What ACC Doesn't Cover — and How Loan Insurance Fills the Gaps
By Aroha Ngata, Consumer Finance Specialist · May 2026
New Zealand's Accident Compensation Corporation (ACC) is a world-leading no-fault accident compensation scheme. It provides weekly earnings compensation, treatment costs, and rehabilitation support when you're injured. Many New Zealanders believe — incorrectly — that ACC makes income protection and loan insurance redundant. Understanding exactly what ACC does and doesn't cover is essential for any borrower assessing their financial protection needs.
Key Takeaways
- ACC covers accidents only — illness, redundancy, and most mental health conditions are excluded
- Illness is the leading cause of long-term work absence — ACC provides nothing for this
- Cancer, cardiac events, and mental health are the biggest ACC gaps for borrowers
- Income protection and loan insurance fill the illness gap that ACC leaves open
- When both ACC and insurance apply (injury), offset clauses prevent double-dipping
- Mental health cover varies significantly between insurance providers — compare carefully
What ACC Actually Covers
ACC covers personal injury caused by an accident. In practical terms, this means:
Sports injuries
Motor vehicle accidents (even if you're at fault)
Workplace accidents
Falls, fractures, and other physical trauma
Gradual process injuries (like repetitive strain) caused by your work
Some mental injury directly caused by a physical injury
When you make an ACC claim for a covered injury that prevents you from working, ACC pays weekly compensation of up to 80% of your pre-injury earnings (subject to a maximum cap, which is adjusted annually). This can overlap with and supplement loan insurance for injury-related claims.
What ACC Explicitly Does NOT Cover
The gaps in ACC coverage are substantial and directly relevant to loan holders:
Illness: Cancer, heart disease, diabetes, depression, anxiety, autoimmune conditions, neurological disorders — none of these are covered by ACC unless they result from an accident or work-related exposure. Illness is the leading cause of long-term work absence in New Zealand, and ACC provides nothing.
Redundancy and job loss: ACC has no employment protection function. If you lose your job, ACC is irrelevant.
Mental health conditions not linked to injury: The mental health epidemic — depression, anxiety, burnout — is one of the most common causes of inability to work. ACC covers psychological injury directly caused by a physical accident, but standalone mental health conditions are excluded.
Elective surgery complications: If you're unable to work following complications from elective surgery, ACC coverage depends on whether the complication qualifies as a "medical mishap" under specific criteria.
Illness-related death: Life insurance, not ACC, addresses this.
The Illness Gap: Your Biggest Uninsured Risk
Statistics consistently show that illness — not injury — is the primary cause of long-term work absence in New Zealand. Cancer diagnoses, cardiac events, mental health conditions, and autoimmune diseases collectively account for a greater proportion of extended sick leave and disability than accidents.
Yet ACC, our national safety net, covers none of these. A 45-year-old homeowner diagnosed with cancer who cannot work for 18 months receives nothing from ACC. Their mortgage repayments, however, continue unchanged.
This is the single most important gap that loan insurance and income protection fill. For borrowers who believe ACC protects them, understanding that illness is explicitly excluded from the scheme changes the calculus of insurance entirely.
When ACC and Loan Insurance Work Together
For covered injuries, ACC and loan insurance can operate simultaneously, though offset clauses may apply. ACC pays up to 80% of pre-injury earnings; income protection or loan insurance adds additional cover up to the policy's benefit limit.
Many income protection policies have an "ACC offset" clause that reduces the insurance benefit by what ACC pays — ensuring total payments don't exceed your income threshold but also meaning you don't receive a windfall. The insurance's primary value in this scenario is:
Covering the gap between ACC's 80% and your actual income needs
Activating immediately while ACC processes your claim
Providing continuing benefit once ACC's early-stage rehabilitation support transitions to longer-term support
Covering the periods ACC doesn't cover (beyond maximum benefit caps)
Mental Health and Loan Insurance
Mental health conditions — including depression, anxiety, and burnout — are increasingly common causes of work absence. ACC covers psychological conditions only in specific, narrow circumstances (e.g., post-traumatic stress from a covered accident). It does not cover depression arising from workplace stress, relationship breakdown, financial pressure, or other life events.
Income protection policies vary significantly in their mental health coverage. Some include mental health conditions on the same basis as physical illness; others apply stricter definitions, shorter benefit periods, or specific exclusions for pre-existing mental health history. This is an area where reading policy wording carefully — and disclosing any history fully and accurately — is critical.
For borrowers who have previously experienced mental health challenges, specialist advice is especially important to find providers with the most inclusive terms for their specific situation.
Frequently Asked Questions
If ACC pays 80% of my income after an injury, do I still need loan insurance?
ACC's 80% covers you for accidents — but 20% of income is still a shortfall on top-of-mortgage repayments. More importantly, ACC doesn't cover illness. Most loan insurance and income protection products activate for both injury AND illness, providing broader coverage than ACC alone. For accident injuries, the insurance supplements ACC and covers situations ACC doesn't.
Does ACC cover me if I can't work due to stress or burnout?
Generally no. Burnout and work-related stress are not ACC-covered events unless they result from a specific workplace accident (such as witnessing a traumatic event). If stress or mental health prevents you from working, income protection insurance with mental health coverage is the relevant product.
What is the ACC annual earnings cap?
ACC sets a maximum annual earnings cap for weekly compensation purposes, adjusted each year. As of 2026, this cap limits the earnings base for ACC weekly compensation for high earners. If your income exceeds this cap, the portion above it is not covered by ACC weekly compensation — making income protection insurance particularly important for higher earners.
