Quick answer

What you need to know about working capital finance.

  • Short-term 6 to 24-month structures fund operating cash gaps, not long-term assets.
  • Four common structures short-term loan, line of credit, overdraft, invoice finance. Pick by scenario.
  • Indicative 12% to 25% p.a. unsecured. Secured working capital prices below; invoice finance prices per cycle, not annualised.
  • Test the maths first is the upside (margin, discount, contract value) larger than the cost of credit? If not, rethink.

What it is

Smoothing the gap between money out and money in.

Working capital is the money a business needs to run its day-to-day operations: paying suppliers, covering wages, holding stock, and bridging the gap between selling something and getting paid. When operating cash flow is uneven, working-capital finance fills the gap.

New Zealand businesses commonly use four structures for it: a short-term unsecured term loan, a revolving line of credit or overdraft, invoice finance, or a chattel-secured drawdown facility. The right structure depends on whether the cash gap is one-off or recurring, and how much certainty exists around the inbound side.

Common scenarios

When NZ businesses borrow for working capital.

Working-capital finance is rarely about a structural problem. The five scenarios below cover the bulk of NZ small-business working-capital lending volume in 2026. Each scenario maps to one or two structures that fit best.

01

Late customer payments

A B2B business waiting on 60 to 90-day invoices needs cash now to pay wages, suppliers, and rent. Invoice finance or a line of credit typically fits.

02

Seasonal pre-stock build

Retailers ordering pre-Christmas stock, hospo operators buying in for summer, garden centres preparing for spring. A short-term loan repaid out of the season fits.

03

Payroll smoothing

A growing services business hiring ahead of revenue catching up. Wages out today; client billings settling in 30 days. A line of credit or short bridge loan covers the gap.

04

GST or provisional tax

A bill landing at an awkward point in the cash-flow cycle. Tax pooling (Tax Traders, TMNZ) often beats a generic loan; otherwise a 6 to 12-month working-capital loan typically fits.

05

Supplier early-pay discount

A 5% early-payment discount on a $50,000 order beats a 6-week loan at most NZ working-capital rates. The maths is the trigger; running the numbers first is the standard test.

06

Contract win, working capital required

A new contract requires upfront wages, stock, or fit-out before milestones invoice. The contract value typically supports a short-term loan against the receivable.

Structures

Four structures that fit working capital in NZ.

The right structure depends on whether the cash gap is one-off or recurring, the size of the gap, and what (if any) security is on the table.

Short-term loan

Take it once, use it once, repay across 6 to 18 months. Suits a defined one-off cash gap.

  • Rate band: 14% to 22% unsecured
  • Suits: Tax bills, stock builds, contract starts

Line of credit

Pre-approved limit. Draw, repay, redraw. Interest only on the drawn balance.

  • Rate band: 12% to 20% on drawn balance
  • Suits: Recurring or unpredictable cash gaps

Business overdraft

Bank-account-attached buffer. The traditional NZ bank-led structure.

  • Rate band: 10% to 16% (often property-secured)
  • Suits: Mature businesses, ongoing buffer

Invoice finance

Lender advances 70-90% of unpaid B2B invoices. Cash today; balance settles when customer pays.

  • Cost: 1.5% to 3% per invoice cycle
  • Suits: B2B with creditworthy customers

Decision matrix

Which structure fits which scenario.

No single structure suits every working-capital scenario. The matrix below is a starting point; the accountant or broker conversation refines it.

FeatureShort-term loanLine of creditOverdraftInvoice finance
One-off cash gap, defined sizeBest fitWorksOverkill (ongoing fee)No (need invoices)

Seasonal business low seasonMarginal (term match)Best fitWorksNo (no invoices in low)
No or very thin securityBest fit (specialist lenders)Works (specialists)No (security required)Works (invoices act as security)

"Best fit" means the structure is widely chosen for this scenario; "works" means viable but not the optimal pick; "marginal" means usable but better alternatives commonly exist.

How it works

A typical NZ working-capital application.

Working-capital applications, particularly unsecured ones, run faster than asset-secured loans because there is no specific asset to value. Online applications for established businesses commonly fund within a business day on amounts under $150,000.

  1. 01

    Day 1

    Define the cash gap

    Lenders ask "how much, for what, repaid from what". A clear answer (e.g. "$25K for pre-Christmas stock build, repaid out of December and January sales") reads stronger than a vague "$25K for working capital". Specificity tightens the rate band and shortens the assessment.

    Documents commonly required

    • One-line loan purpose
    • Repayment source narrative
  2. 02

    Day 1

    Submit the application

    Standard documents include business owner ID, NZBN, last 6 months of business bank statements, and the loan purpose. Larger amounts (above $150,000) commonly add a P&L statement and an aged debtors report. Self-employed and sole-trader applicants commonly include the last 12 months bank statements and an accountant's letter.

    Documents commonly required

    • Business owner ID
    • NZBN registration
    • Last 6 months business bank statements
    • Loan purpose
    • Aged debtors report (if amount > $150K)
    • P&L (if amount > $150K)
  3. 03

    Day 1 to 3

    Credit assessment and offer

    The lender runs a credit check on the business and any directors providing personal guarantees, assesses affordability against monthly turnover (commonly looking for repayments at less than 25% of monthly net cash flow), and offers a rate, term, and weekly repayment. The offer typically holds for 14 to 30 days.

  4. 04

    Day 1 to 5

    Settle and draw

    On a short-term loan, funds typically draw to the business bank account on signing. On a line of credit or overdraft, the facility opens and funds draw on demand. Interest accrues from the draw date, not the application date, on revolving structures.

Heartland Open for Business and Prospa's Small Business Loan are both designed for same-day decisions on amounts under $150,000 with established trading history.

Worked scenarios

Three NZ working-capital scenarios.

How the structure choice and cost play out across three different NZ borrower profiles.

Retail

Newmarket retailer pre-Christmas stock

A homewares retailer placing a pre-Christmas order. Suppliers want payment on order; the stock typically sells through November and December. Cash gap: 12 to 14 weeks.

Structure: $25,000 short-term loan at indicative 18% p.a. across 12 months. Total interest ~$2,500. Stock generates ~$50,000 revenue at 50% margin = $25,000 gross margin. The interest cost is 10% of margin; well covered.

Professional services

Wellington consulting firm payroll smoothing

A growing consultancy with $35K/month payroll, billing clients on 30-day terms. Bills out Monday, paid 35 days later. Need a $50,000 line of credit to bridge each cycle.

Structure: $50,000 line of credit at indicative 15% p.a. on the drawn balance. Average drawn balance ~$30,000. Annual interest cost ~$4,500. Suits the recurring nature of the gap perfectly.

Manufacturing

Auckland supplier invoice finance

A specialty food manufacturer supplying NZ supermarket chains. Invoices on 60-day terms; a single $80,000 invoice creates a working-capital gap.

Structure: invoice finance facility advancing 85% of invoice value ($68,000 immediately) at 2.5% per cycle (~$2,000 fee for the 60-day cycle). Balance ($12,000 less fee) settles when customer pays.

Common pitfalls

Where working-capital borrowing goes wrong.

Working capital finance fits a defined operational cash gap. The pitfalls below are the patterns where a working-capital loan is a band-aid on a deeper problem.

01

Borrowing for a structural margin issue

If working capital is recurring even in good months, the underlying issue is margin, pricing, or cost structure, not cash flow. A loan masks the problem; the business eventually cannot service the debt.

02

Stretching the term too long

A 5-year loan to fund 3 months of working capital means the business is still paying interest 4 years after the operational gap closed. Working-capital terms commonly cap at 24 months for good reason.

03

Missing the alternative (tax pooling, supplier credit)

For IRD bills, tax pooling commonly beats a working-capital loan. For supplier-driven gaps, negotiating extended terms with the supplier is sometimes free. Test the alternatives first.

04

Borrowing without testing the maths

If the upside (margin, discount, contract value) is smaller than the cost of credit, the loan loses money. The supplier-discount scenario only works if the discount beats the loan cost. Run the numbers first.

05

Stacking multiple working-capital loans

Taking a second working-capital loan while the first is still outstanding compounds risk. NZ lenders increasingly check for stacked debt; visible existing facilities tighten or block new applications.

06

Personal guarantee blind spot

Most unsecured working-capital loans require a director PG. The PG is recoverable against personal assets if the business fails. Treat the borrowed amount as personally guaranteed, not just business-owed.

Lenders to know

NZ lenders that fund working capital well.

Working-capital lending in NZ is dominated by alternative lenders and specialist non-banks for unsecured products, with the major banks competing on secured overdrafts and lines of credit.

FAQ

Working capital, NZ small-business questions answered

What is a working capital loan?

A working capital loan is short-term finance used to cover day-to-day operating costs rather than to buy a long-term asset. Common uses include paying staff wages, covering supplier invoices, buying stock ahead of a busy season, and smoothing GST or provisional tax payments. Terms typically run 6 to 24 months because the gap being funded is operational rather than a long-term investment.

When does a NZ small business actually need working capital finance?

Common scenarios observed in the NZ market include a seasonal business heading into a quiet period, a contract-based business waiting on a delayed customer payment, a retail or hospitality business buying stock ahead of summer or Christmas, and a growing business hiring or expanding faster than its inbound cash supports. The trigger is usually a known short-term gap rather than a structural problem.

Should I use a line of credit or a term loan for working capital?

A line of credit suits recurring or unpredictable cash gaps because interest is charged only on the drawn balance and funds can be drawn and redrawn. A term loan suits a one-off, sized funding need where the loan is taken once, used, and amortised. Many NZ small businesses run both: a small line of credit for ongoing volatility, plus the occasional term loan when a defined funding need lands.

What's the typical interest rate on working capital finance in NZ?

Indicative rates on unsecured working capital finance commonly sit in the 12% to 25% per annum band, depending on the trading history of the business, the monthly turnover, the loan term, and the lender. Secured working capital facilities (asset-backed or property-backed) typically price below the unsecured band. Invoice finance prices differently because it is structured as a percentage of invoice value rather than an annualised rate.

Is invoice finance a kind of working capital loan?

Yes, invoice finance is one of the established working capital structures in New Zealand. The lender advances a percentage of unpaid customer invoices (commonly 70% to 90%), the business gets the cash today, and the balance settles when the customer pays. Specialist providers like FundTap, Lock Finance, and Scottish Pacific NZ run this structure. It suits B2B businesses with creditworthy customers and long invoice-to-payment cycles.

How long does a working capital loan typically run for?

Common terms in the NZ market run 6 to 24 months. Anything longer than 24 months on operating cash flow is typically a sign the underlying problem is structural (a margin issue, a pricing issue, a customer-concentration issue) rather than a working-capital one. Lenders commonly look at the loan purpose carefully where the requested term is long.

Can a sole trader get a working capital loan?

Yes, sole traders are eligible for working capital finance from many NZ lenders, particularly the alternative-lender segment. The application typically references both the business trading history and the personal financial position, because the sole trader and the business are the same legal person. A clean credit file, NZBN, and 6 to 12 months of trading history are the common minimum requirements. Sole-trader applications can occasionally trigger CCCFA where the borrowing is wholly or predominantly for personal use.

Is the interest on a working capital loan tax-deductible?

Interest on a loan used wholly for business purposes is generally deductible against business income in New Zealand, subject to the accountant's confirmation. Working capital finance is typically clearly business-purpose, so the deductibility position is usually straightforward. Where the loan is mixed-use (partly personal), the interest deduction is apportioned. The accountant is the right person to confirm the specific position.

How is the working capital loan repaid?

Short-term term loans are repaid on a fixed schedule (commonly weekly), with the operating cash flow covering the repayments as the business catches up on the gap. Lines of credit and overdrafts are repaid as cash inflows allow, with interest charged only on the drawn balance. Invoice finance self-liquidates: the customer payment clears the advance.

Can I refinance an existing working capital loan to a better rate?

Often yes, particularly after 12 to 24 months of clean repayments where the trading history has improved. The most common refinance trigger is a credit profile improvement that opens access to mainstream-bank pricing rather than alternative-lender pricing. Early repayment fees on the existing loan are the main consideration; some products allow unlimited extra repayments at no cost, others charge a break fee on early settlement.

What are common pitfalls with working capital borrowing?

The biggest pitfall is borrowing for what is actually a structural problem (margin, pricing, customer concentration) rather than a temporary cash gap. Other common pitfalls: stretching the term beyond the cash gap, missing cheaper alternatives like tax pooling for IRD bills, not testing whether the upside beats the cost of credit, and stacking multiple working-capital loans across different lenders.

What documents do I need for a working capital application?

Standard documents are business owner ID, NZBN registration, the last 6 months of business bank statements, and a brief on the loan purpose and repayment source. Larger applications above $150,000 commonly add a P&L statement, an aged debtors report (showing who owes the business and how old the debts are), and a 12-month cash-flow forecast. Self-employed applicants often add an accountant's letter.

Indicative content only. Not personalised financial advice.

A business loan is a commitment that runs for months or years, and repayments come out of the same operating cash flow as everything else. Before committing, it is worth modelling the weekly and monthly cost against the business's working-capital position, which is what this site is built to help with. Borrowing at a level that stays comfortable through a quiet quarter, not just a strong one, is widely regarded as the safer frame.
