Guide to Health Insurance

Health insurance buying tips

Don't set and forget

Health insurance isn't a set-and-forget expense. Your needs change, and so do policies. Take half an hour at least once a year to review your cover. A quick review can help you cut out what you don’t need and ensure you’re covered where it matters.

Consider a higher excess

A higher excess means you'll pay more out of pocket if you need treatment, but it can significantly reduce your premiums. If you're fit, healthy, and not making frequent claims, this could be a way to reduce the cost of your premiums. Just ensure you've enough savings to cover the excess if you ever need to use your policy.

Loyalty won't always save you money

Health insurers love long-term customers, but that doesn’t mean they'll reward you for sticking around. If you've been with the same provider for years, chances are you're paying more than you need to. Before your policy renews, shop around, compare policies, and see if switching could save you money. And don't be afraid to call your insurer and ask for a better deal. You might be surprised at what they offer to keep you.


What are the benefits of private health cover?

More than 1.4 million New Zealanders have private health insurance, according to the Health Funds Association of New Zealand.

Health insurance can allow you to skip lengthy public hospital waiting lists, and give you peace of mind that your loved ones will be covered should they need to go to hospital.

Private health insurance can offer you the freedom to choose your doctor and hospital, and stay in a private room – if one is available. It can make waiting times for elective procedures shorter than in the public hospital system.

Extras cover can help you cover the costs of services not covered by the public system, such as dental, optical and physiotherapy. Private health insurance can also offer additional benefits you might not necessarily be aware of, like gym membership discounts and access to fertility support. 


What are the different types of private health cover?

Health insurance policies vary between providers. However, most policies fall into one of three categories:

Everyday/regular

  • An affordable option that provides assistance for everyday health expenses, such as visits to doctors and dentists, or optometry and physiotherapy costs.

Specialists & private hospital treatments

  • More comprehensive covers that provides payments for specialist visits, diagnostics and surgery/treatments in private hospitals.

Cancer drug/non-PHARMAC-funded medication

  • Provides access to expensive and possibly new life-saving drugs that are not funded in the public health system.

Most providers also offer policies that provide different levels of reimbursement. For example 50%, 80% or 100% of treatment costs.

Of course, the higher the level of cover offered by a health insurance policy, the greater its cost.


Waiting periods and exclusions: need to know

Most private health policies have a set period of time you must wait after joining before you can claim for certain services. For example, hospital treatment for pre-existing conditions like pregnancy may have a 12-month waiting period, while extras like dental or optical often have shorter ones. Policies may also have exclusions for specific treatments, so read the fine print. 


Does private health cover have drawbacks?

It can also pay to consider some potential downsides of health insurance, such as:

The cost of premiums 

Cost can be a key barrier to taking out private health insurance, especially in these budget-conscious times. That said, if you already have private health insurance and are considering dropping your cover, it could pay to compare and see if you can get what you need for a more competitive price. 

Potential to be hit with extra costs

Even if you have private health insurance, you could be hit with out-of-pocket costs for treatment. For example, your set excess limit or contribution limit.

Limits can leave you out of pocket 

The extras component of insurance has annual limits that apply, meaning you can only claim up to a certain amount for most services. When it comes to some treatments, providers can impose a "lifetime limit", after which you won't be able to claim anymore.   

Limited choice of providers that offer cover

You may find that your health fund has agreements with specific hospitals or medical practitioners and you'll need to see them in order to receive full benefits.

Likewise, when it comes to extras insurance, health funds sometimes have a network of preferred providers whose services are fully covered.


Tips for negotiating a better deal on your health insurance

Here are four quick ways to review and reduce your costs without sacrificing the protection you need.

1. Review your level of coverage

Avoid paying the lazy tax by checking you're not still covered for services you no longer need – for example, are you paying for pregnancy and birth-related care when your kids are grown up and you don't plan on having more?

2. Check your hospital excess

Opting for a higher excess (for example, $750 instead of $250) can lower your premiums, but make sure you could comfortably afford that amount if you ever need to make a claim. 

3. Focus on extras you will use

Extras cover helps pay for services like dental, optical, and physio services. Focus on extras you actually use.

4. Compare your options

Start by calling your current provider to ask about discounts or policy updates that might suit you better. If you're still paying too much, compare your options to see if there's a better deal for you.
