ACC vs Income Protection: What Sole Traders in NZ Need to Know

New Zealand's ACC scheme is one of the world's most comprehensive no-fault accident compensation systems. For most Kiwis, it's a source of significant reassurance: if you're injured in an accident, you'll get medical treatment and some income support without needing to prove fault or sue anyone.

But for sole traders, ACC has a critical limitation that many don't discover until they're already in trouble.

What ACC Covers for Sole Traders

ACC covers personal injury from accidents. For a self-employed person, this means:

Medical treatment: GP visits, specialist consultations, surgery, rehabilitation — all covered for accident injuries.

Weekly compensation: ACC pays around 80% of your pre-injury earnings (up to an annual cap) if an accident leaves you unable to work. This applies whether you're a wage earner or self-employed.

Lump sum payments: For serious injuries causing significant permanent impairment.

Vocational rehabilitation: If you can't return to your previous work due to an accident injury, ACC may fund retraining.

For sole traders, the weekly compensation calculation is based on your previous year's taxable income. If your income fluctuates or if you've had a low-income year, this can significantly understate what you actually earn.

What ACC Does NOT Cover

Here's the critical gap: ACC only covers personal injury caused by accidents. The full list of what ACC cannot cover includes:

- Illness: Cancer, heart disease, stroke, diabetes, kidney failure, liver disease, and any other non-accident illness - Mental health conditions: Anxiety, depression, burnout — unless directly caused by a work accident (rare in practice) - Gradual process conditions: Back pain, hearing loss, repetitive strain injuries that develop over time rather than from a single accident (some exceptions apply) - Surgery complications: If surgery goes wrong, ACC may cover the complication but only if it meets specific criteria - Overseas accidents: ACC doesn't apply if you're injured abroad (travel insurance required)

The illness exclusion is by far the most significant for sole traders. According to life insurance industry data, illness causes more than 65% of extended disability claims — meaning for most people who end up unable to work for months, the cause is illness, not an accident.

The Income Reality for Ill Sole Traders

Let's be concrete about what happens when a sole trader gets seriously ill:

Day 1: You can't work. Your income stops.

No sick leave: There's no employer to keep paying you.

Business overhead continues: Your ute lease, your insurance premiums, your tools storage — costs keep coming.

ACC says no: Your cancer diagnosis, heart condition, or disc disease isn't an accident. No weekly compensation.

Savings deplete: If you have savings, they start going. If you don't, financial problems begin immediately.

Mortgage stress: If you have a mortgage and household expenses that relied on your sole trader income, the situation can deteriorate rapidly.

This is the scenario that income protection insurance is specifically designed to prevent.

How Income Protection Insurance Works

Income protection (IP) pays a monthly benefit — typically 75% of your pre-disability income — if illness or a qualifying injury prevents you from working. Key features:

Own occupation definition: The best policies pay if you can't do your specific occupation. If you're a plumber and a back condition means you can't plumb, you're eligible — even if you could theoretically do some other kind of work.

Wait period: The time between you stopping work and your first benefit payment. Common periods: 2 weeks, 4 weeks, 8 weeks, 13 weeks, 26 weeks. Longer wait periods mean lower premiums.

Benefit period: How long the benefit pays. Two-year periods are common and affordable. Some policies pay to age 65.

Escalation: Good policies include CPI escalation to keep your benefit in line with inflation.

Real-World Example: The Electrician

Consider a 38-year-old self-employed electrician earning $110,000 per year. He has a mortgage of $480,000 and two kids.

At 38, he's diagnosed with bowel cancer. Surgery and chemotherapy mean he cannot work for 11 months.

Without income protection: - ACC: Zero. Cancer is not an accident. - Income during 11 months: Savings, then nothing - Mortgage: Risk of default after 3-4 months - Business: Cannot sustain without income

With income protection (4-week wait period, to-age-65 benefit): - After 4 weeks: Monthly benefit of ~$6,875 (75% of $110k) - 10 months of benefits: Approximately $68,750 paid out - Mortgage maintained, family financial stability preserved - Premium cost: ~$280/month (approximately $3,360/year)

The cost of 10 months of income protection benefits versus the annual premium: the policy pays for itself many times over in a single claim.

ACC and Income Protection Together

If you have an accident that both ACC covers AND you hold income protection:

Most IP policies include an ACC offset clause. This means your IP policy pays the difference between your ACC weekly compensation and your policy benefit, rather than the full benefit. So you won't be paid double — the policies work together to bring you up to your insured benefit level.

This is actually efficient: your IP premium is partly reduced because the insurer knows ACC will bear some of the cost for accident claims.

Choosing Your Income Protection Policy

Key decisions for sole traders:

Wait period: If you have 3 months of living expenses in savings, a 4-8 week wait period is typically appropriate. If you have minimal savings, consider a 2-week wait period (higher premium but faster income support).

Benefit period: Two years covers most recoveries. To-age-65 protection provides more comprehensive protection for long-term or permanent disability. The premium difference is significant but so is the protection.

Own vs any occupation: Always choose own occupation if available. Any occupation cover only pays if you're completely unable to work in any capacity — a much higher bar.

Medical history: IP underwriting is health-specific. Pre-existing conditions are typically excluded. Apply while you're young and healthy if you can — premiums are lower and you're more likely to get full cover.

Talk to an adviser who can compare terms from NZ's main IP providers — AIA, Asteron Life, Partners Life, Fidelity Life, and Chubb Life — and find the best combination of coverage and premium for your situation.
