NSW Regulator Penalises NRMA Insurance A$479,500 Over Eight CTP Pricing Failures, Led by an Address-Data Error That Overcharged More Than 41,000 Policyholders About A$12.2 Million

The New South Wales State Insurance Regulatory Authority, known as SIRA, has imposed A$479,500 in civil penalties on Insurance Australia Limited, which trades as NRMA Insurance, over eight separate premium pricing failures in its compulsory third party (CTP) insurance book. SIRA issued the penalties on October 22, 2026, and Insurance Business Australia reported the decision on October 28. The details in this article come from that report. The article does not mention a court, and the decision document itself was not reviewed.

How the penalty was set

The total of A$479,500 already includes a 15% discount on the combined figure. SIRA applied the discount because several of the errors shared a root cause in the HUON operating environment and reflected broader control weaknesses. That is, the regulator treated them as related, not as eight unconnected mistakes. The report also gives a history. In December 2024, SIRA imposed a A$10,000 penalty on NRMA Insurance for failures to apply demerit-point loadings correctly, which affected tens of thousands of CTP policies. The report says the later penalty bill is nearly 48 times larger. On March 31, 2026, special licence conditions were placed on NRMA's CTP licence.

NRMA argued that a formal warning would be more appropriate, citing its cooperation, its corrective action and the licence conditions. SIRA gave weight to its remediation but found that penalties were warranted because of the seriousness of the failures, the impact on customers and the CTP scheme, the control breakdowns and the need for deterrence.

The eight matters

1. The HUON address-data error, described as the most serious. An address-data misconfiguration caused the wrong rating districts to be applied. About 41,564 policies were affected, with estimated gross overcharges of about A$12,175,687, or roughly A$12.2 million, across more than 41,000 policyholders. Simple arithmetic on those two figures gives an average of about A$293 per affected policy, a calculation made here and not stated in the report.

2. A missed discount. For 19 months, from April 2024 to November 2025, NRMA did not apply a discount that it had filed with the regulator to eligible new customers. About 16,033 policies were affected, with estimated overcharges of about A$662,000.

3. Vehicle-risk weightings. Incorrect weightings were uploaded to the pricing system, touching about 303,475 policies. Most of the financial gap was undercharging, of about A$1.7 million, which NRMA did not seek to recover from customers.

4. Loyalty-tenure data. From April 2024, inaccurate loyalty-tenure information appeared in CTP renewal documents and was used to calculate renewal discounts. About 727,000 policies need data review and about 611,000 customers need assessment. The report stresses that these are review populations and not confirmed affected populations, and that SIRA said the penalty was not based on any assumed customer loss.

5. Cancellation refunds. Refunds were calculated from the wrong date, short-changing about 15,176 policyholders by an estimated A$118,421.

6. Risk-state mapping. Incorrect mapping affected 2,831 policies.

7. The pricing cap. A wrong input to the malus factor, the element that sets the maximum premium, pushed premiums above the regulatory ceiling for about 24,579 policies over 19 days in early 2026.

8. An outdated premium filing. For 12 days in January 2025, NRMA used an outdated premium filing, which resulted in an under-collection of A$81,568 in statutory levies.

The breadth of the list shows that the problems were not confined to one rating factor. They involved address data, discounts, weightings, refunds, mapping, a cap and a filing. SIRA's decision to treat them together under a discount reflects its finding of a common control weakness.

What happens next

The penalties do not end NRMA's obligations. It must finish outstanding customer remediation, comply with the special licence conditions and meet other regulatory requirements. The decision states that further non-compliance may lead to further regulatory action. The report does not detail the remediation timeline, and it does not give the number of contraventions beyond the eight matters.

What it means for drivers and insurers

For drivers, the practical point is that CTP premiums in New South Wales are calculated from filed rates and regulated rules, and that errors in the inputs can lead to overcharges. The report does not say how customers will be repaid or contacted, so affected drivers should look for direct communication from NRMA. For insurers, the decision shows that data governance in pricing systems is a regulatory issue, not only an operational one, and that regulators may escalate penalties when similar failures recur.

Scale in context

The eight matters touch very different numbers of policies. The largest by reach is the vehicle-risk weighting error, which touched about 303,475 policies, and the loyalty-tenure review populations of about 727,000 policies are larger still. But the money involved is not proportional to the number of policies. The address-data error affected about 41,564 policies and produced overcharges of about A$12.2 million, whereas the vehicle-risk weightings involved a larger number of policies and most of the financial gap ran in customers' favour, as undercharging of about A$1.7 million that NRMA did not seek to recover. The pattern shows why SIRA looked at the seriousness and control breakdowns and not only at the dollar totals, and why it said the penalty for the loyalty-tenure matter was not based on any assumed customer loss.
