Health insurance premiums rise significantly in your 50s and 60s — but so does the likelihood you’ll need to use it. For many New Zealanders over 50, the question isn’t whether to have health insurance, but whether it still makes financial sense at the higher cost.
The Core Trade-Off After 50
The case for health insurance after 50:
- Greater likelihood of needing elective procedures (joint replacements, cataracts, hernias, cardiac investigations)
- Public wait times are often longest for the conditions that peak in your 50s and 60s
- Ability to choose your own surgeon and timing matters more as your health becomes more complex
- Lower income tolerance for large unexpected medical costs (if you’re reducing work hours)
The case against:
- Premiums are substantially higher — $200–$450/month for a single 60-year-old depending on the plan
- Pre-existing conditions are often excluded — so you may be paying for cover that excludes your most likely health issues
- If you have significant savings and investments, self-insurance becomes more viable
How Premiums Increase With Age
Stepped premiums (the most common structure in NZ) increase annually. For a $500 excess hospital plan:
| Age | Approximate monthly premium (single) |
|---|---|
| 50 | $170–$270 |
| 55 | $230–$360 |
| 60 | $300–$450 |
| 65 | $380–$580 |
| 70 | $480–$720+ |
These are indicative. Premiums vary significantly by insurer and plan.
At age 70+, premiums can become difficult to sustain. Some people reduce cover (e.g. dropping dental/optical or choosing a higher excess) to keep premiums manageable.
Pre-Existing Conditions — The Critical Issue After 50
If you’re buying health insurance for the first time after 50, the pre-existing condition problem is significant. Any condition you’ve been diagnosed with, treated for, or had symptoms of before taking out the policy will be excluded.
Common exclusions for people in their 50s:
- Cardiovascular conditions
- Diabetes
- Musculoskeletal conditions (back problems, joint issues)
- High blood pressure
- Mental health history
If these conditions are excluded, you may find you’re paying high premiums for a policy that won’t cover your most likely claims.
This is the strongest argument for buying health insurance before conditions develop — ideally in your 30s or 40s when you’re in good health and can get broad cover at low cost.
Is It Worth Buying Health Insurance After 50 for the First Time?
If you’re in good health with no significant pre-existing conditions
Yes, it’s generally still worth buying health insurance. You’ll pay more than you would have in your 30s, but you’re still getting broad cover before major health events develop. Conditions that develop after the policy starts are covered.
If you have multiple pre-existing conditions
Be realistic about what will actually be covered. Get a list of exclusions in writing before committing. If the conditions most relevant to your health are excluded, the policy may provide less value than it appears.
If you have significant wealth and liquid assets ($500k+)
Self-insurance becomes more viable. You could direct the premium money toward investments and use your savings for medical costs when needed. This requires discipline and acceptance that healthcare costs can be unpredictable.
Strategies for Over-50s
Choose a higher excess
A $2,000–$4,000 excess reduces premiums significantly. This effectively means you’re self-insuring for routine costs and using insurance for major events — a sensible approach if you have savings to cover the excess.
Downgrade from comprehensive to surgical cover
If you’re finding premiums for a comprehensive plan unaffordable, switching to a surgical-only plan reduces costs while retaining the most important protection.
Review your sum insured and optional extras
Remove benefits you’re unlikely to claim (e.g. dental if your dental health is good, optical if you already wear glasses and have routine check-ups covered via Medicare or routine costs).
Lock in before retirement
If you’re planning to retire in your 60s and expect reduced income, buying or upgrading health insurance while you’re still earning is easier — both because you can afford it and because more health issues may be insurable now than after retirement.
Health Insurance at 65+ and NZ Super
From age 65, New Zealanders receive NZ Super regardless of health status. NZ Super provides a base income but doesn’t cover private medical costs. Health insurance continues to make sense for many retirees — but the premium-to-value calculation requires careful assessment.
Providers don’t currently cap the age at which you can hold a policy, but some increase excess requirements or reduce maximum benefits at higher ages.
