Mortgage + Insurance
Most New Zealand banks don't require you to have life insurance when you take out a mortgage. That means millions of homeowners are carrying hundreds of thousands of dollars in debt with no plan for what happens to their family if they're not there to pay it.
The legal reality
When you die, your mortgage becomes a debt of your estate. The bank doesn't write it off, pause it, or give your family time to grieve before acting. Their position is simple: the loan must be repaid.
If your estate has enough assets to cover the debt, the mortgage can be paid out from those assets. If it doesn't — or if repayments can't be maintained — the bank can take steps to recover what's owed.
This is the part most people don't think about. It's not a worst-case scenario that only happens to other families. It's the legal and financial default for every homeowner who doesn't have a plan in place.
What happens step by step
You pass away — the mortgage continues. Interest keeps accruing. Repayments are still due.
The bank notifies the estate — your executor (or administrator) takes responsibility for managing the debt.
The estate has options — pay out the mortgage from assets, transfer the loan to a surviving partner (if they qualify), or sell the property.
If repayments stop — the bank will issue a demand. If not resolved, they can appoint a mortgagee and force a sale.
The family has no veto — the bank's legal rights are clear. Financial need or personal circumstances don't override the loan contract.
How you own the property matters
The most common ownership structure for couples. When one owner dies, their share automatically passes to the surviving owner through the right of survivorship — it doesn't go through the estate.
BUT: the full mortgage debt transfers to the surviving partner. They now own the whole property — and owe the whole loan. If they can't afford the repayments alone, the problem is the same.
Each person owns a defined share (e.g. 50/50 or 70/30). When one dies, their share goes through their estate — to whoever is named in the will, or to the intestacy rules if there is no will.
The surviving owner doesn't automatically inherit the deceased's share. This can create complications where a co-owner ends up sharing the property with a stranger.
The entire property and the entire mortgage sit in the estate. The executor must manage both. Without sufficient other assets or insurance, the property usually has to be sold to repay the bank.
There is no partner to absorb the debt. The full outcome rests entirely on what the estate holds — and whether the estate can repay the bank without a forced sale.
What actually happens to families
The hardest thing about this situation is the timing. A family that has just lost someone is also being asked to make urgent financial decisions about their most important asset.
Without life insurance to clear the mortgage, the options are narrow:
In many cases, the honest answer is no. And when the answer is no, the property has to be sold — usually quickly, often at a price lower than it would achieve under normal market conditions, and at a time when the family is least equipped to manage the process.
A common scenario — no life insurance
Partner A passes away. They have a $600,000 mortgage held jointly with Partner B. Partner A was contributing $3,200 a month to the household. Partner B earns $72,000 a year — enough to cover the basics, but not the full mortgage repayment.
Partner B has three months before the bank begins formal recovery proceedings. They have to:
Life cover of $600,000 on Partner A's life would have cleared the debt on the day it was needed.
Your options
You don't need all three. But understanding each one helps you build a structure that actually works.
The primary solution
Pays a tax-free lump sum on death (or on terminal illness diagnosis). Used directly to pay off the outstanding mortgage — leaving your partner and family with no debt and ownership of the home.
How it works with your mortgage
You set the sum insured to at least match your mortgage balance. As you pay down the mortgage, your adviser can review whether the cover level should reduce (cheaper) or remain (to protect other family needs).
Best for
Anyone with a mortgage and financial dependants. This is the foundation of mortgage protection planning.
Watch out for
Setting the sum insured too low. Many people insure the mortgage balance but forget to account for income replacement, living costs, and children's education. Your adviser will help you model the full number.
The repayment safety net
Pays your mortgage repayment directly if you're unable to work due to illness or injury — or on death. Works at the same frequency as your loan (weekly, fortnightly, monthly).
How it differs from Life Cover
Life cover pays a lump sum once. Mortgage protection pays ongoing — it's designed to cover the repayment, not clear the debt. Often used alongside life cover, or as a standalone for borrowers on tighter budgets.
Best for
Homeowners whose immediate concern is keeping up with repayments if something goes wrong, rather than clearing the mortgage outright.
The most comprehensive approach
Combines life cover (to clear the mortgage on death) with income protection (to maintain payments if you can't work due to illness — the cause of most financial hardship, not death).
Why income protection matters for mortgage holders
You're far more likely to be unable to work for 3–12 months due to illness than you are to die in the next year. Without income protection, that period can quickly put your home at risk long before life cover would ever pay out.
Best for
Anyone with a mortgage who understands that the risk of disability is higher than the risk of death — and wants protection against both.
Working out the number
Worked Example — The Smith family
Calculation
This is a starting point, not a final answer. Every family's picture is different — your adviser will model the right number for your situation, income, and other assets.
Mortgage balance = minimum floor
Your outstanding loan is the non-negotiable baseline. Without at least this, your family loses the home. Everything above this is income replacement and lifestyle protection.
Decreasing vs level cover
Decreasing cover reduces each year as your mortgage reduces — cheaper, but only covers the debt. Level cover stays flat — covers both the mortgage and your other financial needs over time. Most families benefit from a combination.
Review it regularly
Life cover isn't set and forget. As the mortgage reduces, as kids grow up, as income changes — the number you need changes too. An annual review ensures you're not over-insured (paying too much) or under-insured (not protected enough).

"The gap between having a mortgage and having protection is a decision most NZ families don't realise they've made. If you have a home loan and no life cover, the bank has a plan for what happens. Your family deserves one too."
