Can I Save on Car Insurance by Listing my Wife or Girlfriend as the Main Driver? NZ 2026

1. The Test

Identical 30-year-old, North Shore Auckland, NZ Full licence, 2013 Toyota Aqua, $9,205 sum insured, $500 excess, no claims, comprehensive cover, drivers under 25 excluded.

We ran two quotes through each insurer's own quote or estimate tool:

•  Quote A: Male as primary driver, female as additional driver.

•  Quote B: Female as primary driver, male as additional driver.

We changed nothing else. Same address, same car, same cover, same excess.

2. What 9 NZ Insurers Did

Ranked by saving from listing the female first, primary/secondary swap only:

*Note: Assurant explicitly asks which driver uses the car most. The cheaper female-primary quote was generated by listing the male as the secondary driver who uses the car less. So this saving is only legitimate if the female actually does drive the car more. If she drives more, she should be the primary driver in any case.

3. What This Actually Tells You

Three groups of insurers, three different rules.

Group 1: Same price either way (Cove, Tower, AMI, State, AMP, Autosure, MAS)

Seven of the nine insurers we tested charged the same regardless of which partner was listed first. Four of them (Cove, Tower, AMI and State) collected gender during the quote, but defaulted to the higher-risk profile in the rating, so swapping the labels didn't change the price. The other three (AMP, Autosure and MAS) didn't collect gender at all during the quote, so the question never even came up.

Group 2: Cheaper if female drives more (Assurant)

Assurant asks which partner drives more and prices accordingly. Saying the female drives more saved $155.76 a year, but only if she genuinely does. Tell Assurant the female drives more when the male is the actual main driver and you have misrepresented a material fact.

Group 3: AA Insurance, the outlier

AA was the only insurer in our test where simply listing the female as the primary driver and the male as secondary, without any question about who drives the car more, produced a cheaper quote. $50.04 a year. Both drivers were listed and disclosed. While ‘main driver’ is used during the quote process, we couldn’t find any definition of ‘main driver’ or ‘primary driver’ in the AA Comprehensive Car Insurance Policy document itself. We checked both wordings AA currently has in circulation, the May 2022 version (still linked from their policy documents page) and the April 2025 update.

Whether that saving holds up at claim time is the question worth thinking about. Both drivers are on the policy, but AA's policy does require you to give "full and accurate information" and to tell them about "a change to the drivers of your vehicle." If a claim arises and AA establishes the male was actually the dominant driver, they could argue you withheld material information. Our recommendation: call AA directly on 0800 500 213 to confirm they're comfortable with the listing before relying on the saving. Get the confirmation in writing if you can.

4. When It Crosses Into Fronting

Across every insurer in our test, the line is the same: the saving is legitimate if the named primary driver is the person who actually uses the car most. It's fronting if they aren't. The patterns claims teams look for:

•  One partner has had a recent at-fault claim or traffic conviction, and the other takes the policy in their name to keep the rate down.

•  A younger partner is the real main driver, but the older partner's name is on the policy to dodge the under-25 excess.

•  One partner is on a restricted or learner licence and is the main user, while the full-licence partner fronts to skip the inexperienced-driver excess.

•  Gender swapping. The higher-priced partner does most of the driving, but the lower-priced partner is named as primary to capture the cheaper quote on insurers that vary by gender.

Detection happens at claim time. If the named primary driver's job, address, and routine don't reasonably explain where and when the accident happened, claims teams start asking who actually drives the car. Once misrepresentation is established, NZ insurers can decline the claim, cancel the policy and treat it as if it never existed, refuse renewal, and flag the breach on the Insurance Claims Register where the major insurers can see it. Serious or clearly deliberate cases can be referred to police as obtaining by deception under section 240 of the Crimes Act 1961.

5. How to Add Your Partner to the Policy

If your partner drives the car at all, list them. It avoids the unlisted-driver excess that kicks in when an undeclared driver is involved in any kind of claim, whether that's a crash, a theft, or a windscreen chip on the motorway.

You'll need their full legal name, date of birth, licence type and number, years of driving experience, claims history (last five to seven years), and any convictions, suspensions, or significant demerit points. Most major NZ insurers let you add a driver through their app or portal in about ten minutes.

A note on excesses: adding a higher-risk partner (anyone under 25, on a restricted or learner licence, or with recent claims) will typically raise the premium and may add excesses. Some insurers also exclude all drivers under a certain age outright, so anyone under that age must be specifically declared, not just covered under the open-driver clause. For a deeper walk-through, see our Open vs Named Driver excess guide.

6. Where the Real Savings Actually Are

The most you can save by reshuffling who's named first on a single policy, across the nine insurers we could fully test, is around $50 to $156 a year, and only on two of them (maybe). The same Auckland 30-year-old female on identical cover was quoted between $92.85 a month (Assurant) and $162.10 a month (Tower) in our scan. That's a spread of $831 a year between the cheapest and most expensive insurers for the same policy. The cross-insurer spread is bigger than every label-swap saving combined.

According to the Q1 2026 Quashed Index, 81% of Kiwis who shopped via the Quashed Market Scan found a cheaper policy, saving $377 a year on average. Run the comparison first; reshuffle the labels second.

Frequently Asked Questions

Can I put my partner as the main driver on my car insurance in NZ?

Yes, if they genuinely drive the car most. The main driver is whoever uses the car the most often in a normal week.

Can the policy be in my name if my partner is the main driver?

Yes. The policy holder and the main driver do not have to be the same person on any major NZ insurer we've tested. The actual main driver still has to be named on the schedule, and any change in regular drivers has to be notified.

Will listing my partner as primary driver save me money?

It depends entirely on which insurer. Of the nine insurers whose online tools let you swap primary and secondary drivers, seven charged the same either way. Assurant priced based on which partner drove more, so listing the female as the more frequent driver saved $155.76 a year, but only if she genuinely is the more frequent driver. AA Insurance was the only insurer where simply changing the order produced a cheaper quote without any question about driving frequency, saving $50.04 a year. We recommend confirming with AA directly before relying on this.

Is fronting illegal in New Zealand?

Fronting is a misrepresentation that gives your insurer the right to decline the claim, cancel the policy, refuse renewal, and flag the breach to other insurers. In serious or clearly deliberate cases, it can be prosecuted as obtaining by deception under section 240 of the Crimes Act 1961.

Will my partner's bad driving record affect my car insurance if I'm the main driver NZ?

Yes. If your partner is a regular driver of the car (most NZ insurers define this as once a month or more), their licence history, claims and convictions feed into your premium even when you're the named primary driver. A clean record on your side doesn't cancel out a riskier one on theirs.
