Most homeowners can quote their CV. Far fewer know what it means for the money they could borrow, or the price they would get if they sold. The short answer: your CV is a rates number frozen on one date, often a year or more ago. Your total equity is your home’s current value minus what you owe. The amount you can borrow against is lower again, and depends on the lender’s valuation, its LVR limits, your income and your other debts. Those numbers can sit tens of thousands of dollars apart, and if you are selling to buy again, the sale price, not the CV, sets your next deposit.
This guide walks through what the CV is, how far it drifts from the market, how to estimate the equity you can use, and why the sale price matters more than the CV once you decide to move.
Councils must revalue the properties in their area at least every three years, and each council sets its own valuation date and release schedule. Auckland Council puts the definition plainly: the capital value is “the most likely selling price at the date of valuation.” The date is the important part. Auckland’s values are as at 1 May 2024 and were released to owners in June 2025. Christchurch’s are as at 1 August 2025, and notices went out from late February 2026 according to QV, which prepared them. Hamilton, Tauranga and Wellington each sit on their own cycle.
The values are set by mass valuation. QV and Opteon, the valuers councils use, compare sales of similar homes in the same area around the valuation date. Nobody walks through your house. Auckland Council’s own page says the revaluation is not intended for marketing, sales or any other purpose. It exists to split the rates bill fairly.
So a CV tells you roughly where your home sat in the market on one day, which may be one to three years ago. It says nothing about the renovation you finished since, the new build next door, or what happened to prices in your suburb this year.
Further than people expect, and the direction depends on where you live.
Opes Partners tracks sale prices against CV by district. In August 2026 homes in Grey District were selling about 22% above CV, Invercargill 21% above and Clutha 20% above. At the other end, Ōpōtiki was about 16% below CV, Stratford 11% below and Carterton 10% below. The spread comes down to timing. A district revalued at the top of the market carries high CVs into a flat period. One revalued at the bottom sees prices run ahead of its CVs.
Auckland is the clearest example. When the 1 May 2024 values landed, the average residential value was 9% lower than at the previous revaluation. Owners who had anchored on the old CV since 2021 found their equity had been overstated for three years.
Online estimators fill the gap between revaluations. HomesEstimate on homes.co.nz, OneRoof’s estimate and QV’s e-Valuer all update far more often than a council does. They are computer models, though, and on any single property they can miss by a wide margin. Treat them as a second opinion, not a price.
Start with the plain number. Your total equity is what your home is worth now minus your mortgage balance. On a $1 million home with a $600,000 loan, that is $400,000.
You cannot borrow against all of it. The Reserve Bank allows up to 25% of a bank’s new owner-occupier lending to exceed 80% LVR, and up to 10% of new investor lending to exceed 70%. Those settings were confirmed at its August 2026 review. That does not guarantee anyone a low-deposit loan. Banks apply their own deposit, income, affordability and credit criteria on top, and most owner-occupier top-ups are assessed against the 80% line.
So the working estimate is:
Indicative usable equity = 80% of the lender’s accepted property value minus the current loan balance.
It is a starting point, not a borrowing limit. Debt-to-income restrictions and the lender’s servicing tests can cut what you can borrow even when the equity sum looks comfortable.
Here is the estimate on a $1 million home with a $600,000 mortgage, depending on which value the lender accepts.
| Scenario | Accepted value | 80% of value | Loan | Indicative usable equity |
|---|---|---|---|---|
| CV taken at face value | $1,000,000 | $800,000 | $600,000 | $200,000 |
| Valued 5% under CV | $950,000 | $760,000 | $600,000 | $160,000 |
| Valued 4% over CV | $1,040,000 | $832,000 | $600,000 | $232,000 |
A 9-point swing in the accepted value is a $72,000 swing in the starting estimate. That is the difference between a renovation that fits and one that does not, or a deposit that clears the 20% line for the next home and one that falls short.
The lender decides which value applies. A lender may accept an electronic valuation, use its own estimate, or request a registered valuation from a valuer who inspects the property. The method depends on the lender, the property and the proposed loan. Whichever it is, that number sets the sum, not your CV. Our refinancing guide covers when a restructure makes sense, and a broker can tell you before you apply which method your lender is likely to use.
For owners who sell and buy in the same move, the mortgage on the next home is built on what they clear from the sale: the price on the contract, minus the loan they repay, minus selling costs. The CV plays no part in that sum. The price does, and the price varies with who sells the house.
AgentWise, a New Zealand service that compares local real estate agents on their sales records, measures every agent on average sale price versus CV, because the CV is the one benchmark every property has. Across 130 of its reports this year in which every agent compared had at least five confirmed-price sales, the highest and lowest sale-price-to-CV records among the agents compared differed by a median 4.3 percentage points. In 44% of those reports the gap was five points or more. The highest record in a typical report sat 4% above CV; the lowest sat 0.5% below.
On a $1 million home, 4.3 points is about $43,000. That is a comparison of historical results, not a promise that one agent will get $43,000 more for a particular property. An agent’s average is shaped by the homes they happen to sell, when they sold them, how they were marketed and how motivated the vendors were, and a small sample can flatter or punish. In 20 of those 130 reports even the highest record sat below CV, usually in districts where the whole market sits under its valuation.
The comparison is still worth making, because it is measured the same way for every agent in the same area, which is more than an appraisal on a coffee table can say. For a seller who needs a 20% deposit on the next home, a few points either way on the sale price is the difference between clearing that line and falling short of it.
Owners who sell and buy at the same time get caught out when they plan around the CV. A cleaner order looks like this.
Check the date on your CV first, and read it as history. Get a HomesEstimate or OneRoof figure as a rough current marker. If you will be borrowing on the next place, talk to a broker before you list, so you know which valuation method your lender is likely to use and how much usable equity you can count on. Then compare agents on their records rather than on who calls first, because the sale price sets the deposit. Bridging finance is exempt from the Reserve Bank’s LVR restrictions, but the lender will still assess how the bridging loan will be repaid. Depending on the application, it may want an unconditional sale, a credible sale plan, or enough income and equity to carry both properties for a while. Our list of five questions to ask before choosing a mortgage broker is a good place to start that conversation.
Your CV is a fair way to split the rates bill. It is a poor way to plan a mortgage or a sale. Work from what a lender will accept the home is worth now, treat the 80% sum as a starting estimate, and if you are selling, compare agents on their sale-price-to-CV records before you list, because the price you clear sets the next deposit. If you want a broker who will tell you which valuation your lender will accept before you commit, get started with Best Mortgage Brokers and we will match you with a vetted adviser in your region.
Is the CV the same as the RV or GV?
Yes. Capital value, rateable value and government valuation are the same figure. Land value and improvement value are its two parts.
Will the bank lend against my CV?
Not directly. Lenders use an electronic valuation, their own estimate or a registered valuation. The CV may be one input, but it is rarely the deciding number.
How often does the CV change?
At least every three years, plus a supplementary valuation when you subdivide, build or get a consent that changes the property.
Can I object to my CV?
Yes, within the objection window after a revaluation. Councils warn that an objection can move the value up as well as down, and it will not change what a buyer pays.
