third among New Zealanders’ biggest health worries, with concern about obesity having risen markedly from the previous year.

Traditionally, New Zealand’s diet has leant heavily on meat, dairy, and highly processed convenience foods, though shifting demographics and growing urbanisation are changing eating patterns. Fresh produce can be expensive, particularly in regional and rural areas, and food affordability is widely acknowledged as a contributing factor to diet-related health inequity. Government health policy explicitly targets poor nutrition as one of five modifiable risk factors — alongside tobacco use, physical inactivity, alcohol consumption, and adverse social conditions.

Expats from countries with distinct food traditions may notice a strong presence of international fast-food chains and processed products alongside high-quality local produce. Farmers’ markets thrive in towns and cities across the country, and New Zealand’s agricultural and horticultural sectors make fresh, locally grown food genuinely accessible. The country’s outdoor culture — centred on tramping (hiking), cycling, and water sports — offers excellent natural support for an active lifestyle, which many residents enthusiastically embrace.

What are the mental health attitudes and services like in New Zealand?

Mental health has become the single most prominent public health preoccupation in New Zealand. For the second consecutive year, it was identified as the country’s top health concern in national surveys, with more than half of New Zealanders (59%) naming it their biggest worry as of 2024. New Zealand now ranks among the top five countries globally where mental health is viewed as the foremost health problem.

The scale of need is reflected in population data. In 2024/25, one in seven adults (14.3%) reported experiencing high or very high levels of psychological distress in the four weeks prior to the survey — nearly double the 7.4% recorded in 2019/20. Rates of distress are especially pronounced among disabled adults (35.5%), young people aged 15–24 (22.9%), Pacific peoples (23.8%), Māori (22.5%), and those living in the most deprived communities (21.4%). These figures reflect both a genuine rise in need and, in part, a growing willingness to acknowledge and discuss mental health openly.

Culturally, New Zealand has made meaningful progress in reducing the stigma around mental ill-health. Public campaigns have normalised help-seeking, and this shift is especially evident among younger generations. In practice, however, accessing services can be challenging. As in Canada or Australia, publicly funded mental health services in New Zealand are most readily available for people with moderate-to-severe conditions; those with milder presentations often find few options through public pathways, and waiting times for non-urgent psychological support can be substantial.

The usual entry point into public mental health support is your General Practitioner (GP), who can refer you to community mental health teams, counselling services, or specialist secondary care if required. Subsidised therapy options exist through certain providers, and the national free mental health line — 1737 (call or text) — is staffed by trained counsellors around the clock. In cities, private psychologists and therapists are plentiful, though out-of-pocket costs can be considerable without insurance. Many health insurance policies available in New Zealand cover mental health treatment to some degree, making it a key factor to consider when comparing plans as an expat.

The Government Policy Statement on Health 2024–2027 outlines the Minister for Mental Health’s priorities across mental health, addiction, and suicide prevention, which are woven through the broader health system strategy. Funding for mental health services has grown in recent years, though demand continues to exceed capacity across many parts of the country.

Are there any health risks specific to expats living in New Zealand?

While New Zealand does not carry the exotic disease risks associated with tropical destinations, relocating here brings a range of health-related adjustments that are worth anticipating. Understanding these before you arrive puts you in a much better position to look after your wellbeing from day one.

• UV radiation and skin cancer: This is probably the most underestimated hazard for people moving from higher-latitude countries. New Zealand’s UV index regularly hits extreme levels during summer, and sunburn can occur rapidly — even on overcast days. Melanoma is one of the country’s leading cancer concerns, and health authorities advise building a consistent sun-safety routine from the moment you arrive, including daily SPF 50+ sunscreen application.
• Mental health and isolation: The stress of relocation, physical separation from close family and friends, and the effort required for cultural adjustment can all fuel anxiety and depression. Expats are just as vulnerable to the population-wide mental health pressures described above, and New Zealand’s geographic remoteness — especially for those relocating from nearby continents — can sharpen feelings of homesickness and disconnection.
• Access to primary care: As of 2024, 73% of New Zealanders agreed that GP appointment waiting times are too long. Registering with a GP immediately after arrival is essential, particularly because in some regions — especially rural ones — GP practices have limited capacity for new patient enrolments and waiting lists can stretch for months.
• Altitude and outdoor hazards: Those who explore New Zealand’s mountain ranges — particularly in the South Island — face genuine risks from altitude sickness, sudden weather changes, and cold exposure. Thorough preparation and safety planning are non-negotiable for any backcountry adventure.
• Dietary transition: Moving between very different dietary patterns — for instance, from a diet rich in fresh vegetables and pulses to one that is more meat-heavy or processed, or vice versa — can produce digestive and nutritional adjustment. Early consultation with a GP or registered dietitian is easily arranged through the public health system and can smooth the transition considerably.

On arriving in New Zealand, expats should make several practical health moves: enrol with a local GP without delay; confirm that all immunisations are current; arrange suitable health insurance coverage, particularly if full public subsidies do not yet apply to you; book relevant health screenings such as a skin check; and note the address of your nearest hospital emergency department along with the national telephone health advice service, Healthline (0800 611 116).

Where can expats find reliable health information and services in New Zealand?

New Zealand offers a well-developed network of authoritative health information resources, and expats are encouraged to go directly to these official sources, since guidelines, fees, and eligibility criteria are subject to change.

• Ministry of Health NZ (Manatū Hauora): The central government source for public health policy, the national immunisation schedule, mental health service information, and population health statistics. Annual results from the New Zealand Health Survey are published here.
• Health New Zealand – Te Whatu Ora: The national body responsible for organising and delivering health services. The website provides regional service locators, patient information resources, and data publications.
• Health Navigator New Zealand: A reliable, plain-language health information website covering conditions, medications, and services. Particularly useful for expats who are new to the New Zealand health system and want clear, accessible guidance.
• Stats NZ – Health: New Zealand’s national statistics agency, providing regularly updated population health data on life expectancy, mortality, disability, and related topics.
• WHO New Zealand Country Profile: The World Health Organization’s country overview, allowing New Zealand’s health indicators to be benchmarked against international standards.
• Healthline (0800 611 116): A free, 24-hour telephone service where registered nurses provide health advice. An invaluable resource for expats who have not yet registered with a GP or who need guidance outside standard clinic hours.
• 1737 Mental Health Helpline: A free call-or-text service available around the clock, staffed by trained counsellors. Open to everyone in New Zealand, regardless of residency status.

Information about fees, entitlements to subsidised care, vaccination requirements, and clinical guidelines is updated periodically. Always verify the latest details through official New Zealand sources and, where applicable, through your home country’s travel health authority before and after your move. Speaking with a GP or an international health insurance provider as part of your pre-departure planning is also strongly recommended.

Frequently Asked Questions About Health Issues in New Zealand

Do I need any vaccinations before moving to New Zealand?

New Zealand does not require proof of vaccination as a condition of entry for most visa categories, but it is strongly advisable to ensure your routine immunisations are fully up to date before you travel. Key vaccines to check include those for measles, mumps, rubella, tetanus, hepatitis B, and influenza. Review the New Zealand Immunisation Schedule on the Ministry of Health website and seek pre-departure advice from your home country’s travel health authority.

Is the tap water safe to drink in New Zealand?

In the vast majority of towns and cities, tap water is treated and regularly tested by local authorities, making it safe to drink straight from the tap. Quality can vary in a small number of remote rural communities. Importantly, if you are spending time hiking or travelling through backcountry areas, you should never drink directly from rivers or streams, as these can harbour giardia and other pathogens.

How does New Zealand’s obesity rate compare internationally?

As of 2024/25, 34.2% of adults in New Zealand — roughly one in three — are classified as obese, placing the country near the upper end of the OECD range. This is broadly comparable to Australia and considerably higher than obesity rates across most of Europe. Addressing obesity is a priority within national health policy, with targeted programmes focused on improving nutrition and physical activity, particularly among children.

What is the biggest mental health risk for expats in New Zealand?

The most frequently cited mental health challenges among expats relate to isolation, the psychological demands of relocation, and separation from established support networks. New Zealand’s physical remoteness can heighten homesickness. Across the general population, reported psychological distress has almost doubled — from 7.4% to 14.3% — between 2019/20 and 2024/25, so there is strong public and institutional awareness of mental health needs. Support is available through GPs, the free 1737 helpline (24/7), and private mental health practitioners.

Is skin cancer a real risk in New Zealand?

Very much so. New Zealand has one of the highest melanoma incidence rates in the world, driven by intense UV radiation resulting from a thinner ozone layer over the Southern Hemisphere. While fair-skinned people face the greatest individual risk, UV exposure is a concern for people of all skin types. Health authorities recommend applying SPF 50+ sunscreen every day, wearing protective clothing, and limiting time outdoors during peak UV hours — typically 10am to 4pm in summer. Routine skin checks with a GP or dermatologist are strongly encouraged.

Are mental health services in New Zealand accessible to expats?

Eligibility for publicly funded mental health care depends on your visa or residency status. Most people lawfully residing in New Zealand can access basic public mental health services via a GP referral. The 1737 helpline — available free by call or text, 24 hours a day — can be used by anyone in New Zealand regardless of immigration status. Private therapists and psychologists are widely available in cities, and many expats choose to supplement public services with private health insurance that includes a mental health component.

What should I do if I get sick soon after arriving in New Zealand?

Make enrolling with a General Practitioner (GP) a priority from the very start — do not postpone this until you actually feel unwell. For urgent but non-emergency health concerns, call Healthline free of charge on 0800 611 116, which is available 24 hours a day. In a genuine emergency, call 111. If you have not yet enrolled with a GP, most medical centres can see you as a walk-in or casual patient, though costs will typically be higher. Visit the Ministry of Health or Health New Zealand websites to confirm what publicly subsidised care you are entitled to.

Does New Zealand have any unusual infectious diseases I should know about?

Malaria, dengue fever, and yellow fever do not occur in New Zealand. However, leptospirosis — a bacterial illness transmitted through contact with infected animals or contaminated water and soil — is present and of particular relevance to those working on farms or in rural environments. Giardia poses a risk in untreated backcountry water sources. Meningococcal disease occurs and vaccination is recommended for some groups. Seasonal influenza circulates each winter between June and August. Always check the Ministry of Health for current disease alerts and vaccination recommendations.
