When refinancing makes sense, what the all-in maths actually look like, and the break costs and re-registration fees that quietly swing the answer either way.
Indicative only. Why we say this
TL;DR
Refinance economics
The illustrative table below shows when a refinance commonly clears the cost of switching, on a typical NZ business term loan. The figures are indicative, computed on standard amortisation, and assume break costs are a function of remaining term and rate-cycle position.
| Scenario | Indicative gross saving | Indicative switching cost | Indicative net outcome |
|---|---|---|---|
| $100K, 2 yrs left, 1.0 pt drop, end of fixed term | ~$1,400 interest | ~$1,200 (estab + PPSR + legals) | Marginal, often near break-even |
| $250K, 3 yrs left, 1.0 pt drop, mid-fixed (rates fell) | ~$5,500 interest | ~$3,500 to $6,500 (incl. break) | Often net negative on rate alone |
| $250K, 3 yrs left, 1.0 pt drop, end of fixed term | ~$5,500 interest | ~$2,000 (estab + PPSR + legals) | Indicatively net positive |
| $500K, 4 yrs left, 1.5 pt drop, end of fixed term | ~$22,000 interest | ~$4,500 to $7,500 | Indicatively strongly net positive |
| $80K alt-lender short-term, 14 mo left, refi to bank | Variable (rate gap can be 8 pts+) | Often heavy early-repayment fee on origin loan | Highly file-specific, indicatively net positive when bank takes the file |
| Multi-facility consolidation, 3 facilities, $300K total | Indicatively $4,000 to $9,000 admin + interest | ~$2,500 to $5,000 (re-registration on each) | Often net positive on cash-flow grounds even when rate-flat |
Indicative figures on illustrative scenarios. Break costs and establishment fees vary by lender. Subject to the lender's assessment.
Refinance triggers
Most refinance conversations land on one of these five triggers. The trigger drives which lenders are likely to compete for the file and how the maths shapes up.
01
Wholesale rates have dropped since the loan was written, and the existing rate now sits well above current pricing for an equivalent borrower. Most common after an OCR easing cycle. The refinance maths depends heavily on whether the existing loan is on a fixed or floating structure and how much fixed term remains.
02
The borrower has 18 to 36 more months of trading history, profitability has stabilised, and the credit story is materially stronger than at original application. A loan written when the business was 18 months old typically prices very differently to one written when it has reached 4 years of clean trading.
03
The borrower now has equity in commercial property, an unencumbered fleet, or owns the trading premises outright. Security shifts an unsecured loan into a secured product, where indicative pricing is typically 2 to 5 percentage points lower for an equivalent amount and term.
04
The original loan was structured short (commonly 18 to 24 months) for cash-flow reasons, and amortisation is now tight. A refinance into a longer term reduces monthly repayment, sometimes at a higher headline rate, which can suit a business in a growth phase even where total interest rises.
05
A business has accumulated 3 or more facilities (a term loan, an overdraft, asset finance, sometimes an alternative-lender top-up) at different rates and reset dates. A consolidation refinance into a single facility often improves administrative load and total cost, even where the headline rate is similar to the weighted-average existing rate.
06
Less commonly, the existing lender has exited the segment, withdrawn a product, or altered terms at reset. Some alternative lenders that were active in the NZ SME market in 2020 to 2022 have narrowed their books. A refinance is sometimes initiated by the lender rather than the borrower.
Same lender vs new lender
A rate review with the existing lender is the lower-friction path. No new application, no new security registration, no break costs (because the contract continues), and a relationship manager who already knows the file. The trade-off is rate movement, which is typically smaller than what a competitive refinance can achieve.
In our experience across NZ business banking, a rate review at anniversary on a strong file commonly returns 0.25 to 0.75 percentage points of improvement, sometimes more where a written competitor offer is in hand. Rate reviews on weak files or new accounts commonly return little or nothing. The lever is the credible threat of leaving, not the relationship.
Rate reviews are most productive when the borrower has 12+ months of clean trading on the loan, no recent arrears, and the lender is competing against a real offer rather than a hypothetical move. A formal letter from a competing NZ lender, on the same loan structure, materially shifts the conversation.
A refinance to a new lender opens the full market and commonly delivers a larger rate movement, but it carries the cost stack of a new loan: new establishment fee, new PPSR registrations, new General Security Agreement (where applicable), legal fees on any property security, and break costs on the existing loan if it is on a fixed term that has not ended.
The all-in switching cost on a typical NZ small-business refinance commonly lands between $1,500 and $6,000 before break costs, depending on amount, security type, and whether legal work is required. Larger commercial-mortgage refinances can run materially higher, particularly where multiple property securities are involved.
The strongest refinance candidates are loans approaching the end of a fixed period (where break costs fall to zero), or floating-rate facilities (where break costs are typically nil). Mid-fixed-period refinances on contracts written at low historical rates are commonly uneconomic, because the break cost reflects the lender's loss against current higher wholesale rates.
Context
Break costs (sometimes called early-termination fees, early-repayment costs, or prepayment fees) on NZ fixed-rate business loans are typically calculated on the lender's actual loss formula. The lender funded the fixed-rate loan by buying matching fixed-rate funding from the wholesale market. When the borrower repays early, the lender is left holding wholesale funding that no longer matches a loan, and the lender reinvests the repayment at current wholesale rates.
Where current wholesale rates are below the rate at which the loan was written, the lender takes a loss on reinvestment, and the break cost passes that loss to the borrower. Where current wholesale rates are at or above the original rate, the lender breaks even or gains on reinvestment, and break costs commonly fall to zero or near zero. This is the same mechanism as on residential fixed-rate home loans in NZ.
The practical implication is that break costs are inversely correlated with the rate-cycle benefit of refinancing. The same OCR easing cycle that makes a refinance attractive also drives break costs higher. The two effects partially offset, which is why end-of-fixed-period and floating-rate facilities are commonly the strongest refinance candidates.
On alternative-lender short-term loans (typically 6 to 24 months), the structure is often different. Many of these contracts carry a fixed total interest charge, sometimes called a factor or buy rate, which is payable in full regardless of when the loan is repaid. An early payoff in month 4 of a 12-month loan commonly does not reduce the interest owed, making early repayment economically equivalent to running the loan to term. This is one reason alternative-lender short-term debt is poorly suited to refinancing mid-term, and is more commonly retired at the contract end.
The lender's loan documentation sets out the exact break-cost formula. The accountant or finance specialist is the right person to confirm the calculation in any specific case before a refinance decision is made. Lenders are required under the Credit Contracts and Consumer Finance Act 2003 (where it applies) and under fair-dealing obligations under the Financial Markets Conduct Act 2013 to disclose the break-cost methodology, though business lending sits largely outside the consumer-credit framework of the CCCFA.
Switching cost stack
The switching cost stack varies by loan type and security. The table below is an indicative breakdown of components for an unsecured-to-secured refinance from an alternative lender to a major bank, on a $250K loan. Actual figures depend on the lender and loan structure.
| Component | Typical range | When it applies |
|---|---|---|
| Establishment fee on new loan | $1,250 to $3,750 (0.5% to 1.5% of $250K) | Charged on every new bank or alternative-lender loan |
| Break cost on existing loan | $0 to $15,000+ | Fixed-rate loans, mid-term, when wholesale rates have fallen |
| Early-repayment fee (alt-lender short-term) | 0% to 100% of remaining interest | Alternative-lender short-term loans with factor-rate structures |
| PPSR registration on new GSA | ~$16 per security | New General Security Agreement filed on PPSR |
| PPSR discharge on existing GSA | ~$8 per security | Existing security removed from PPSR after refinance |
| Mortgage discharge fee | $300 to $800 | Property-secured loans, charged by existing lender |
| New mortgage registration | $200 to $400 LINZ + legal | Property-secured loans, on the new lender |
| Legal fees | $1,500 to $5,000 | Property-secured or complex security structures |
| Valuation (property) | $800 to $2,500 | Property-secured refinances commonly require fresh valuation |
| Account closure fee on existing loan | $0 to $250 | Some alternative lenders charge a closure fee separately |
Indicative ranges. Actual fees depend on the lender, loan structure, and security. Subject to the lender's and the legal adviser's confirmation.
Worked scenarios
Indicative figures on illustrative borrowers. The numbers in each scenario are based on the inputs shown.
Plumbing contractor, 6 years trading, $1.2M turnover, owns two utes outright
In this scenario, the business carries a 36-month bank term loan of $80K (24 months remaining, 11.5% fixed, written at OCR peak) and an alternative-lender working-capital facility of $45K (10 months remaining, 22% factor rate). Combined monthly servicing is around $4,800.
A consolidation refinance into a new 48-month secured term loan of $125K, with the utes registered on PPSR, is indicatively offered at 9.5% fixed. Estimated break cost on the existing bank loan is $1,400 (mid-fixed, but rates have fallen). The alternative-lender facility carries no early-repayment saving on the factor structure, so the remaining interest is paid out in full.
On these assumptions, the new monthly servicing falls to around $3,140, freeing approximately $1,660 a month in cash flow. Total interest over the new term is higher than continuing the existing facilities to their natural endings, but the cash-flow improvement and single-facility administration are the drivers of the decision.
Indicative figures
Cuba Street cafe, 4 years trading, $850K turnover, leasehold premises
In this scenario, the cafe holds a $180K unsecured term loan written 5 years ago at 13.5% with one month remaining on the 60-month term. The original loan financed a fit-out and equipment package. Trading has been consistent through the post-2024 rate cycle, with no arrears.
A like-for-like refinance, fresh 48-month unsecured loan of $180K (the balance is small, so the borrower is consolidating into a fresh top-up to refresh the espresso machine), is indicatively offered at 11.0%. End of fixed period means break costs fall to zero. Establishment fee is $1,800 (1% on $180K).
On these assumptions, the rate saving over the new 48-month term is around $9,600 against a hypothetical continuation at the old rate, against switching costs of approximately $1,950 including PPSR. The decision is indicatively net positive on rate alone, before the equipment top-up benefit.
Indicative figures
Engineering shop, 12 years trading, $3.5M turnover, owns commercial premises
In this scenario, the business carries a $400K unsecured term loan (24 months in, 36 months remaining, 12.0% fixed) used for a CNC equipment purchase. The trading premises in Sockburn have appreciated, and the business has equity not previously offered as security.
Refinancing the loan into a property-secured commercial mortgage, $400K over a fresh 60-month term at an indicative 7.5%, materially changes the unit economics. Break cost on the existing loan is estimated at $4,800 (rates have fallen since origination). New legal and valuation fees total approximately $4,200, plus $1,200 establishment.
On these assumptions, the rate move from 12.0% to 7.5% saves indicatively $34,000 in interest over the new 60-month term against a hypothetical continuation. Switching cost stack of approximately $10,200 leaves an indicative net saving of around $23,800. The longer term also reduces monthly servicing materially. The trade-off is that the property is now on PPSR and mortgage with the new lender.
Indicative figures
Pitfalls
These are the failure modes most often observed on NZ business loan refinances. Each is avoidable with the maths run before the application is signed.
A 1 percentage point rate drop on a $200K loan saves around $5,000 over 3 years. A 1.5% establishment fee on a $200K refinance is $3,000. Headline-rate comparison alone often hides the full cost. The total cost of credit number, computed over the new term, is the comparable figure.
Break costs on NZ fixed-rate loans can be requested as a written statement from the existing lender at any time before commitment. A refinance file built without a current break-cost figure is exposed to a settlement-day surprise that can shift the maths from net positive to net negative.
Alternative-lender short-term loans with factor-rate structures often carry punitive early-repayment outcomes, where the full contracted interest is payable regardless of payoff date. Refinancing these mid-term commonly destroys the rate saving. Running them to natural end is often the better path.
Refinancing a 24-month loan into a 60-month loan at the same rate roughly doubles total interest paid, even though the monthly repayment falls. Where the refinance is cash-flow-driven rather than rate-driven, the total-interest impact is the figure to anchor on.
On secured refinances, the old lender's GSA on PPSR and the new lender's GSA can overlap if discharge is not timed correctly. Most lenders on the new file will require sole-registered status before drawdown. The legal adviser is the right person to coordinate the discharge and registration sequence.
A new loan typically requires a fresh personal guarantee from the directors or owners. The PG on the existing loan is released on payoff. Where the directors' personal-credit position has changed since origination, the new PG may price differently or be declined, even where the business itself looks stronger.
Refinance process
01
A written break-cost statement is commonly requested from the existing lender 2 to 4 weeks before the proposed refinance date. Statements are typically valid for a short window (often 14 days) because wholesale rates move. The statement is the input to the refinance maths, not the published rate.
02
Like-for-like applications across multiple NZ lenders commonly return rate spreads of 1 to 4 percentage points on the same file. Major-bank, alternative-lender, and registered-bank options each have different speed-to-decision and pricing profiles. A specialist broker is often used to coordinate the comparison without the borrower personally carrying multiple credit-file enquiries.
03
The comparable figure is total cost of credit on the new loan over the new term, plus switching costs, against remaining cost on the existing loan over the remaining term, plus break costs. The accountant or finance specialist is the right person to confirm the calculation. Rate-only comparisons commonly mislead.
Run the maths
Run the calculator with the new-loan amount, term, and indicative rate to size the new monthly repayment. Comparing this against the existing repayment and switching-cost stack is the input to the refinance decision. The accountant is the right person to confirm the all-in cost-of-credit figure.

Methodology
The figures in this guide are indicative, drawn from observed NZ business-lending pricing across major banks (ANZ, ASB, BNZ, Westpac, Kiwibank), registered specialist banks (Heartland), and active alternative lenders (Prospa NZ, Bizcap, Avanti). Rate bands are illustrative ranges, not quotes. Switching cost components are referenced against publicly available fee disclosures and PPSR fee schedules from the Companies Office.
Break-cost methodology follows the NZ market practice of computing the lender's actual loss against current wholesale funding rates. The Reserve Bank of New Zealand publishes wholesale rate data; lenders' own product disclosure statements set out the exact break-cost formula in each contract. Specific calculations vary by lender and contract.
Tax treatment of refinancing costs (whether establishment fees, break costs, and legal fees are deductible against business income, capitalised, or amortised) is governed by Inland Revenue Department determinations and is subject to the accountant's confirmation on the specific business position. Most refinancing fees are deductible as business expenses where the borrowing relates wholly to business income, but the timing of deduction depends on the nature of the fee.
The figures and scenarios in this guide are indicative only and are not a quote, offer, or personalised financial advice. Final rates, fees, and approval decisions are made by the lender after assessment. Last reviewed 28 April 2026.

FAQ
Refinancing typically saves money when the rate gap between the existing loan and a like-for-like new loan, applied over the remaining term, exceeds the all-in switching cost (establishment fee, break cost, PPSR re-registration, and any legal or valuation fees). The maths is most often net positive at end of a fixed period (where break costs fall to zero), on floating-rate facilities, or where security has materially improved. Mid-fixed-period refinances during a falling-rate cycle are commonly net negative because break costs absorb the rate saving.
Break costs on NZ fixed-rate business loans are typically calculated on the lender's actual loss formula, comparing the rate at which the loan was written against the rate at which the lender can reinvest the prepayment in the wholesale market. When wholesale rates have fallen since origination, break costs are typically meaningful. When wholesale rates are flat or higher, break costs are commonly zero or near zero. The exact formula is set out in the loan contract; a written break-cost statement can be requested from the lender.
The all-in switching cost on a typical NZ business loan refinance (excluding break cost) commonly lands between $1,500 and $6,000, comprising establishment fee on the new loan (often 0.5% to 1.5% of the loan amount), PPSR registration and discharge (around $16 plus $8 per security), and where applicable, mortgage discharge and registration ($300 to $800), legal fees ($1,500 to $5,000), and valuation ($800 to $2,500). Break costs sit on top of this and are file-specific.
Refinancing during a fixed term is contractually permitted on most NZ business term loans, but break costs apply. The break cost compensates the lender for early termination of the fixed-rate funding behind the loan. Whether the refinance is economically worthwhile depends on the size of the break cost against the rate saving available on the new loan. End-of-fixed-period refinances are commonly the strongest candidates because break costs fall to zero at the natural maturity date.
A rate review with the existing lender avoids new establishment fees, PPSR re-registration, and break costs because the contract continues. The trade-off is rate movement, which is typically smaller than what a competitive refinance can achieve. Rate reviews on strong files at anniversary commonly return 0.25 to 0.75 percentage points of improvement; competitive refinances to a new lender can deliver more, at the cost of switching-stack fees. The choice depends on the size of the loan and the strength of the file.
Most refinancing costs (establishment fees, legal fees, break costs related to a business loan) are generally deductible against business income where the borrowing relates wholly to business activity, subject to the accountant's confirmation. Some fees are deductible in the year incurred, others may be capitalised and amortised over the loan term. Inland Revenue determinations govern the timing and treatment. The accountant is the right person to confirm the position on the specific business.
Unsecured refinances at alternative lenders commonly settle within 5 to 10 business days from application, subject to the lender's assessment. Major-bank secured refinances commonly settle within 3 to 6 weeks, with property-secured refinances at the longer end because of valuation and legal coordination. Multi-facility consolidations involving multiple discharges and re-registrations commonly add a further week. Timing depends on document completeness and the legal adviser's capacity.
A typical refinance application is commonly accompanied by 12 months of bank statements, the most recent set of financial statements (often 1 or 2 years), an aged debtors and creditors listing, a current personal-position statement from the directors or owners, the existing loan contract, a written break-cost statement from the existing lender, and where security is involved, valuation reports on the offered assets. Property-secured refinances additionally require LIM and title information.
A refinance application typically generates a credit-file enquiry on the business and on personally-guaranteeing directors. Multiple enquiries within a short window can affect the Centrix score, though business-credit-file impacts are generally less severe than personal-credit-file impacts. The closure of the existing facility and opening of the new facility appear on the file as expected. A specialist broker can sometimes coordinate comparisons with a single enquiry rather than multiple.
Refinancing when trading has weakened is harder, and rate movement is commonly unfavourable rather than favourable. New lenders price against the current credit story, and a weaker story typically returns a higher rate, not a lower one. Where weakened trading is the trigger, the conversation often shifts from a rate refinance to a workout or restructure with the existing lender, which is a different process. The lender's commercial team is the right contact for that conversation.
Alternative-lender short-term loans (typically 6 to 24 months) often carry factor-rate structures where the full contracted interest is payable regardless of payoff date. Mid-term refinancing of these facilities commonly does not save money on the existing loan, because the early-repayment fee replaces the saved interest. These facilities are commonly retired at natural contract end rather than refinanced. A consolidation refinance into a new bank loan that pays out the alt-lender facility is sometimes structured around the contract end date for this reason.
End of fixed period is commonly the strongest refinance window because break costs fall to zero at the natural maturity date, the lender is reviewing the file for renewal at the same time (so a competing offer is at its most relevant), and any improvement in trading or security position over the term can be priced into the new structure. Many NZ businesses align the refinance conversation with the 6 to 8 week window before fixed-term expiry for this reason.
A refinance creates a new loan with a fresh term selected at application. Where the new term is longer than the remaining term on the existing loan, monthly repayments fall but total interest paid over the full life can rise materially, even at a lower rate. Where the new term is the same or shorter than the remaining term, total interest typically falls in line with the rate improvement. The term decision is independent of the rate decision and is commonly the larger driver of total cost.
