Quick answer
Investment Boost lets New Zealand businesses deduct 20% of the cost of a new depreciable asset in the year it is first available for use, as long as that was on or after 22 May 2025. Second-hand assets sourced in New Zealand don't qualify. If a machine or vehicle dies and you must replace it fast, the order, the delivery and the finance should be lined up so the asset is ready for use before balance date.
Key points
- The deduction is 20% of cost, claimed in the year the asset is first available for use.
- New, or new to New Zealand, qualifies. Second-hand assets bought in New Zealand don't.
- Availability for use, not the invoice date, is what counts. Delivery and set-up matter.
- It's a timing benefit: the cash arrives through lower tax, not on the purchase day, so the purchase itself still needs funding.
The press brake cracks, the ute’s gearbox goes, or the commercial oven won’t light the week before your busiest trading. You need a replacement now. In the rush, one date quietly decides whether you also pick up a 20% first-year tax deduction: the day the new asset is first available for use.
This guide is about that sequence. It covers what Investment Boost actually rewards, how a fast purchase can miss it, and how to line up the money so the deadline and the paperwork both hold.
What does Investment Boost give a business that replaces equipment?
Investment Boost is a deduction of 20% of the cost of a new depreciable asset, claimed in the year the asset is first available for use. IRD applies it to assets first available for use on or after 22 May 2025, with no cap on how much you can invest. You then depreciate the asset as usual on the remaining cost.
Two things to hold onto:
- It is a timing benefit. It brings deductions forward, so tax falls sooner. It doesn’t put cash in your account on the day you buy.
- It only helps if the business has taxable income to deduct it against, so a loss-making year changes the picture. Your accountant can say what it’s worth to you.
For example, a company that buys a $100,000 machine could claim an extra $20,000 deduction in year one. At the 28% company rate, that is $5,600 less tax in that year. Useful, but nowhere near the $100,000 you need to find first.
Which assets qualify, and which don’t?
IRD’s guidance sets out the test. An asset qualifies if it is depreciable and either brand new or new to New Zealand, which can include something previously used overseas.
| Likely to qualify | Excluded |
|---|---|
| New machinery, tools and equipment | Used gear bought from a New Zealand seller |
| Assets imported and new to New Zealand (even if used overseas) | Residential rentals |
| New commercial or industrial buildings | Most intangibles with a fixed life (patents) |
| Upgrades to depreciable assets | Land |
The asset also can’t have been put to use here before, apart from sitting in a dealer’s stock. A one-off demonstration while it was for sale doesn’t count against it.
Vehicles sit in the same framework, since work vehicles are depreciable property, but IRD’s page doesn’t walk through vehicle examples. Ask your accountant to confirm how it applies to your particular vehicle, especially if it is an imported used one or has private use.
When does an asset count as “available for use”?
This is where fast purchases go wrong. Under IRD’s guidance, an asset is available for use once you could lawfully and practically put it to work, even if you haven’t started. For improvements, such as a fit-out, the asset qualifies only once complete, or complete to an identifiable stage that increases its capital value.
That means the invoice date, the deposit date and the payment date are not the test. What matters is delivery, installation, any compliance sign-off and registration.
Picture a Timaru joinery firm with a 31 March balance date. It pays a deposit on a CNC router in mid-March, but the machine is delivered and wired in on 8 April. The deposit might feel like “buying it in March”, yet the router wasn’t ready for use until the next tax year, so the 20% moves a year later. The same machine on site and commissioned by 28 March would have counted.
If you have a standard 31 March balance date, the last few weeks before it are when this timing risk is greatest. If your balance date is different, work back from yours.
What should you do first when something critical breaks?
A tight sequence beats scrambling. Here’s the order that tends to work:
- Get a written quote and delivery date. Ask the supplier for the date it will be installed and operating, not just shipped. Anything slipping past balance date is worth knowing about now.
- Check whether it is new or new to New Zealand. A second-hand machine from a local dealer won’t qualify, so the deduction shouldn’t be what justifies the choice.
- Check for existing security on used assets. If you’re buying second-hand, search the Personal Property Securities Register for the serial number or VIN. A finance company’s interest that’s still registered can follow the asset to you.
- Keep the evidence. Hold on to the invoice, any import paperwork and proof of the date the asset was ready to use, in case IRD asks.
- Line up the funding in parallel. Don’t wait for the supplier to chase a deposit before you approach a funder; see if you qualify while the quote is still fresh.
Do you need the funding before or after the quote?
Both, ideally at the same time. Funders look at the same things whatever the asset: how long you’ve traded, what goes through your business account, and the amount against the purchase price. The quote is useful, but it isn’t a blocker for a first conversation.
What helps a quick answer:
- the supplier quote, including GST and the delivery date
- recent business bank statements
- confirmation of who owns the business (company, trust or sole trader) and who signs
- a view of whether the purchase replaces something broken or adds capacity
For equipment and vehicle finance, the asset can sometimes be the security. For smaller amounts, unsecured business loans are sized on turnover, and same-day funding is possible for smaller unsecured amounts. If the amount is larger and you have property equity, a second mortgage is another route, with $20k to $250k possible same day (property-secured) once valuation and signing are done.
Not sure which route fits? The funding speed finder gives you a realistic idea of timing before you commit to a supplier’s delivery date.
Don’t let the deduction drive the decision
A 20% deduction is a nice reason to buy new, but it can be a poor reason to buy at all. A few traps:
- Buying to hit balance date. A machine you don’t need still costs the full price. The deduction recovers a slice of tax, not the cost.
- Ignoring the cash gap. The tax benefit arrives through lower provisional or terminal tax months later. If the purchase also coincides with a GST return or a provisional tax date, the cash pinch is real. The guide on planning around GST and provisional tax dates covers how to space those out.
- Forgetting that depreciation continues. If you claim Investment Boost on a depreciable asset, you must depreciate it. That’s part of the normal tax treatment, and your accountant will handle it, but it’s worth knowing the 20% isn’t the whole story.
- Mistaking items under $1,000. Low-value assets (GST-exclusive cost of $1,000 or less for a GST-registered business) can be written off immediately under a separate rule. IRD’s draft guidance is clear that you can’t split one asset into pieces to get under it.
How do lenders see an urgent replacement purchase?
Lenders care less about the tax treatment and more about whether the new asset earns money. A replacement for something that was producing revenue is an easy story: the business was earning with the old machine, and it will again. Say that plainly. If the machine is also new capacity, show the work it will win.
It also helps to be upfront about what you’re asking for and by when. Our guide to what NZ lenders check before fast funding lists what a funder will look at, so you can have it ready before you ask.
Where this leaves you
If a key asset has just died, you have three jobs and they can run together: confirm the delivery and set-up date against balance date, confirm the asset really is new or new to New Zealand, and get the money organised so the supplier isn’t waiting on you. Do those, and the Investment Boost deduction is a bonus on a purchase you were making anyway.

Frequently asked questions
Is there a limit on how much I can claim under Investment Boost?
IRD sets no cap on how much you can invest. The deduction is 20% of the cost of each qualifying asset, and you must then depreciate the asset as normal.
Can I claim it on a used machine I buy in New Zealand?
No. Second-hand assets sourced locally are excluded. An asset that is new to New Zealand can still qualify after overseas use, so an imported used machine may be eligible. Check with your accountant before relying on that.
What is the difference between the invoice date and the available-for-use date?
Available for use means you could lawfully and practically use it, whether or not you have started. A machine paid for in March but still on a ship in April is unlikely to count for a 31 March balance date.
Does Investment Boost replace the $1,000 low-value asset rule?
No. Items costing $1,000 or less (GST-exclusive for GST-registered businesses) can still be written off immediately. IRD's draft guidance says the asset must be a genuinely separate item, and an Investment Boost deduction that takes the value under $1,000 doesn't make it a low-value asset.
Do I get the 20% back as cash?
Not directly. It reduces your taxable income for the year, so the saving shows up as lower tax, such as lower provisional tax or terminal tax. You still need the money for the purchase itself.
Can finance be arranged quickly for equipment?
Same-day funding is possible for smaller unsecured amounts, and larger amounts can be arranged against property. Timing depends on how complete the file is, so having the quote and your bank statements ready helps.
