What Affects Your Health Insurance Cost?
Understanding the factors that influence your premium helps you make strategic decisions about coverage and identify potential savings opportunities.
1. Age (40-60% of premium calculation)
The single biggest factor affecting health insurance cost. Premiums roughly double every 15 years, with significant jumps at ages 50, 60, and 70.
Impact: Age 30 vs Age 60 = 500-600% increase in premiums
2. Coverage Level (20-30% of premium calculation)
The comprehensiveness of your plan directly impacts cost. Budget plans cover major surgery only, while premium plans include GP visits, prescriptions, dental, and optical.
Impact: Basic vs Premium plan = 80-120% cost difference
3. Excess Amount (10-20% of premium calculation)
Higher excess reduces premiums significantly. Standard excess options range from $0 to $2,500. Doubling your excess from $500 to $1,000 typically reduces premiums by 15-20%.
Impact: $500 excess vs $1,500 excess = 25-35% premium reduction
4. Pre-Existing Conditions (0-50% loading)
Existing health conditions can result in exclusions, premium loadings, or waiting periods. Common loadings: Diabetes (15-30%), cardiovascular conditions (20-40%), mental health history (10-25%).
Impact: Significant pre-existing conditions = 30-50% premium increase or exclusions
5. Smoking Status (10-25% loading)
Smokers pay significantly higher premiums due to increased health risks. Some insurers impose loadings of 20-25%, while others have specific smoker tiers.
Impact: Smoker vs Non-smoker = 15-25% premium increase
6. Occupation (5-15% variation)
High-risk occupations (construction, fishing, forestry) may face premium loadings, while low-risk professional occupations sometimes receive discounts.
Impact: High-risk occupation = 10-15% loading; Professional discounts = 5-10% reduction
7. Payment Frequency (5-10% variation)
Annual payments avoid monthly administration fees and interest charges. Monthly payments typically cost 5-10% more annually.
Impact: Monthly vs Annual payment = 5-10% cost increase
8. Provider & Plan Type (15-25% variation)
Provider choice significantly impacts cost for similar coverage. Southern Cross charges premium prices for market-leading coverage, while nib offers value-focused pricing.
Impact: Southern Cross vs nib for equivalent coverage = 15-20% price difference
Is Health Insurance Worth It in New Zealand?
With New Zealand's public health system providing free hospital care, many Kiwis question whether private health insurance offers value for money. The answer depends on your circumstances, age, and healthcare priorities.
When Health Insurance Makes Sense
- ✓You can't afford extended time off work: Public wait times for elective surgery average 4-6 months. Private insurance enables surgery within weeks.
- ✓You're over 40: Health risks increase, making insurance more valuable. Lock in coverage before pre-existing conditions develop.
- ✓You have family history of health conditions: Insurance provides peace of mind and faster access to specialists and diagnostics.
- ✓You're self-employed or run a business: Can't afford extended recovery time. Insurance ensures quick treatment and return to work.
- ✓You value choice and comfort: Private hospitals offer private rooms, choice of specialist, and convenient appointment times.
When You Might Skip Insurance
- ✗You're young and healthy with no family history: Risk is low, premiums might exceed likely claims. Consider starting coverage by age 30-35.
- ✗You have significant savings (6-12 months expenses): Can self-fund private treatment if needed without financial stress.
- ✗Premiums exceed 5% of household income: Insurance may strain budget. Consider reducing coverage level rather than dropping entirely.
- ✗You're comfortable with public system wait times: If you can wait 4-6 months for elective procedures, public system may suffice.
- ✗Multiple pre-existing conditions mean high loadings/exclusions: Insurance may offer limited value if key conditions are excluded.
Real Cost Comparison Example:
Scenario: 45-year-old needing hip replacement surgery
Public System:
- • Cost: Free
- • Wait time: 6-12 months
- • Time off work: 8-12 weeks
- • Lost income (if no sick leave): $10,000-$15,000
- • Total cost: $10,000-$15,000
Private Insurance:
- • Annual premium: $3,000
- • Excess: $500
- • Wait time: 2-4 weeks
- • Time off work: 6-8 weeks
- • Lost income: $5,000-$8,000
- • Total cost: $8,500-$11,500
8 Ways to Save on Health Insurance Premiums
Increase Your Excess
Moving from a $500 to $1,000 excess typically reduces premiums by 15-20%. From $500 to $1,500 saves 25-30%. Ensure you can afford the higher excess if claiming.
Potential Savings: $300-$800/year
Join Before Age 30
Establishing health insurance before pre-existing conditions develop means no loadings or exclusions. Premiums are lowest in your 20s, and you lock in coverage for life.
Potential Savings: Avoid 30-50% loadings
Compare Annually
Health insurance is not a "set and forget" product. Comparing providers annually can save $400-$1,200 for similar coverage. Providers compete aggressively for new customers.
Potential Savings: $400-$1,200/year
Choose Right Coverage Level
Don't over-insure. If you rarely visit GPs, skip everyday health extras and focus on surgical cover. Mid-tier plans often provide best value.
Potential Savings: $600-$1,500/year
Pay Annually
Monthly payments include administration fees and interest, costing 5-10% more annually. Pay yearly if possible to avoid these charges.
Potential Savings: $150-$400/year
Family Plan vs Individual
Family plans save 15-25% compared to individual policies for each member. Children often covered free or at heavily discounted rates under family plans.
Potential Savings: $800-$2,000/year
Wellness Programs
AIA Vitality rewards healthy behaviors with premium discounts up to 25%. Even small lifestyle improvements (regular exercise, health checks) reduce premiums.
Potential Savings: $250-$900/year
Professional Discounts
Many professional associations, unions, and employers negotiate group discounts with insurers. Check if your employer or professional body offers health insurance benefits.
Potential Savings: $200-$600/year
Frequently Asked Questions
How much does health insurance cost in NZ on average?
Average health insurance costs in New Zealand range from $1,200-$3,500 per year for adults, depending on age and coverage level. A 30-year-old pays approximately $1,490/year for mid-level comprehensive coverage, while a 60-year-old pays around $9,000/year for equivalent cover.
Why does health insurance get more expensive as I age?
Health insurance premiums increase with age because the risk of requiring medical treatment rises significantly as you get older. Statistically, people over 50 make 3-4 times more claims than those under 35. Insurers price policies to reflect this increased risk, with the steepest increases occurring at ages 50, 60, and 70.
Is Southern Cross more expensive than nib and AIA?
Yes, Southern Cross typically costs 15-20% more than nib and 10-15% more than AIA for similar coverage levels. However, Southern Cross offers the largest provider network, highest claim approval rates, and most comprehensive coverage options, which many consider worth the premium pricing.
Do health insurance premiums increase every year?
Yes, health insurance premiums typically increase annually by 3-8%, exceeding general inflation. Increases reflect rising healthcare costs, new medical technologies, and your increasing age. You'll receive notice of premium changes 30-60 days before renewal, giving you time to review options or switch providers.
Are pre-existing conditions covered by health insurance?
Pre-existing conditions are generally excluded from new health insurance policies, or covered with premium loadings of 20-50%. However, once you've held continuous health insurance for 3-5 years (depending on provider), new conditions that develop are covered. This is why joining before health issues arise is so valuable.
Can I claim tax deductions on health insurance?
No, health insurance premiums are generally not tax-deductible in New Zealand for personal policies. However, if you're self-employed and health insurance is a business expense, you may be able to claim it. Consult an accountant for specific advice on your situation.
What's the difference between excess and co-payment?
Excess is a fixed amount you pay per claim (e.g., $500) before insurance covers the rest. Co-payment is a percentage of the total cost you pay (e.g., 20% of specialist fees). Most NZ health insurance policies use excess rather than co-payments. Higher excess means lower premiums.
Will switching providers affect my coverage?
When switching providers, any new conditions that developed while with your old insurer will be treated as pre-existing conditions by the new insurer, potentially leading to exclusions. However, if you've had continuous health insurance, most providers offer limited portability where existing coverage continues. Always check before switching.
