Every question, every answer, every source

In New Zealand, you can challenge a dispute over replacement value or proof of ownership by asking the insurer, claims handler, or other party to explain their decision in writing, providing evidence to support your position, and escalating the complaint if they refuse to reconsider.

The best approach depends on whether the dispute concerns an insurance claim (such as stolen, lost, or damaged belongings), a rejected claim, or disagreement about how much an item is worth.

1. Establish exactly what is being disputed

• Replacement value: The other party may be offering less than it would reasonably cost to replace the item with an equivalent one, or may be using a second-hand value when your policy provides for replacement cover.
• Proof of ownership: They may say you have not shown that you owned the item, even though you no longer have the original receipt or packaging.
• Both: They may accept that you owned the item but dispute its description, condition, age, or value.

Ask them to identify the specific policy clause or rule they are relying on, the evidence they considered, and how they calculated the amount offered.

2. Gather evidence to support your challenge

You do not necessarily need an original receipt to make a case. The strength of your evidence depends on the item and the circumstances.

Dispute	Useful evidence
Ownership	Bank or credit-card statements, order confirmations, emails, warranty registrations, loyalty-account purchase history
Replacement value	Current prices for the same item or a comparable model from multiple New Zealand retailers
Item's specifications	Photos, serial numbers, model numbers, manuals, product listings
Age and condition	Photos, maintenance records, repair invoices, messages mentioning the item
Items without receipts	Gift records, photographs showing you using the item, statements from people who saw or gifted it

These are examples of supporting evidence, not a guarantee that the other party must accept each item. Explain any gaps in your records and provide several independent pieces of evidence where possible.

3. Challenge the replacement amount

Prepare a short comparison showing:

• The exact item you owned, including brand, model, specifications and condition.
• The current cost of replacing it with an equivalent item.
• Why the insurer's proposed replacement or valuation is inadequate.
• Links, screenshots or written quotes supporting your figure.

For example, if your insurer offers $600 for a laptop but equivalent laptops cost $1,000–$1,200, provide comparable specifications and prices. Also check whether your policy provides for replacement cover or indemnity (current value), as these can produce different settlement amounts.

Ask the insurer to explain any deductions, depreciation, excess, policy limits or differences in specifications.

4. Make a formal complaint in New Zealand

If the other party will not reconsider, follow these steps.

1. Complain to the insurer or claims handler in writing.

   State clearly that you are making a formal complaint. Attach your evidence, identify the amount or decision you dispute, and specify the outcome you want.

2. Request an internal review.

   Ask for a review by someone who was not responsible for the original assessment, if possible. Request a written explanation of the final decision.

3. Escalate to the relevant independent dispute resolution scheme.

   Financial service providers must belong to an approved scheme. Your provider can tell you which one covers it. Depending on the provider, this may be the Insurance & Financial Services Ombudsman (IFSO) Scheme or another approved scheme. The service is generally free for eligible consumers.

4. Consider other dispute options if necessary.

   Depending on the type of dispute, amount involved and applicable rules, the Disputes Tribunal or a court may be an option. Get advice before pursuing parallel processes.

Subject
: Formal complaint — disputed replacement value and/or proof of ownership

Dear Claims Team,

I am writing to formally dispute the assessment of my claim, reference [claim number], concerning [item or items].

I disagree with the decision regarding [replacement value / proof of ownership / both] for the following reasons:

1. Ownership: I have provided [list available evidence], which supports my ownership of the item(s). Please explain specifically why this evidence has been considered insufficient and what additional evidence you require.

2. Replacement value: The assessed amount of $[amount] does not adequately reflect the cost of replacing the item with an equivalent product. I have attached comparable pricing and supporting information indicating a reasonable replacement cost of $[amount].

3. Basis of decision: Please identify the relevant policy provisions, valuation methodology, deductions and evidence relied upon in reaching your decision.

I request a formal review of the assessment and a written response addressing each of these points. My preferred resolution is [revised settlement amount / acceptance of the ownership evidence / reassessment of the claim].

Please also advise me of the next steps in your complaints process and the details of your independent dispute resolution scheme if the matter cannot be resolved.

I look forward to your response.

Kind regards,

[Your name]
