Partners Life vs AIA NZ: Head-to-Head Comparison for 2026
Partners Life and AIA New Zealand are both Auckland-headquartered, adviser-only insurers, so neither sells direct to the public in New Zealand. Partners Life, founded here in 2011, is the benchmark for trauma breadth, partial payment tiers and own-occupation TPD. AIA has traded in New Zealand since 1981, is part of the listed pan-Asian AIA Group, and runs the Vitality programme that converts healthy behaviour into premium discounts.
In short
- Partners Life paid 95% of all assessed claims in the year assessed 1 April 2024 to 31 March 2025 (*This is Partners Life 2025* claims brochure, retrieved 18 August 2026).
- AIA accepted 92% of the claims it received in calendar 2024 (Chatswood summary of AIA's Claims Compass, 13 May 2025) and 91% in calendar 2025 (riskinfo NZ, 12 May 2026), both retrieved 18 August 2026.
- The Reserve Bank's register of licensed insurers records a Fitch AA against AIA New Zealand Limited and an A.M. Best A against Partners Life Limited (RBNZ register of licensed insurers, retrieved 18 August 2026).
Partners Life Limited and AIA New Zealand Limited are both Auckland-headquartered, adviser-only insurers writing the full personal risk range, which is why they are so often set against each other when shopping for life insurance. They separate on financial strength: the Reserve Bank's register of licensed insurers records a Fitch AA against AIA New Zealand Limited and an A.M. Best A against Partners Life Limited (retrieved 18 August 2026).
But they are not the same. They differ in pricing philosophy, claims experience, financial backing, and the types of customers they tend to suit best. This guide breaks down every meaningful difference so you can make an informed choice, or at least have a better conversation with your adviser.
At a Glance: Partners Life vs AIA
Partners Life and AIA NZ are both headquartered in Auckland and distribute only through advisers, offering life, trauma, TPD, income protection, health, mortgage protection and funeral cover in New Zealand. Partners Life was founded in 2011 and paid 95% of all assessed claims in the year to 31 March 2025 (*This is Partners Life 2025* claims brochure, retrieved 18 August 2026); AIA has operated locally since 1981, carries a Fitch AA rating on the Reserve Bank's register of licensed insurers (retrieved 18 August 2026) and runs the Vitality programme.

Company Backgrounds
Partners Life was founded in New Zealand in 2011 by Naomi Ballantyne, is privately held, and was built from the ground up as an adviser-only insurer known for product innovation. AIA has operated in New Zealand since the early 1980s as part of AIA Group, one of the largest listed pan-Asian life insurance groups.
Partners Life
Partners Life was founded in 2011 by Naomi Ballantyne, one of New Zealand's most recognised figures in the insurance industry. Despite being a relatively young insurer, Partners Life has grown rapidly to become one of the largest life insurers in the country by new business volume.
The company was built from the ground up as an adviser-only insurer, meaning you cannot buy directly from Partners Life. This model means every policy is placed through a licensed financial adviser, which tends to result in better-matched cover for the customer.
Partners Life is privately held and New Zealand-founded, which appeals to Kiwis who prefer supporting local businesses. The company has earned a reputation for product innovation, regularly updating its policy wordings to stay competitive.
AIA NZ
AIA has been operating in New Zealand since the early 1980s and is part of the AIA Group, one of the largest independent publicly listed pan-Asian life insurance groups in the world.
Like Partners Life, AIA NZ distributes through financial advisers rather than selling direct to the public. The company is well known for its AIA Vitality programme, a wellness and rewards platform that incentivises healthy behaviour and can reduce premiums over time.
AIA's global backing gives it a level of financial strength that is hard to match among local competitors, and the Fitch AA recorded against AIA New Zealand Limited on the Reserve Bank's register of licensed insurers (retrieved 18 August 2026) reflects that.
Product Range Comparison
Partners Life and AIA both offer a full suite of personal risk products in New Zealand, and they compare closely across the main cover types, with Partners Life the benchmark for trauma breadth, partial payment tiers and own-occupation TPD, and AIA holding the more established health insurance range and stronger claims infrastructure.
Life Cover
Both insurers offer standard life cover with similar core benefits. Partners Life tends to offer more built-in benefits and options within its life cover, including a wider range of special events increases and conversion options. AIA's life cover is solid and well-regarded but typically has fewer customisation options baked into the base policy.
Trauma (Critical Illness) Cover
This is where meaningful differences appear. Partners Life offers one of the most comprehensive trauma definitions in the New Zealand market, with a broad list of covered conditions and partial payment options across multiple severity levels. AIA also provides strong trauma cover, but historically Partners Life has been the benchmark for trauma product breadth.
Income Protection
Both insurers offer income protection with agreed value and indemnity options, various benefit periods, and waiting period choices. Partners Life is known for offering more flexibility around benefit structures, including options for specific occupation cover at competitive rates. AIA's income protection is competitive and benefits from the insurer's strong claims infrastructure.
If you are weighing up income protection options more broadly, the differences between these two often come down to the fine print and your specific occupation.
Total Permanent Disablement (TPD)
Both offer standalone and accelerated TPD cover. The definitions are broadly similar, though Partners Life's own-occupation TPD definition is considered among the strongest in the market. For a deeper look at TPD, see our guide on TPD insurance in New Zealand.
Health Insurance
AIA offers a full suite of health insurance products, including everyday cover, surgical cover, and comprehensive plans. Partners Life also offers health cover, though AIA is generally considered to have a more established health insurance proposition with a wider range of plan options.
Claims Data Comparison
Partners Life paid 95% of all assessed claims in the year assessed 1 April 2024 to 31 March 2025 (*This is Partners Life 2025* claims brochure, retrieved 18 August 2026), and AIA accepted 92% of all claims received in calendar 2024 (Chatswood summary of AIA's Claims Compass, 13 May 2025, retrieved 18 August 2026) and 91% in calendar 2025 (riskinfo NZ, 12 May 2026, retrieved 18 August 2026). Both are strong for the New Zealand market, though the periods and denominators differ, and decline rates can be influenced by product mix, advice quality at the point of sale and how strictly non-disclosure is enforced.
| Claims Metric | Partners Life | AIA NZ |
|---|---|---|
| Overall Claims Acceptance Rate | 95% of assessed claims, Apr 2024 – Mar 2025 | 92% of claims received in 2024; 91% in 2025 |
| Claims Reputation | Strong, adviser feedback consistently positive | Good, though slightly lower acceptance rate |
| Claims Process | Streamlined, adviser-supported | Structured, thorough assessment process |
Partners Life's 95% of assessed claims is among the highest figures published in the New Zealand market (*This is Partners Life 2025* claims brochure, claims assessed 1 April 2024 – 31 March 2025, retrieved 18 August 2026). AIA's 92% of claims received in 2024, easing to 91% in 2025, is still strong (riskinfo NZ, 12 May 2026, retrieved 18 August 2026), but the gap is notable. Note that Partners Life measures assessed claims and AIA measures claims received, so the two are not strictly like-for-like.
It is worth understanding that claims decline rates can be influenced by many factors, including the types of products sold, the quality of advice at the point of sale, and how strictly non-disclosure is enforced. A higher acceptance rate does not automatically mean one insurer is "better" than another, but it is a meaningful data point.
Both insurers publish their claims data annually, and both have dedicated claims teams that work with advisers to support customers through the process.
Financial Strength Ratings
The Reserve Bank's register of licensed insurers records a Fitch AA against AIA New Zealand Limited and an A.M. Best A against Partners Life Limited (retrieved 18 August 2026), so AIA has the clear edge on financial strength between the two in New Zealand. Both ratings sit well above the minimum required to operate, indicating a high degree of safety for policyholders.
| Rating | Partners Life | AIA NZ |
|---|---|---|
| Rating | A | AA |
| Rating Agency | A.M. Best | Fitch |
| What It Means | Strong ability to meet ongoing obligations | Very strong ability to meet ongoing obligations |
AIA has the edge here, and it is not close. AA is the highest grade recorded against any major New Zealand life insurer on the Reserve Bank's register (retrieved 18 August 2026). This is largely due to the backing of the AIA Group, which has vast reserves and global diversification.
Partners Life's A rating from A.M. Best, also recorded on the Reserve Bank's register, is still strong and well above the minimum required to operate in New Zealand. For most consumers, both ratings indicate a high degree of safety. However, if financial strength is your primary concern, AIA has a clear advantage.
For context, you can compare these ratings with other insurers in our best life insurance companies in NZ guide.
Pricing Comparison
Neither Partners Life nor AIA publishes standard rate cards in New Zealand, and premiums vary by age, health, occupation, smoking status and the cover selected. Partners Life is generally competitively priced, particularly on trauma and income protection, while AIA sits mid-range unless Vitality members earn premium discounts through active engagement.
Partners Life tends to be competitively priced across most product lines, particularly for trauma and income protection cover. The insurer is known for aggressive pricing on new business, and advisers frequently note that Partners Life comes in at or near the lowest premium for comparable cover.
AIA premiums tend to sit in the mid-range of the market. However, AIA Vitality members who actively engage with the programme can earn premium discounts, which can make AIA more competitive over time for health-conscious customers. The discount is earned rather than given, and the current rules are worth confirming with AIA or your adviser.
The best way to compare pricing for your specific situation is to get quotes through an adviser who can run illustrations across multiple insurers side by side.
Unique Features
AIA's unique feature in New Zealand is the Vitality programme, which tracks exercise, preventive health checks and nutrition and converts points into premium discounts and partner rewards. Partners Life's differentiator is flexibility, through customisable policy structures, broader trauma definitions with more partial payment tiers and strong conversion privileges.
AIA Vitality
AIA's standout differentiator is the Vitality programme. This is a wellness and rewards platform that tracks healthy behaviours such as exercise, preventive health checks, and nutrition. Members earn points that translate into:
- Premium discounts that rise and fall with your engagement
- Partner rewards (retail discounts, entertainment offers)
- Health and fitness incentives
AIA Vitality is a genuine value-add for customers who are already health-conscious or want extra motivation to improve their wellbeing. It is less valuable for customers who are unlikely to engage with the programme regularly.
Partners Life Flexibility
Partners Life's key differentiator is the flexibility built into its product suite. The insurer offers:
- More customisable policy structures
- Broader trauma definitions with more partial payment tiers
- A wider range of special events increase options
- Strong conversion privileges across products
- Regular product updates that respond to adviser and consumer feedback
Partners Life's adviser-centric model means the company is highly responsive to feedback from the adviser community, and this often translates into product features that are genuinely useful rather than just marketing points.
Pros and Cons
Partners Life's advantages over AIA in New Zealand are its published payout record (95% of assessed claims, April 2024 to March 2025), broader trauma definitions, competitive pricing and NZ-founded management, against a lower A rating and a shorter track record since 2011. AIA's advantages are the AA rating, the Vitality programme and established health insurance, against 92% of claims received accepted in 2024 and 91% in 2025.
Partners Life
Pros:
- Among the highest published payout rates in the market (95% of assessed claims, April 2024 to March 2025)
- Comprehensive trauma cover with broad definitions
- Competitive pricing across most product lines
- Strong adviser relationships and responsive product team
- New Zealand-founded and locally managed
Cons:
- Lower financial strength rating than AIA (A vs AA)

AIA
Pros:
- Very strong financial strength rating (AA)
- AIA Vitality wellness programme with tangible rewards
- Established health insurance product range
- Backed by one of the world's largest insurance groups
- Long operating history in New Zealand
Cons:

- Mid-range pricing without Vitality engagement
- Less product customisation compared to Partners Life
- Trauma definitions not as broad as Partners Life
Verdict: Who Suits Each Insurer Best
Partners Life suits New Zealanders who want the broadest trauma cover, prioritise its published payout record (95% of assessed claims, April 2024 to March 2025, retrieved 18 August 2026), value product flexibility or prefer an NZ-founded insurer. AIA suits those who rank financial strength and global backing first, will actively use Vitality for premium discounts, or want established health insurance alongside life cover.
Choose Partners Life if:
- You want the broadest possible trauma cover
- Claims acceptance rates are a top priority for you
- You value product flexibility and customisation
- You prefer supporting a New Zealand-founded insurer
- You want competitive premiums without needing to engage with a wellness programme
Choose AIA if:
- Financial strength and global backing matter most to you
- You are health-conscious and will actively use AIA Vitality
- You want a comprehensive health insurance option alongside your life cover
- You prefer the reassurance of a long-established global brand
- You are motivated by wellness rewards and premium discounts
Consider Fidelity Life if:
- You are budget-conscious and looking for solid cover at a lower price point. Fidelity Life is a strong New Zealand-based alternative that often comes in at a lower premium than both Partners Life and AIA, while still offering a respectable product range.
Ultimately, the best approach is to have a licensed financial adviser compare both insurers side by side for your specific situation. Policy wordings, exclusions, and pricing all vary based on individual circumstances, and what works for one person may not be the best fit for another.

Frequently Asked Questions
Is Partners Life or AIA better for life insurance in NZ?
Neither is universally better. Partners Life tends to offer more comprehensive policy wordings and higher claims acceptance rates, while AIA offers stronger financial backing and the Vitality wellness programme. The best choice depends on your individual priorities and circumstances.
Which insurer has better claims rates, Partners Life or AIA?
Partners Life paid 95% of all assessed claims in the year to 31 March 2025 (*This is Partners Life 2025* claims brochure), against AIA's 92% of claims received in 2024 and 91% in 2025 (riskinfo NZ, 12 May 2026); both retrieved 18 August 2026. Both are strong by industry standards, but Partners Life has a slight edge on this measure, bearing in mind the two insurers measure over different periods and denominators.
Is AIA Vitality worth it?
AIA Vitality can be genuinely valuable if you actively engage with the programme. Members who consistently meet activity targets can earn premium discounts that grow over time, and access a range of partner rewards. If you are unlikely to use the programme regularly, the benefit diminishes.
Can I switch from AIA to Partners Life (or vice versa)?
Yes, you can switch insurers, but it is important to do so carefully. Switching means underwriting starts fresh, which could result in new exclusions or loadings based on your current health. Never cancel an existing policy before your new policy is fully in force. A licensed financial adviser can manage this process for you.
Are Partners Life and AIA the only options in NZ?
No. New Zealand has several quality life insurers, including Fidelity Life, Asteron Life, nib, and Chubb. Each has different strengths. For a broader view, see our guide on the top life insurance companies in New Zealand.
Do I need an adviser to get Partners Life or AIA cover?
Yes. Both Partners Life and AIA are adviser-only insurers, meaning you cannot purchase policies directly. You will need to work with a licensed financial adviser. QuoteHub connects you with advisers who can compare both insurers for your situation.
