Why Has Health Insurance Increased So Much in New Zealand?

If you’ve opened your latest health insurance renewal and been shocked by the increase - you’re not alone.

Across New Zealand, many people are seeing premium increases of 15–30%, and in some cases even higher. It’s frustrating, especially if you haven’t made many claims.

So what’s actually going on?

The short answer is this:
Health insurance isn’t necessarily getting more expensive - healthcare itself is.

Let’s break that down in plain English.

1. Healthcare Costs Are Rising Faster Than Everything Else

Most people are familiar with inflation - but what many don’t realise is that medical inflation is much higher than normal inflation.

Right now in New Zealand:

• General inflation is relatively low

• But healthcare costs have risen significantly faster year-on-year

This means insurers are paying more every time a client has:

• Surgery

• Specialist consultations

• Scans and diagnostics

• Cancer treatments

• Prescription medications

👉 Put simply:
The same treatment today costs a lot more than it did just a few years ago.

2. More People Are Actually Using Their Cover

Another major shift post-COVID is how often people are using their health insurance.

There are two key reasons:

• A “catch-up” effect from delayed procedures during lockdowns

• Increased awareness and willingness to seek treatment earlier

The result?
More claims are being made - and more frequently.

And here’s the key insight most people don’t realise:
👉 A large portion of premium increases over time is driven not just by cost increases, but by the fact that people are using their cover more often.

3. Each Claim Now Costs More

It’s not just that there are more claims - each claim is more expensive than it used to be.

Why?

• Specialists are charging more

• Hospitals have higher operating costs

• Diagnostics (like MRIs, CT scans) are used more frequently

• Treatments are more comprehensive

This means insurers are paying out significantly more per policyholder than they used to.

4. Medical Technology Is Improving (But It’s Not Cheap)

Modern healthcare is incredibly advanced - and that’s a good thing.

Today we have:

• Minimally invasive surgery

• Faster, more accurate diagnostics

• Advanced cancer treatments

• New drugs that weren’t available 5–10 years ago

But these improvements come at a cost.

👉 A helpful way to think about it:
You’re not paying for the same “product” you were 10 years ago - you’re paying for a much higher level of medical capability.

5. Pressure on the Public Health System

New Zealand’s public health system continues to face significant pressure:

• Longer wait times

• Increased demand

• Capacity constraints

As a result, more people are turning to private healthcare.

This increased demand pushes up costs in the private system - which flows directly through to insurance premiums.

6. An Ageing Population

New Zealand’s population is ageing, and that has a direct impact on healthcare costs.

Older populations:

• Use more healthcare services

• Have more chronic conditions

• Require more complex treatments

Because health insurance works on pooled risk, this affects pricing across the entire insured population.

So What Does This Mean for You?

While premium increases are frustrating, they reflect a broader reality:

Health insurance is being used more, and the cost of delivering healthcare has increased significantly.

The real question isn’t just “why is it going up?”
It’s:
👉 “Is my cover still structured in the best way for me?”

What You Can Do Next

If your premium has increased, there are options to manage the cost - without losing valuable protection:

• ✅ Review your excess (raising it can reduce premiums)

• ✅ Remove benefits you may not need

• ✅ Consider different plan structures (e.g. surgical-only vs comprehensive)

• ✅ Check your cover still aligns with your current needs

A Final Thought

Health insurance today is no longer something people “might use one day.”

It’s increasingly becoming something people actively use to access timely healthcare.

And while costs are rising, so too is the value - especially in a system where waiting times and access can be uncertain.
