Key Takeaways
Switching health insurance providers in NZ can save money or get you cover that better fits your life, but the move can also cost you cover for conditions that arose under your current policy. Before you switch, check exactly what you would keep and what you would lose. This guide walks through the risks, what to compare and how to switch without leaving a gap.
- A new insurer will usually assess your health again and may exclude conditions your current policy covers.
- New policies often have waiting periods before some benefits apply, even if you held cover elsewhere.
- Compare policy wording, benefit limits and the excess, not just the premium.
- Under current New Zealand law you must disclose everything material when you apply to a new insurer.
- Reducing extras or raising your excess can lower costs without the risk of new exclusions.
- Do not cancel your existing policy until the new one is confirmed in writing and you are happy with the terms.
Why people switch health insurance providers
Most people start thinking about switching when a renewal notice arrives with a higher premium. Others want different benefits or a policy that better suits a new stage of life.
Premiums rise with age
Health insurance premiums generally increase as you get older, and medical costs also tend to rise over time. A quote from another insurer that looks cheaper can be tempting, especially for couples or families paying for several people.
Other common reasons
- Wanting benefits your current policy does not include, or higher limits for surgery, specialists or tests.
- Service issues, such as slow claims or difficulty getting prior approval.
- Life changes, such as having children, children leaving home, or leaving a workplace scheme.
- Paying for extras you no longer use.
All of these are valid reasons to review your cover. The key is to understand the trade-offs before acting.
The hidden cost: losing cover for existing conditions
The biggest risk when switching is not price. The risk is losing cover for the treatment you are most likely to need.
How a new insurer assesses you
When you apply to a new insurer, the insurer usually assesses your health history from scratch. Any condition that developed while you were covered by your current policy may now be treated as pre-existing and excluded from the new policy. Your current insurer may be covering that condition today, while a new insurer could exclude the condition permanently or for a long stand-down period. Our guide to health insurance and pre-existing conditions in NZ explains how insurers treat your history.
Waiting periods may start again
New policies often include waiting periods before some benefits can be claimed, such as for non-accident conditions or specific treatments. These usually apply from the start date of the new policy, regardless of how long you were insured elsewhere. Ask exactly which waiting periods apply and how long each one lasts.
Switching offers and transfer terms
Insurers sometimes offer special terms to attract people switching from another provider, such as waiving some waiting periods. These offers can be useful, but the conditions vary and may not include cover for existing conditions. Read the terms carefully and get them confirmed in writing.
What to compare before you switch
A fair comparison looks at the whole policy. Use these checks as a starting point.
| Check | Question to ask | Why the check matters |
|---|---|---|
| Exclusions | Will the new insurer exclude anything my current policy covers? | Losing cover for an existing condition can outweigh any premium saving |
| Waiting periods | Which benefits have waiting periods, and for how long? | You may be without cover for some treatment in the early months |
| Benefit limits | Are the limits for surgery, specialists and tests similar or better? | Lower limits can leave you paying more if you claim |
| Excess | How much is the excess, and does the excess apply per claim or per year? | A cheaper premium may come with a higher excess |
| Premium over time | How is the premium likely to change as I get older? | A low starting premium is not the full picture |
| Claims process | Is prior approval needed, and how are providers paid? | A smoother process matters when you are unwell |
Read the policy wording, not just the summary
Marketing summaries and comparison tables can hide important differences. Definitions, exclusions and limits are set out in the policy wording, and two policies with similar headlines can treat the same claim differently. If you are comparing several options, an adviser can line up the wording side by side.
Disclosure when you apply to a new insurer
Applying to a new insurer means answering health questions again, and the same disclosure rules apply as when you first took out cover.
What the law requires today
Under current New Zealand law, you must tell the insurer any information that would influence a prudent insurer's decision about whether to offer cover and on what terms, even if the application form does not specifically ask. If something material is left off, a future claim could be declined or the new policy could be cancelled.
Changes coming in 2027
The Contracts of Insurance Act 2024 will replace this with a duty for consumers to take reasonable care not to make a misrepresentation, mainly by answering the insurer's questions carefully and honestly. According to MBIE, those changes are due to take effect on 15 November 2027. Until then, the current duty applies to any new policy you take out.
Alternatives to switching
Before you move, see whether you can reduce the cost of your current policy while keeping the cover you have built up. Sorted also suggests looking at how you pay and how much cover you really need.
- Raise your excess. Our guide on how to choose your health insurance excess explains the trade-off.
- Remove day-to-day extras you rarely use, such as dental or optical.
- Review optional benefits for specialists and tests.
- Ask whether paying annually or by direct debit reduces your premium.
- Check whether your current insurer offers other policy options you could move to without new underwriting.
Changes within your existing policy that reduce cover usually do not require new health questions, so they avoid the main risk of switching. Increasing cover later may involve underwriting, so think carefully before removing benefits you may want back.
How to switch health insurance safely
If switching still makes sense after comparing your options, follow a careful process.
- Gather your current policy documents, including any exclusions and your policy start date.
- Apply to the new insurer and answer every health question fully and accurately.
- Wait for written acceptance terms, including any exclusions and waiting periods.
- Compare the acceptance terms with your current cover, line by line.
- Agree a start date for the new policy, and only then arrange to cancel the old one from the same date.
- Update direct debits and keep copies of all correspondence.
Never leave a gap
Keep your existing policy in place until the new policy is confirmed in writing and active. A gap in cover can leave you exposed to large bills and means anything that comes up in the meantime is likely to be excluded later.
Check for a free-look period
Some policies include a short period after the start date when you can cancel and get a refund of premiums if you change your mind. Check whether the new policy has one and how long the period lasts, and use the time to read your documents.
How SHARE - The Advisory can help
An adviser can compare your current policy with alternatives, explain what you would gain and lose, and help you decide whether switching is worth the risk. If staying put is the better option, we can look at ways to make your current cover more affordable.

Conclusion
A cheaper premium is only a saving if your cover comes with you. Compare exclusions, waiting periods, limits and wording before you switch, look at ways to reduce your current premium first, and never cancel until the new policy is in place.
For some people, switching is the right move. For others, adjusting an existing policy protects more value. This article is general information only and is not personalised advice.
Frequently Asked Questions

Many new policies have waiting periods for some benefits, which usually start from the new policy's start date. Some insurers offer switching terms that waive certain waiting periods, so ask.
Is it better to switch or reduce my current cover?
