Banks Are Turning an LVR Speed Limit Into a Hard Stop

Bank representative discussing mortgage lending requirements with a borrower

Reserve Bank mortgage restrictions are designed as portfolio limits, not blanket minimum-deposit rules. As they become a permanent feature of the system, the question of who is accountable for their wider effects deserves an answer.

The Reserve Bank's loan-to-value ratio restrictions are often understood as simple minimum deposit rules. They are not. Under the current settings, banks can make up to 25 percent of new owner-occupier lending above 80 percent LVR, and up to 10 percent of new investor lending above 70 percent. The Reserve Bank describes these as a speed limit on the proportion of new mortgage lending banks can write at higher LVRs.

An owner occupier with less than a 20 percent deposit is not automatically prohibited by Reserve Bank rules, and nor is an investor with less than 30 percent equity. The Reserve Bank sets limits across a bank's overall lending portfolio. Individual banks then decide how, and whether, they use the flexibility available inside those limits.

The Reserve Bank rule and a bank's policy are different things

Banks remain responsible for deciding who they lend to, and they can adopt credit policies more conservative than the Reserve Bank requires, their own serviceability tests, valuation requirements and minimum equity levels. They may also choose to reserve their available higher LVR capacity for particular borrowers or circumstances. Those are legitimate commercial and risk decisions.

What’s important is that borrowers can tell whether a constraint comes from the Reserve Bank's regulatory settings or from the individual bank's own credit policy.

Telling an investor they “need 30 percent equity because of Reserve Bank rules” does not tell the whole story. A fuller explanation is that the Reserve Bank limits the proportion of investor lending a bank can write above 70 percent LVR, while the bank decides how it allocates that capacity and what additional criteria it applies. The outcome for the borrower may ultimately be the same, but the reason is not, and borrowers are entitled to know which one they are dealing with.

Exemptions, and a case where the rule was misread

The distinction becomes sharper still, because not all residential lending is captured by the restrictions. The Reserve Bank exempts several categories, including Kāinga Ora First Home Loans and certain refinancing, portability, bridging finance, property remediation, construction lending, and qualifying purchases of newly built homes. The new-build exemption exists deliberately, to keep credit flowing into new supply.

An exemption does not oblige a bank to lend, it must still be satisfied with the borrower's income, serviceability, security and overall risk.

However where lending qualifies for an exemption, the LVR restriction itself should not be treated as the reason to decline. We have seen this go wrong in practice. Lending staff at some banks declined finance at 80 percent LVR on new-build purchases on the basis that the developer, rather than the end buyer, sat earlier in the sale chain, treating that structure as if it removed the exemption.

Asked directly, the Reserve Bank confirmed that interpretation does not reflect its policy. It is a small, technical example, but it makes the general point concrete. The part of the housing pipeline the country most agrees it needs, new supply, was being slowed by a misreading of the very provision designed to protect it.

The regulatory ceiling is not a lending target

There is another useful piece of context. In its May 2026 Financial Stability Report, the Reserve Bank reported that less than 15 percent of new owner-occupier lending was above 80 percent LVR.

The permitted limit is 25 percent.

That does not mean banks should be lending up to the ceiling, demand, serviceability, valuations, borrower quality and individual risk appetite all shape how much higher LVR lending is actually written. But it does show the regulatory limit and the lending policies borrowers actually meet are not the same thing.

Institution level information about how each bank uses its LVR allowance is not generally available.

As a result, someone declined for higher LVR lending may have little way of knowing whether the determining factor was the Reserve Bank restriction, the bank's allocation of its available capacity, an internal credit policy, serviceability or valuation.

All can be legitimate reasons to decline. Greater transparency about which factor decided the outcome would improve borrowers' understanding of the market.

A temporary restraint has become permanent architecture

LVR restrictions were introduced in 2013, against a backdrop of rapidly rising house prices and increasing low deposit lending.

The macroprudential framework has evolved considerably since. The Reserve Bank now intends to maintain long run LVR settings through most of the economic cycle, tightening or loosening them as systemic risks change.

That effectively makes borrower based restrictions an enduring part of New Zealand's financial architecture, rather than an emergency response to an overheated market.

There are sound reasons for the approach. Highly leveraged borrowers are more vulnerable when prices fall, unemployment rises or rates increase, and a heavily exposed banking system can amplify a downturn. Financial stability matters to everyone. But permanent borrower based restrictions also have effects well beyond bank balance sheets.

They influence access to home ownership and residential investment, housing construction, household mobility, and the availability of finance secured against residential property.

Housing and the wider economy are closely connected

New Zealand should not rely on ever rising house prices as a source of prosperity. But neither should we pretend housing operates independently of the productive economy.

Housing is the largest asset held by many households and represents a substantial share of bank lending, and changes in housing wealth influence how people behave.

Reserve Bank research has estimated that, on average, a one dollar change in housing wealth is associated with roughly three cents of changed household consumption, with falling housing wealth having a stronger effect on spending than an equivalent increase.

Housing is also tied to small business finance. In its May 2026 Financial Stability Report, the Reserve Bank reported that around $5 billion of bank lending to small and medium businesses, excluding agriculture and commercial property, about 11 percent of that lending, was secured against residential property.

For many owners, the family home is the security behind working capital, equipment, an expansion, or the ability to survive a difficult trading period. Restrict access to housing credit and the effects do not stop at the front gate.

Who should be accountable for these settings?

As borrower based restrictions become permanent, one question can no longer be left blurred. Who is accountable for their wider economic effects?

Under the current framework the Reserve Bank holds operational responsibility for macroprudential policy as part of its financial stability mandate, while the Government sets broad expectations through the Financial Policy Remit.

There are genuine advantages to that. The Reserve Bank has real expertise in systemic risk, and there is good reason to insulate financial stability decisions from short term political pressure.

But LVR and debt to income restrictions now reach well beyond bank balance sheets, into home ownership, residential investment, construction, household spending and small business finance. Those are distributional choices, and they fall differently on different generations, regions and housing tenures.

My view is that where a settings regime has consequences this broad and has become permanent, final responsibility for it should sit with elected government, the body that answers for housing, growth and the wider economy at the ballot box.

That would not mean ministers approving mortgages or directing banks to lend. Banks would still assess income, serviceability, security and risk exactly as they do now. It would mean the broad boundaries around household credit are set by people accountable for the consequences, on published advice from the Reserve Bank and Treasury, with the Reserve Bank keeping the ability to tighten quickly in a genuine emergency.

Alongside that, a more transparent system would help everyone. Banks could report, at least quarterly and in aggregate, how much of their permitted higher LVR and higher DTI capacity they are actually using.

Where a loan is declined or additional equity required, the borrower could be told plainly which factor determined it, a Reserve Bank restriction, the bank's allocation of its capacity, its own credit policy, serviceability or valuation.

None of that weakens prudential regulation. It simply makes clear who is responsible for what.

Clarity would benefit everyone

New Zealand needs a resilient banking system, and it needs banks able to support creditworthy households, residential construction and viable businesses through the cycle.

Those goals are not mutually exclusive.

The Reserve Bank deliberately structures LVR restrictions as portfolio limits that leave banks some flexibility, and banks quite properly decide how that flexibility is used.

The important thing is that the line between regulation and a bank's own policy stays clear and that, as these restrictions become a permanent part of the financial architecture, someone accountable to the public owns their wider consequences.

Financial stability is essential. So is being honest about who is setting the rules that govern access to credit, and answerable for what they do to the wider economy.
