10 Ways to Reduce Your Home Insurance Premium in NZ

If you have opened your home insurance renewal notice recently and felt your stomach drop, you are not alone. Premiums across New Zealand have increased substantially over the past few years, driven by rising construction costs, increased natural disaster claims, and reinsurance market pressures. The change for an individual household depends on its property, risk information, sum insured, claims history, insurer and policy terms.

The good news is that you are not entirely powerless. Some quoted inputs can be reviewed, but each change can affect cover or the amount payable at claim time. Here are ten checks to discuss with insurers or a broker.

1. Increase Your Excess Strategically

Your excess is the amount you pay out of pocket before insurance kicks in. Excess amounts and options vary by insurer, policy section and type of claim. Ask for quotes at available excess levels and check whether more than one excess can apply.

This approach only makes sense if you have sufficient savings to cover the higher excess should you need to claim. A higher excess may reduce the quoted premium, but the saving is not fixed and must be weighed against the amount payable if a covered event occurs.

2. Bundle Your Policies

Some providers offer multi-policy pricing. Compare the combined total with separate policies and keep the sums insured, excesses, limits, exclusions and optional benefits aligned.

• A multi-policy quote may or may not reduce the combined cost
• Renewal and payment dates depend on the provider and policies
• Claims handling arrangements depend on the provider and event
• Check whether any discount is conditional and how it changes at renewal

That said, bundling is not always the cheapest option. Run the numbers both ways before committing, as sometimes separate specialist providers offer better value for individual products.

3. Install Security Upgrades

Insurers may ask about security features, but recognised devices, installation standards and any price effect vary. Obtain the insurer’s written requirements and revised quote before buying an upgrade for insurance reasons.

Before investing in security upgrades specifically for insurance savings, check with your insurer about which measures they recognise and the discount you would receive. Some insurers are quite specific about requirements.

4. Review Your Sum Insured Regularly

Your sum insured should reflect the actual cost to rebuild your home, not its market value or rateable value. Many homeowners are either over-insured or under-insured because they have not reviewed their sum insured for years.

Over-insurance means you are paying for coverage you do not need. Under-insurance is even more problematic, as you may face a shortfall if you need to rebuild. Use your insurer's online calculator or get a professional rebuild cost estimate to ensure accuracy.

5. Shop Around Annually

At renewal, compare available quotes and policy wording rather than assuming loyalty or switching will be cheaper. Use the same disclosed property details and comparable cover inputs.

• Ensure you are comparing like-for-like coverage
• Check excess levels are the same
• Look at exclusions carefully, not just the headline premium
• Consider using an insurance broker who can access multiple providers

6. Pay Annually Instead of Monthly

Payment-frequency costs vary. Ask for the total amount payable under annual and instalment options, including disclosed fees or charges, and choose only a schedule you can meet without financial strain.

7. Maintain Your Property Well

Policy wording commonly distinguishes insured sudden events from wear and tear or gradual damage. Maintain the property for safety and loss prevention, disclose relevant changes, and ask how a known defect or planned work affects cover rather than assuming a premium reduction.

8. Consider What You Actually Need

Review your policy inclusions carefully. Check optional benefits, limits and exclusions against the losses you need the policy to respond to. Removing a benefit may lower a quote but also removes or narrows protection, so obtain the revised terms in writing.

However, be cautious about stripping coverage too aggressively. The goal is to eliminate waste, not essential protection.

9. Ask About Available Discounts

Ask the insurer or broker which pricing adjustments you are eligible for, their conditions and whether they continue at renewal. Do not state an affiliation or claims history inaccurately to obtain a quote.

10. Understand the Natural Hazards Commission Levy

A home policy that includes fire insurance generally includes the statutory Natural Hazards Insurance levy and access to NHCover. The Natural Hazards Commission says the levy has a current maximum of $480 plus GST per year; check the levy shown on each quote and compare the private policy cover as well.

While reducing premiums is worthwhile, do not compromise essential coverage to save money. Being under-insured when disaster strikes is far more expensive than paying slightly higher premiums. The cheapest policy is not always the best value.

Taking Action

Start by reviewing your current policy and understanding exactly what you are paying for. Then work through this list systematically, identifying which strategies apply to your situation. Any saving must be established from actual like-for-like quotes; it may be small, absent or accompanied by reduced cover or a higher claim-time cost.

Home insurance is essential protection for what is likely your largest asset. The goal is not to minimise your premium at all costs but to find the right balance between adequate coverage and reasonable cost. A lower premium is not guaranteed, and only the policyholder can decide—using the written terms and, where useful, regulated advice—whether the resulting cover and claim-time costs are suitable.
