There is no statutory time limit for a CTP insurer to change an assessor in NSW. However, delays may affect claim progress and may be challenged if the insurer’s conduct is unreasonable. Document all communications and consider seeking advice if delays impact benefits.

Understanding CTP insurer assessor changes in NSW

A change of assessor by a Compulsory Third Party (CTP) insurer in New South Wales does not trigger a formal time limit under the Motor Accident Injuries Act 2017. There is no provision in NSW law that sets a deadline for an insurer to appoint or replace an assessor. The decision to change an assessor rests with the insurer and is not subject to a fixed statutory timeframe.

However, the timing of an assessor change may affect a claimant’s ability to progress their claim. Delays in assigning or replacing an assessor can impact the processing of treatment and care benefits, weekly income payments, and the assessment of injury impairment. These delays may be relevant if a claimant seeks to challenge the insurer’s conduct or raise concerns about the handling of their claim.

Legal framework for CTP claim management

The Motor Accident Injuries Act 2017 (MAIA) governs CTP claims in NSW. Under this legislation, insurers are required to manage claims in a timely and fair manner. The Act does not prescribe a specific timeframe for changing assessors, but it does require insurers to act reasonably and in good faith.

Assessors are appointed to manage a claim and assess entitlements to benefits such as treatment and care, weekly income payments, and damages. The role of an assessor includes reviewing medical evidence, coordinating treatment, and evaluating the impact of injuries on a claimant’s capacity to work and perform daily activities.

Practical implications for claimants in Greater Sydney

In Greater Sydney, claimants may experience delays in receiving a new assessor if the insurer does not act promptly after a change. While there is no legal deadline, prolonged delays may give rise to concerns about the insurer’s compliance with their obligations under MAIA.

Claimants who believe a change of assessor has caused undue delay in receiving benefits should document all communications with the insurer. This includes correspondence, call logs, and records of any missed appointments or delayed responses. These records may support a complaint to the insurer or a request for review under the Motor Accident Injuries Regulation 2017.

Evidence and documentation that may matter

When a claimant seeks to challenge a delay in assessor change or the handling of their claim, the following evidence may be relevant:

  • Copies of correspondence with the insurer, including emails and letters
  • Records of calls made to the insurer, including dates, times, and names of representatives spoken to
  • Medical reports and treatment plans that were delayed due to the absence of an assigned assessor
  • Evidence of any impact on income, rehabilitation, or daily functioning

These records help establish whether the insurer’s actions were reasonable and whether delays were caused by the insurer’s internal processes.

Dispute resolution and when to seek advice

There is no formal appeal process for a change of assessor in NSW. However, if a claimant believes the insurer has failed to act reasonably in changing or assigning an assessor, they may raise a formal complaint with the insurer. If the complaint is not resolved, the claimant may seek assistance from the State Insurance Regulatory Authority (SIRA).

SIRA provides guidance on how insurers must manage claims, including the need to act in good faith and ensure timely processing. While SIRA does not have the power to order a change of assessor, it can investigate whether an insurer has breached its obligations under MAIA.

A claimant who experiences repeated delays, inconsistent communication, or a lack of transparency from the insurer should consider seeking independent advice. Legal advice may be necessary if the claimant wishes to explore whether the insurer’s conduct constitutes a breach of statutory duty.

Hypothetical example

A pedestrian in Sydney’s Inner West was injured in a motor vehicle accident in July 2024. The CTP insurer initially assigned an assessor, but after three months, the claimant received a letter stating the assessor had been replaced. No explanation was provided, and the new assessor did not contact the claimant for another six weeks. During this time, the claimant was unable to access treatment benefits because the new assessor had not reviewed medical records. The claimant documented all communications and submitted a formal complaint to the insurer. The insurer responded by confirming the change was internal and not subject to a time limit, but agreed to expedite the review.

Next steps and advice

There is no fixed time limit under NSW law for a CTP insurer to change an assessor. The decision is within the insurer’s discretion, but they must act reasonably and in good faith. Delays may affect a claimant’s access to benefits and may give rise to a complaint or review.
