CCCFA and Mortgage Affordability NZ — How Responsible Lending Rules Affect Borrowing

Updated

The Credit Contracts and Consumer Finance Act 2003 (CCCFA) is the primary legislation governing how New Zealand lenders assess mortgage applications. Its purpose is to protect borrowers from being put into unaffordable debt — but its 2021 amendments created significant controversy for making the mortgage approval process significantly harder for many borrowers. Understanding what CCCFA requires helps you prepare for the scrutiny lenders will apply.

Quick answer

CCCFA requires NZ lenders to make reasonable inquiries into your income, expenses, and existing debts before lending. From December 2021, this led banks to scrutinise every line of applicants' bank statements. Subsequent reforms (June 2022, March 2023) eased some requirements, but lenders still conduct detailed affordability assessments. Your lifestyle spending does affect your borrowing capacity.

What CCCFA Requires of Lenders

The CCCFA creates a statutory obligation on lenders to:

  1. Make reasonable inquiries into the borrower’s income, assets, expenses, and existing liabilities
  2. Verify the information provided (including through bank statements, payslips, and credit checks)
  3. Assess whether the loan will be affordable over its term under a range of scenarios (including stress-tested interest rates)
  4. Conclude that the loan is not “unsuitable” for the borrower before lending

Prescribed debt-to-income (DTI) ratio: Since July 2024, lenders are also subject to RBNZ’s DTI limits (6× for owner-occupiers, 7× for investors) as a separate macro-prudential tool. The CCCFA operates alongside but independently of DTI rules.

The 2021 Controversy

In December 2021, new CCCFA regulations came into force. These regulations:

  • Required banks to verify actual living expenses from bank statements (rather than using benchmarks)
  • Created significant uncertainty about which expenses could be discounted or which were unavoidable
  • Led banks to apply extremely conservative assessments: Netflix subscriptions were declined, regular takeaways flagged, charitable donations scrutinised

The result was a sharp increase in declined applications and a public backlash. The Commerce Commission, which enforces the CCCFA, became active in prosecuting lenders for non-compliance.

The 2022 and 2023 Reforms

Following widespread criticism, the government made amendments:

June 2022 amendments:

  • Clarified that lenders can use benchmarks for everyday expenses rather than scrutinising every transaction
  • Removed requirements that had led to overly conservative assessments
  • Made CCCFA more proportionate for less complex loans

March 2023 amendments:

  • Excluded some categories of short-term consumer credit from the most onerous requirements
  • Adjusted regulations to reflect that reasonable inquiry doesn’t require exhaustive investigation of every expenditure

2024 onwards: The CCCFA framework has stabilised. Banks continue to conduct affordability assessments but are no longer applying the extreme scrutiny of the December 2021–June 2022 period.

What Banks Assess in 2026

Despite reforms, lenders continue to conduct meaningful affordability assessments. Here’s what they examine:

Income

  • Employment income (payslips, employment letter)
  • Self-employment income (2 years of financial statements and IR3 returns)
  • Rental income (typically assessed at 75% of gross rent)
  • Other income (investment dividends, ACC, supported living payment)

Expenses

Banks assess total living expenses — either from your actual bank statements or against benchmark figures (the higher of the two approaches). Categories typically assessed:

  • Housing costs (rent if applicable, council rates, insurance)
  • Food and groceries
  • Transport (fuel, registration, WOF, public transport)
  • Health and personal care
  • Utilities (power, gas, internet, phone)
  • Education
  • Entertainment and dining
  • Regular subscriptions and memberships
  • Minimum repayments on credit cards, loans, hire purchase

Liabilities

  • All existing loan balances and repayments
  • Credit card limits (not just balances — available credit counts as a commitment)
  • BNPL (buy now pay later) facilities
  • Ongoing financial obligations (child support, maintenance)

How CCCFA Affects Your Borrowing Capacity

CCCFA’s affordability assessment can reduce your effective borrowing capacity compared to a pure DTI calculation:

Stress-test rate: Banks assess whether you can still afford repayments if interest rates rise to 8%–9% (approximately 2.5%–3.5% above current rates). Repayments at this stress-tested rate must be affordable from your declared income minus declared expenses.

Example:

  • Household income: $140,000
  • Household expenses (bank-assessed): $65,000/year
  • Net surplus: $75,000/year = $6,250/month
  • Repayments at stress-test rate (8.5%) on a $700,000 loan: ~$5,400/month
  • Result: Passes — surplus covers stressed repayments with buffer

If expenses were higher (e.g., $85,000/year), the same income would produce a tighter result or a decline.

Practical Implications: Preparing Your Application

3 months before applying:

  • Reduce unnecessary subscriptions and credit card limits
  • Pay off or close BNPL accounts (Afterpay, Laybuy, Zip)
  • Avoid large unexplained cash withdrawals
  • Don’t open new credit accounts

At application:

  • Provide honest, accurate information — CCCFA penalties for lenders who don’t make reasonable inquiries incentivise thorough checking, and providing false information is a separate offence
  • Explain any irregular or one-off expenses clearly
  • Consolidate smaller debts before applying where possible
  • Provide 3 months of bank statements showing income and expenses clearly

CCCFA Enforcement

The Commerce Commission enforces the CCCFA and has prosecuted several lenders for:

  • Failing to make reasonable inquiries
  • Lending where repayments were clearly unaffordable
  • Applying excessive fees

Consumers who believe they were lent to irresponsibly under CCCFA can complain to the Financial Services Complaints Limited (FSCL), the Banking Ombudsman, or the Commerce Commission.

Frequently Asked Questions

What is the CCCFA and why does it affect mortgages?

The Credit Contracts and Consumer Finance Act requires lenders to make responsible lending decisions — ensuring borrowers can afford the debt being extended to them. For mortgages, this means banks must verify income and expenses and stress-test repayments before approving a loan.

Did the CCCFA make it harder to get a mortgage?

The December 2021 regulations did significantly tighten approvals — banks became extremely conservative about living expenses. Subsequent reforms in June 2022 and March 2023 eased some of these restrictions. The framework in 2026 is more proportionate than its 2021 peak.

Does Netflix or takeaways affect my mortgage application?

Post-2022 reforms, banks are no longer required to scrutinise individual discretionary transactions. However, if your total lifestyle spending is very high relative to your income, it may affect the surplus used to service the mortgage. Extreme spenders may benefit from demonstrating reduced spending in the months before application.

What interest rate do banks use to stress-test NZ mortgage applications?

Banks typically add 2.0%–3.0% to the current lending rate to produce the stress-test rate. In 2026 with rates around 5.50%, stress tests are typically conducted at 8.0%–8.5%.

Can I complain if a bank wrongly declined my mortgage application?

You can complain to the bank’s internal dispute resolution process first. If unresolved, escalate to your bank’s external dispute resolution scheme — the Banking Ombudsman for major banks. For CCCFA-specific issues, the Commerce Commission also accepts complaints.
