A low credit score doesn’t automatically disqualify you from getting a mortgage in New Zealand — but it changes where you apply and what rate you’ll pay. Non-bank lenders specialise in exactly this situation, and a mortgage broker is the most efficient way to find them.
You can get a mortgage with bad credit in NZ through non-bank lenders such as Liberty Financial, Resimac, Avanti Finance, and First Mortgage Trust. Expect interest rates 1%–4% above major bank rates and a typical deposit requirement of 20%–30%. A mortgage broker is essential — non-bank lenders rarely advertise publicly.
What Counts as “Bad Credit” for a NZ Mortgage?
NZ credit scores are issued by Equifax (scale 0–1,000) and illion (0–1,200). There is no formally published minimum for mortgage approval, but in practice:
- Major banks (ANZ, ASB, BNZ, Westpac, Kiwibank): Generally approve borrowers at 600+ on the Equifax scale; most decline below 500
- Non-bank lenders: Will typically consider borrowers in the 400–550 range depending on the nature of the adverse information
- Sub-400 or recent serious defaults: Lending is still possible in some cases, but at significantly higher rates and with a larger deposit
Beyond the number, banks look closely at the type of credit event:
| Event | Severity | File Duration |
|---|---|---|
| Isolated missed payment (paid) | Low–moderate | 2–5 years |
| Default (unpaid) | High | 5 years |
| Default (paid) | Moderate | 5 years |
| Court judgment / debt order | High | 5 years |
| Bankruptcy | Very high | 4 years after discharge |
| Pattern of multiple missed repayments | High | 5 years |
Recency and context matter significantly. A single missed bill from four years ago due to a genuine oversight is treated very differently from a pattern of defaults in the past 18 months.
Non-Bank Lenders for Bad Credit Mortgages in NZ
The following lenders specialise in borrowers who don’t qualify at major banks. Rates and policies change — a mortgage broker will have current terms.
Liberty Financial One of the largest non-bank mortgage lenders in NZ. Offers residential mortgages across multiple risk tiers. Borrowers with credit impairment, recent defaults, or irregular income structures are assessed on a case-by-case basis. Rates typically 6.5%–9.5% depending on credit profile and LVR.
Resimac Australian-owned with a significant NZ residential book. Works with self-employed borrowers and those with adverse credit history. Tiered rate structure based on assessed risk.
Avanti Finance NZ-owned non-bank lender with a track record of working with borrowers in non-standard situations. Rates typically 6.5%–8.5%.
First Mortgage Trust NZ-owned and well established. Lends on residential and commercial property. LVR caps are typically tighter — often 65%–70% maximum for adverse credit situations.
Pepper Money Active in the NZ market for residential borrowers with credit challenges, part of an Australian-based non-bank group with NZ-specific lending policies.
These lenders do not widely advertise to consumers directly. Access is typically via a mortgage broker with active accreditation across multiple non-bank lenders.
What Deposit Do You Need with Bad Credit in NZ?
At major banks, 20% is the standard minimum deposit (80% LVR). For bad credit borrowers through non-bank lenders, expect:
- 20% deposit: Possible for isolated, older adverse events with otherwise strong income
- 25%–30% deposit: More commonly required for recent defaults or multiple adverse events
- 35%+ deposit: May apply to more significantly impaired credit profiles
A larger deposit reduces the lender’s risk and typically results in a lower rate tier.
Improving Your Mortgage Prospects with Bad Credit
1. Know your credit file before applying Get your free Equifax report at equifax.co.nz and your illion report at creditsimple.co.nz. Check both for errors — you can formally dispute incorrect information with each bureau. A corrected error can meaningfully improve your score.
2. Settle outstanding defaults An unpaid default carries more weight than a paid one. If you can settle before applying, do so. A paid default still remains on file for 5 years, but lenders view it more favourably than an unresolved one.
3. Reduce credit card limits Banks and non-bank lenders both count your total credit card limits (not just balances) in their affordability assessment. Reducing limits before applying improves your DTI calculation without affecting your actual ability to repay.
4. Build a savings history Consistent deposits into a savings account over 3–6 months signal financial stability, even when a credit score is low. Regular savings behaviour is a positive indicator for lenders assessing the overall picture.
5. Wait and repair where possible Defaults fall off your credit file after 5 years. If you are 2–3 years into that period with no new adverse events, waiting may deliver a materially better rate than applying now. Use that time to build equity and savings.
Using a Mortgage Broker for Bad Credit Applications
A broker is essential for bad credit mortgage applications for several reasons:
- Brokers hold active accreditation with non-bank lenders who do not deal directly with the public
- Multiple applications at different banks generate multiple hard credit inquiries, each reducing your score. A broker submits one well-structured application to the most suitable lender
- Non-bank lenders have complex risk-tiered pricing that requires specialist knowledge to navigate effectively
Most NZ mortgage brokers are paid by the lender rather than the borrower — broker services are typically free to you.
The True Cost of a Bad Credit Mortgage — and the Path to a Better Rate
The rate premium on a non-bank mortgage adds up materially. On a $600,000 mortgage over 30 years:
| Rate | Monthly repayment | Total interest |
|---|---|---|
| 5.8% (major bank standard) | $3,529 | ~$670,000 |
| 7.5% (non-bank mid-tier) | $4,196 | ~$910,000 |
| 9.0% (higher risk tier) | $4,828 | ~$1,138,000 |
The optimal strategy is to qualify with a non-bank lender, maintain a clean repayment record for 12–24 months, and then refinance to a major bank at standard rates. Most borrowers in this situation successfully transition within 2–3 years, saving several hundred dollars per month.
Frequently Asked Questions
Can I get a mortgage with bad credit in NZ?
Yes — through non-bank lenders such as Liberty Financial, Resimac, Avanti Finance, and First Mortgage Trust. Rates will be 1%–4% above major bank rates and a larger deposit of 20%–30% is typically required. A mortgage broker is the most efficient route to these lenders.
How long does a default stay on my NZ credit file?
A default stays on your NZ credit file for 5 years from the date it is recorded, whether paid or unpaid. A paid default is viewed more favourably, but both remain for the full period.
What credit score do I need for a mortgage in NZ?
Major banks typically look for a score of 500–600+ on the Equifax scale. Non-bank lenders may consider borrowers with scores from 400 depending on the specific events and overall financial picture. There is no single published minimum — lenders assess holistically.
Will applying to multiple banks hurt my credit score in NZ?
Yes. Each formal mortgage application results in a hard credit inquiry that temporarily reduces your score. Applying to 4–5 banks at once can meaningfully worsen your position. A mortgage broker submits one structured application to the most suitable lender, avoiding this.
Can I refinance to a major bank after a non-bank mortgage?
Yes — this is the standard path. After 12–24 months of clean repayment history with an improved credit profile, most borrowers can refinance to a major bank at standard rates, saving hundreds of dollars per month.
