Most Satisfied Customers Award | AA Health Insurance

AA Health Insurance rated No.1 by Kiwi health insurance consumers for delivering total customer satisfaction.

How we rate health insurance providers

Our review compares health insurance providers on customer satisfaction, so you can discover what other Kiwis think about our compared health insurance providers before you sign up for a policy. Think of it like asking hundreds of your closest friends and family members which health insurance providers they think deliver the best heath cover and value for money.

Canstar surveyed 1288 Kiwis who currently pay for health insurance cover and asked them for their feedback on their choice of health insurance provider.

  • The outcomes reported in these ratings are measured via accredited research panels managed by Qualtrics.

Respondents rate their satisfaction with their health insurance providers from zero to ten, where zero is extremely dissatisfied and ten is extremely satisfied. Brand satisfaction was rated by respondents on the following criteria:

  • Overall Satisfaction: measures consumer satisfaction with a health insurance provider as an individual score NOT a combined total of all criteria.
  • Communication: the insurer is proactive in keeping policy holders up-to-date and informed about their cover levels, and throughout any insurance claim.
  • Comprehensiveness of Cover: each policy offers a wide range of cover benefits that are in keeping with its cost.
  • Cost: policy costs compare favourably with those of other health insurance providers.
  • Customer Service: the insurer delivers high levels of customer service throughout the health insurance purchase journey, from onboarding and claims, through to cancellation or change of policy.
  • Value for Money: the health insurer’s policies offer good value for money when comparing costs with levels of cover.

The winning health insurance provider is the one that receives the highest Overall Satisfaction rating once all the scores from the Overall Satisfaction criteria are combined and averaged.

  • Overall Satisfaction is asked as a specific question and represents an individual measure, not a combined total of all criteria.
  • When we cannot determine a clear winner from the criteria for the Overall Satisfaction rating, we will then look at the other criteria measured in the rating.
    • The provider with the highest number of five-star ratings within the supporting criteria will become the five-star recipient in overall satisfaction, and thus win the award. If a clear leader still cannot be determined from the supporting criteria, joint winners will be declared.

Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.

Choosing the Right Health Insurance Provider for You

Each year, when Canstar undertakes its health insurance consumer research, we hear the same concerns about the price of health insurance, and this year was no different, with almost half (48%) of respondents concerned about the cost of private health insurance.

Therefore, it’s surprising that just 18% of respondents to our survey cite health insurance costs as the biggest driver of their satisfaction with their provider. And, once again, Value for Money rates more highly: this year the main concern of nearly a quarter (23%) of our health insurance consumers.

However, by far the biggest driver of satisfaction is Customer Service. This is understandable. When you’re going through the stress of a period of ill health, the last thing you need to worry about it added concerns about claiming on your policy.

It’s a consistent theme that runs through all our awards research: Kiwi consumers are less concerned about the price of the products and services they buy, if they perceive them to deliver true value for money and great customer service.

Here’s the full rundown of what those in our survey say are the main things they consider when rating their choice of health insurance provider:

  • Customer Service: 28%
  • Value for Money: 23%
  • Comprehensiveness of Cover: 20%
  • Cost: 18%
  • Communication: 11%

About Private Health Insurance

What is Private Health Insurance?

New Zealand’s health and disability system is mainly funded from general taxation. The Ministry of Health allocates more than three quarters of the public funds it manages via Vote Health to District Health Boards (DHBs), who then use this to purchase and provide public health services.

However, the government is currently in the process of making substantial changes to the way the health system is structured, and how it operates. This includes the disestablishment of the DHBs, and the creation of Health NZ and a Māori Health Authority, by July 2022.

Other funding sources include the Accident Compensation Corporation (ACC) and other government agencies. But the public health system does not cover all healthcare and private health insurance covers a wider variety of healthcare options.

More than 1.4 million New Zealanders have private health insurance, according to the Health Funds Association of New Zealand. Having private health insurance means New Zealanders can access treatment without the often-lengthy wait of the public health system. It also gives the policy holder some more control over their healthcare, such as the option of getting cover for extra treatments, such as dental, optical, chiropractic or physiotherapy.

These are a general explanation of the meaning of terms used in relation to health insurance.

Policy wording may use different terms and you should read the terms and conditions of the relevant policy to understand the inclusions and exclusions of that policy.

Annual limit: The maximum benefit payable for a particular service within a 12-month period.

Benefit: The dollar amount paid to you by your health fund when you make a claim with your hospital cover or extras cover.

Benefit limitation period: Benefit limitation periods are a period of time after taking out your health insurance policy where you will only be able to claim a restricted amount of benefit for nominated conditions. This time period usually commences after standard waiting periods have been served.

Claim: When you request that your health funds contributes to the cost of health services provided by a hospital, doctor, or other healthcare provider. If you have already paid the invoice in full, you can make a claim with your health fund afterwards and they will reimburse you with some or all of the cost via a direct payment, such as electronic funds transfer. If the invoice has not yet been paid, the health fund will pay this invoice in full, and then request that you pay them the balance owing (the difference between the actual bill and the amount the health fund will cover).

Compensation or Damages: Fund benefits are not payable when compensation and/or damages may be claimed from another source, such as ACC.

Default Benefits: The minimum level of benefits private health insurers must pay, as set down by the government. These cover claims for treatment provided in public hospitals, non-contracted private hospitals and day surgeries.

Elective surgery: Surgical treatment of a condition that, according to your doctor, does not require immediate attention. Elective surgery waiting lists are one reason why it’s great having health insurance.

Excess: Much like with a car insurance policy, your health insurance policy charges an excess when you make a claim. It is an amount of money you agree to pay for hospital admission or medical services before you can claim anything back from your health fund. An excess does not apply to extras cover.

Exclusions: Any medical procedure, treatment, or health service that is not covered by your policy. You cannot make a claim for these items with your health insurance.

Pre-existing condition: An ailment, illness, or health condition is considered to be pre-existing if, in the opinion of a doctor appointed by the health fund, it existed at any time during the six months prior to the member joining a hospital cover or upgrading to a higher level of cover. Health funds can impose a maximum 12-month waiting period for hospital treatment for ailments, illnesses, or conditions that are considered to be pre-existing.

Premium: The annual payment or monthly payment (or other regular periodic payment) that a policyholder makes to a health insurance company to pay for having health cover.

Restriction: Some hospital cover policies have procedures that are restricted, meaning they will only pay the Public Hospital Benefit for that procedure. Policyholders would pay a considerable gap fee if they chose to be treated for a restricted procedure.

Waiting periods: The time you need to wait after buying health insurance, before you can start claiming benefits on the policy.

Canstar surveyed 5048 New Zealand consumers across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from respondents who have health insurance. In this case, 1288 New Zealanders. Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criterion.

The past winners from Canstar’s Health Insurance ratings:

  • 2022: AA Health Insurance
  • 2021: AA Health Insurance
