One of the most common misconceptions in New Zealand is that ACC makes income protection insurance unnecessary. It doesn’t. Here’s exactly what ACC covers, where it falls short, and why income protection fills the gap.
What ACC Covers
The Accident Compensation Corporation (ACC) provides New Zealand’s comprehensive accident compensation scheme. It’s funded through levies on wages, businesses, and fuel — and it covers virtually everyone in NZ, regardless of fault.
If you’re injured in an accident, ACC provides:
- Weekly compensation: Up to 80% of your pre-injury earnings (up to an annual earnings cap — approximately $139,000 in 2026) for as long as you’re unable to work due to the injury
- Medical treatment: GP visits, surgery, rehabilitation, physiotherapy, and other treatment costs related to the injury
- Lump sum: For permanent impairment in serious cases
- Home help and childcare: If you can’t perform these due to your injury
- Fatal injury support: For families of those who die in accidents
ACC cover is automatic — you don’t need to apply or have private insurance. It starts from day one of an accident.
What ACC Does NOT Cover
This is the critical gap most New Zealanders don’t fully appreciate.
ACC does not cover:
- Illness of any kind — heart attacks, cancer, diabetes, mental health conditions, back pain caused by a degenerative condition, stroke, chronic fatigue
- Income loss above the cap — earnings above ~$139,000/year (2026) are not fully protected even for accidents
- Self-employed income that’s hard to verify — ACC compensation is calculated from your declared earnings; if your income fluctuates or you’ve recently started a business, the calculation may understate your real income
- The first week of an accident claim (a stand-down period may apply depending on the policy type)
- Redundancy or unemployment — ACC is strictly for accident injury
In practice: The majority of work absence lasting more than a few weeks is due to illness, not accidents. Heart disease, cancer, and mental health conditions collectively account for far more long-term work absence than physical accidents. ACC covers none of this.
What Income Protection Insurance Covers
Income protection insurance pays a regular monthly benefit (typically 75% of your pre-disability income) if you’re unable to work due to illness or injury.
The “or injury” part overlaps with ACC for accidents — but most policies are structured to:
- Pay any ACC-covered amount first
- Top up to the agreed benefit level if ACC pays less than the policy benefit
- Pay the full benefit if ACC doesn’t apply (i.e. the disability is illness-related)
In practice, income protection is most valuable for illness — which ACC doesn’t cover at all.
Example: Why You Need Both
Scenario A — Accident (ACC applies)
James (45, earns $95,000) breaks his back in a cycling accident. He can’t work for 6 months.
- ACC pays 80% of his income = $76,000 annualised = $6,333/month
- His mortgage is $4,500/month, family living costs are $5,000/month
- ACC is sufficient here — he’s reasonably covered
Scenario B — Illness (ACC doesn’t apply)
James is diagnosed with lymphoma. Chemotherapy means he can’t work for 12 months.
- ACC pays nothing — cancer is an illness, not an accident
- His income drops to zero
- His mortgage and family costs continue
- Without income protection, he faces financial crisis
Income protection pays ~$5,937/month (75% of income), covering most of his household costs while he receives treatment.
The ACC Levy — You’re Already Paying for Accident Cover
Every New Zealand employee already pays into ACC via their PAYE — currently around 1.6% of earnings (varies). This is your accident cover, built in.
Because you’re already covered for accidents, income protection insurance can be structured to cover illness only (removing accident cover and reducing the premium). Many NZ income protection policies are structured this way.
Summary: ACC vs Income Protection
| ACC | Income Protection Insurance | |
|---|---|---|
| Covers accidents | Yes | Yes (or tops up ACC) |
| Covers illness | No | Yes |
| Covers mental health conditions | Only if caused by accident | Yes (most policies) |
| Automatic (no application) | Yes | No — must purchase |
| Weekly/monthly benefit | 80% up to cap | 75% typically |
| Funded by | Levies (auto) | Premiums (you pay) |
| Day one cover | Yes | After waiting period |
Who Needs Income Protection Insurance?
- Anyone who would face financial hardship if they couldn’t work for 3–12+ months due to illness
- Self-employed people (no employer sick leave or group cover)
- Employees with a mortgage and dependants
- People with variable income who can’t absorb a gap in earnings
The main exceptions: people with very large liquid savings (6+ months of expenses), or those whose partner’s income alone is sufficient to cover all costs indefinitely.
