How should we value two vehicles and choose excesses for a family motor policy?
For a New Zealand family motor policy covering two vehicles, the aim is to set each vehicle’s insured value and excess so that you are protected against a major loss without paying unnecessarily high premiums. Consumer Protection
1. Value each vehicle correctly
For each vehicle, decide whether agreed value or market value suits your situation. Consumer NZ
Newer, high-value, financed, rare, or modified vehicles:
Consider agreed value. This gives more certainty about the payout if the vehicle is written off or stolen, because the amount is agreed with the insurer for the policy period. Consumer NZOlder, common vehicles where replacement is straightforward:
Market value may be adequate and can reduce premiums. The payout is based on what the vehicle is worth immediately before the loss. Consumer Protection
To set a realistic value:
- Check current prices for the same make, model, year, kilometres and condition (for example, comparable dealer listings or private-sale listings).
- Include valuable extras such as:
- tow bars
- roof racks
- accessories
- approved modifications
- Avoid deliberately under-valuing a vehicle to save premium — you may not have enough money to replace it after a total loss. AJG
A practical approach for a two-car household:
- Main/family vehicle (SUV, people mover, newer car): usually insure close to its realistic replacement cost.
- Second vehicle (older commuter/runabout): consider whether comprehensive cover is still worthwhile compared with its value.
2. Choosing excesses
The excess is the amount you contribute when you make a claim. Generally:
- A higher excess = lower premium
- A lower excess = higher premium Consumer NZ
Choose an excess you could comfortably pay at short notice.
A common family approach:
- Primary vehicle: choose a lower or moderate excess because it is more likely to be used frequently and may involve more day-to-day claims.
- Secondary vehicle: a higher excess may make sense if it is worth less and you mainly want protection from a major accident or theft.
Example thinking:
- If a vehicle is worth $8,000 and the excess is $2,000, you are effectively self-insuring the first quarter of its value.
- If a vehicle is worth $45,000, a $1,000–$2,000 excess may be a smaller proportion of the risk.
3. Consider the household drivers
For a family policy, check:
- Who is listed as a driver (especially younger or inexperienced drivers).
- Whether there are additional excesses for certain drivers.
- Whether both vehicles are covered when driven by all family members who may use them.
4. Review the policy annually
Vehicle values change, especially with depreciation and changing used-car prices. Review:
- insured values
- excess levels
- driver details
- whether comprehensive cover still makes sense for an older vehicle
Agreed values generally need reviewing at renewal because the appropriate amount can change over time. AA Insurance
If you share:
- the make/model/year of both vehicles,
- approximate current values,
- whether either has finance owing, and
- who drives them (including any under-25 drivers),
I can help you work through a sensible value and excess setup for your situation.
