Working out your real net worth sounds simple. Add up what you own, subtract what you owe. The catch is that for most NZ households, no one actually sits down to do it until something forces the question — tax time, a mortgage application, or a meeting with an accountant.
Your net worth is the number that tells you whether the past year has actually moved you forward, or whether the income increases have just been going out the door. The trouble starts the moment you try to work it out manually — because that's when you realise this is a software problem.
Net worth sits across a dozen places in most NZ households. Bank accounts, a joint account, a KiwiSaver in one provider, a second KiwiSaver for your partner in another, a Sharesies portfolio, maybe a Hatch account, a term deposit somewhere, a mortgage or two, a credit card or three, and the value of whatever property you own. Adding them up on a spreadsheet is how most people start. Keeping them up to date over time is why most people stop.
This is what a NZ net worth tracker should actually do in 2026, and why SortMe was built to do it.
What "net worth" actually is
Net worth is what you own minus what you owe. That's it.
Assets: bank account balances, term deposits, KiwiSaver balances, managed fund holdings, direct share and ETF holdings (Sharesies, Kernel, NZX direct), cryptocurrency if you hold it, property values (main home, rentals, holiday home), the equity in any business you own, vehicles if they're worth noting.
Liabilities: mortgages (main and rentals), credit card balances, car loans, personal loans, Afterpay or other BNPL balances, student loans (in NZ, at 0% for residents, but still a liability), business debt if you're personally liable.
Net worth is your total assets minus your total liabilities. Most NZ households have a net worth that sits somewhere between NZ-median household wealth of around four hundred thousand(1) and several million for established multi-property owners.
Why you actually need to track it
Three reasons that matter.
Reason 1: tax time and mortgage applications. Accountants and mortgage brokers both ask. If you have a live number, the conversation is five minutes. If you don't, it's a folder of statements and two weeks of email back-and-forth.
Reason 2: concentration risk. The typical NZ household has a heavy share of net worth in residential property(2). That is not automatically wrong, but it is information — and if 90% of your wealth is in one house in one city, you should at least know that number before you make any decisions about KiwiSaver funds, shares, or further property.
Reason 3: momentum. Net worth moves up or down. Tracking it over time tells you whether your household is actually getting ahead, or whether the income increases are going out the door as fast as they come in. This creates encouragement and momentum.
What a NZ net worth tracker should do
Four things.
Connect to every major NZ bank automatically. Manual entry is the reason most spreadsheet attempts fall over. Your balances change every day; your tracker should read them, not wait for you to type them.
Pull KiwiSaver and investment balances. For most established households, property equity is the headline number — but KiwiSaver, Sharesies, Kernel, InvestNow, and managed funds make up the second tier of the balance sheet, and combined they're often six figures or more. None of it shows up in your bank app. A tracker that misses these accounts is under-counting a meaningful slice of your net worth.
Handle property values. You bought the house for $900k in 2016; it's worth $1.4m now. A tracker that doesn't let you update (or estimate) property value is under-counting your net worth.
Track liabilities at live balances. Your mortgage balance changes every fortnight. Your credit card balance changes every week. A snapshot from six months ago is worse than useless — it makes your net worth look higher or lower than it is.
SortMe does all four. Bank and KiwiSaver connections run through Akahu, NZ's open-banking provider(3). Property values can be entered manually or estimated from CoreLogic data. Mortgages and credit cards are pulled live.
How SortMe's net worth view works
Connect your accounts and the net worth view compiles automatically:
- Total assets, broken down by category (cash, KiwiSaver, shares, property, other)
- Total liabilities, broken down by category (mortgage, credit cards, other debt)
- Net position (the number that actually matters)
- Trend over time — how the number has moved
The day-one view typically surprises people in two ways. The first is that the KiwiSaver balance is bigger than they remembered. The second is that the concentration in property (for households who own) is higher than they'd assumed.
Both are useful. The KiwiSaver surprise often triggers a conversation about whether the fund type is right. The property concentration surprise often triggers a conversation about diversification.
The first time most of our users see their real net worth in SortMe, the number is meaningfully different from what they had in their head. Sometimes higher, because they'd forgotten how much is in their KiwiSaver. Sometimes lower, because the mortgage balance on the old spreadsheet was out of date. That gap between what you think you're worth and what you actually are is the first thing a useful net worth tracker should surface.
The practical next step
If you've never seen your real net worth, knowing the number is worth 20 minutes of setup. If you already track it in a spreadsheet, the question is how much time you spend maintaining that — and whether automating the maintenance is worth $45/month.
