TL;DR: Finance plant the way you finance a ute — match the loan term to the gear's real working life, secure it against the asset, and factor in the GST you get back if you're registered. Niche or low-resale gear often needs a bigger deposit because the lender has less to fall back on. A chattel mortgage is usually the cleanest structure for a business that owns its plant.
---
A digger doesn't earn anything sitting on a dealer's yard. It earns when it's on your site, moving dirt and paying for itself. The whole point of plant and equipment finance is to get the gear working for you now, then let the work it does cover the repayments.
This is the pillar guide to financing the big stuff: diggers, excavators, scaffolding, generators, compressors, trailers and the specialist tools that cost real money. Most of the rules are the same as financing a ute, but plant has a few quirks worth knowing before you sign.
## What counts as plant and equipment
When a lender or your accountant says "plant and equipment", they roughly mean any business asset that isn't a building or a road-registered vehicle. For a trade business that usually means:
- **Earthmoving and access gear** — excavators, diggers, skid steers, telehandlers, scissor lifts, EWPs (elevated work platforms).
- **Scaffolding and edge protection** — a full kit is a serious capital item, often $30k–$100k-plus.
- **Power and site gear** — generators, compressors, welders, lighting towers, pumps.
- **Trailers and attachments** — plant trailers, tippers, augers, buckets, breakers.
- **Specialist tools** — concrete saws, laser levels, line markers, the kit specific to your trade.
If it earns over years rather than being a cost you burn through this month, it belongs in the [asset finance](/glossary/secured-vs-unsecured-finance) box, not on the [business overdraft](/glossary/business-overdraft) — a split we cover in the [asset finance vs bank overdraft guide](/guides/asset-finance-vs-bank-overdraft).
## Why you finance plant instead of paying cash
Even when you've got the cash, tying it all up in one excavator is rarely the smart move. Finance spreads the cost across the years the gear is earning, so the asset pays for itself out of revenue rather than draining the bank account you need for wages, materials and the quiet fortnight. The classic mistake is funding a $90k digger out of working capital, then scrambling on the overdraft three months later when a big invoice runs late. Keep the cash for cashflow; finance the asset against itself.
Match the loan term to the working life of the gear, and pay for it out of the money it earns — not out of the cash you need to run the business day to day.
## How plant finance is structured
Most plant in a trade business is bought on a [chattel mortgage](/glossary/chattel-mortgage). Your business owns the gear from day one, the lender registers a [security interest](/glossary/security-interest-ppsr) over it on the PPSR, and you make fixed repayments over the term. Because the loan is secured against a real, resaleable asset, the rate is usually sharper than unsecured business lending.
Because plant is genuine business-purpose finance, it sits largely outside the consumer CCCFA regime that governs personal lending — which is part of why business asset finance can move faster than a consumer loan. You'll usually sign a [business purpose declaration](/glossary/business-purpose-declaration) confirming the gear is for your business. More on that in our [does the CCCFA apply to my business loan](/blog/does-the-cccfa-apply-to-my-business-loan) explainer.
The other common structures:
- **[Hire purchase](/glossary/hire-purchase)** — similar in feel; you take ownership at the end. Often used by sole traders or where the accountant prefers it.
- **[Finance lease](/glossary/finance-lease)** — you use the gear and there's a [residual value](/glossary/residual-value) at the end you can pay out to own it.
- **[Operating lease](/glossary/operating-lease)** — closer to a long-term rental; the lender keeps the asset risk and you hand it back. Good for fast-changing or short-need gear.
Which one fits depends on whether you want to own the gear long-term, how long you'll keep it, and how your accountant wants it on the books. Our [buying vs leasing guide](/guides/buying-vs-leasing-equipment-for-tradies) walks through that decision properly. We're a broker, not a lender — we work across a panel of lenders and place each application where the structure and the gear actually fit, rather than squeezing you into one lender's product.
## Matching the term to the gear's working life
This is the single most important number to get right. The term should roughly track how long the asset will genuinely earn for you and hold value.
- **A scaffolding kit or a quality digger** might earn hard for 7–10 years. A longer term (5–7 years) can make sense because the asset keeps working long after the loan's gone.
- **A generator or compressor** that gets thrashed on site might have a shorter real life — don't stretch the loan past the point it's still your best earner.
- **Specialist or fast-wearing tools** should be on shorter terms again. Paying for a concrete saw in 2031 that died in 2028 is how good businesses end up underwater on gear.
Stretch the term too far and the monthly repayment drops, which feels nice — but you risk owing more than the gear is worth, and paying for something that's stopped pulling its weight. Too short and the repayment can choke your cashflow. The sweet spot is a repayment your job rates comfortably absorb, over a term that ends before the gear does. The [work vehicle finance guide](/guides/work-vehicle-finance-guide) applies the same logic to utes and vans.
If the loan term is longer than the gear's realistic working life, you'll be making payments on something that's already in the scrap pile or sold off cheap. Always sense-check the term against how long this specific piece of plant will really earn.
## New vs used plant
Plenty of tradies build a business on good used gear, and lenders will finance it — but there are real differences.
| | New plant | Used plant |
|---|---|---|
| Price | Higher up front | Lower entry cost |
| Finance term available | Longer terms common | Often capped (lenders look at age + hours) |
| Deposit | Often lower | Often higher, especially older gear |
| Reliability | Warranty, fewer surprises | Depends on hours and history |
| Resale | Holds value if it's a known brand | Already taken the early depreciation hit |
Lenders care a lot about **age and hours** on used plant. An excavator with low hours from a reputable dealer is easy to finance; a high-hour, end-of-life machine from a private sale is harder, may need a bigger deposit, and might only get a short term. Get an independent inspection on serious used gear before you commit.
## Residual values, deposit and the resale question
Lenders lend against what the gear is worth and what they could recover if things went wrong, so **resale matters a lot** for plant.
- **Mainstream, in-demand gear** (well-known excavator brands, standard scaffolding, common generators) has a deep second-hand market. Lower risk for the lender usually means a smaller [deposit](/glossary/deposit) and better terms.
- **Niche, specialist or low-resale gear** — a one-off custom rig, a trade-specific machine with a thin used market, or something that dates fast — is harder to value and offload. Expect to put down **more deposit** to cover the gap between the price and what the gear would fetch in a hurry.
A [residual value](/glossary/residual-value) or balloon payment can lower your regular repayments by parking a lump sum at the end — handy for cashflow, but you'll need to pay it out, refinance it, or sell the gear to clear it. Use it on assets that genuinely hold value; don't stack a big residual on gear that'll be worth little when it's due.
The deposit closes the gap between what you paid and what the lender could realistically recover. On mainstream plant that gap is small. On niche gear with a thin used market, the gap is bigger — so the lender asks you to fund more of it up front. It's not personal; it's the resale maths.
## Security and the PPSR
When you finance plant, the lender registers a [security interest](/glossary/security-interest-ppsr) against it on the Personal Property Securities Register (PPSR). That's the public record showing the gear has money owing on it. It protects the lender, and it protects you from accidentally buying gear that someone else still has a loan over.
Two practical things:
1. **Check the PPSR before buying used plant.** If you buy a digger that already has a security interest registered against it and the seller doesn't clear their loan, you could lose the machine. A quick PPSR search before money changes hands is cheap insurance.
2. **Your own gear will show a registration** until the loan's paid off. That's normal. Once you clear the loan, make sure the security interest is discharged.
## GST and depreciation on plant
If you're [GST-registered](/glossary/gst-registration) and the gear is for business use, you generally claim the [GST back](/glossary/gst-on-asset-finance) on the purchase price — and on most asset finance that GST comes back up front, behaving a bit like an extra deposit. The rule is the 3/23 calculation on the GST-inclusive price: price ÷ 23 × 3.
Separately, your business [depreciates](/glossary/depreciation) the gear against business income over its life. Plant has its own IR depreciation rates by asset class — different from vehicles — so confirm the right rate and method with your accountant or the IR rate finder (rates change; check the current one with IRD).
Two things tradies regularly get wrong:
- **The loan and the depreciation are separate.** You depreciate the *asset's value*; you separately deduct only the *interest portion* of your repayments. The principal you pay back isn't a deduction.
- **Depreciation recovery on sale.** If you sell or trade the gear for more than its written-down (tax) value, the difference is usually clawed back as taxable income in the year you sell. Good gear that holds value can trigger a tax bill at sale time — plan for it. Our [chattel mortgage depreciation guide](/guides/chattel-mortgage-depreciation-work-ute) walks through exactly how that plays out.
Always confirm the tax treatment with your accountant or IRD — this is general guidance, not advice on your specific books.
## A worked example: a $90k digger
A drainage contractor (limited company, GST-registered) buys a **$90,000 GST-inclusive** excavator from a reputable dealer — known brand, low hours. They finance it on a [chattel mortgage](/glossary/chattel-mortgage) over 5 years.
**Step 1 — the GST back:**
- GST component: $90,000 ÷ 23 × 3 = **$11,739** (illustrative), claimed back on the next GST return.
- That GST refund effectively funds a chunk of their deposit and eases the early cashflow.
**Step 2 — the deposit:**
Because this is mainstream, easily-resold gear, the lender is comfortable with a modest deposit, which the contractor covers with cash plus the GST refund. Buying a **niche, custom-built rig** with a thin resale market instead, they'd likely have been asked for a **larger deposit** to cover the resale gap.
**Step 3 — match the term to the work:**
A quality excavator earns well beyond 5 years, so a 5-year term is sensible — the digger keeps working and holding value after the loan's cleared. They could go longer to drop the monthly payment, but they'd rather own it free and clear while it's still a strong earner.
**Step 4 — the deductions, separately:**
- The business **depreciates** the GST-exclusive cost (~$78,261) at the IR rate for that plant class.
- The business **deducts the interest** portion of each repayment.
- The **principal** portion isn't deductible — it's just repaying borrowed money.
**Step 5 — plan for the sale:**
If they later sell or trade the digger for more than its written-down tax value, the difference is **depreciation recovery** and is taxable. Not a penalty — just the system reconciling — but worth provisioning for so the trade-in year doesn't sting.
The headline: the digger is working from day one, the GST is back in the bank quickly, the repayment is built into their job rates, and the structure does the heavy lifting — which matters far more than chasing the last fraction off the rate. A cheap-looking rate with the wrong term or a fat residual can quietly cost you more; we cover that trap in the [real cost of a cheap finance rate](/blog/the-real-cost-of-a-cheap-finance-rate).
## Quick decision checklist
1. **Is it gear that earns over years?** → Asset finance (usually a chattel mortgage), not the overdraft.
2. **How long will this specific machine really earn?** → Set the term to end before the gear does.
3. **New or used?** → Used is fine; expect lenders to weigh age and hours, and possibly want more deposit.
4. **Mainstream or niche gear?** → Niche/low-resale usually means a bigger deposit.
5. **Buying used?** → Search the PPSR first, get it inspected.
6. **GST-registered?** → Factor the GST claim-back into your deposit conversation; confirm depreciation with your accountant.
## Where to from here
Plant finance isn't complicated once the structure's right: match the term to the work, secure it against the asset, put in the deposit the resale maths calls for, and keep your accountant across the GST and depreciation. The rest is choosing the right lender for the gear — which is exactly what a broker does.
