Buying your first home is a huge milestone — and buying at auction can feel like stepping into a completely different world.

For many first-home buyers in New Zealand, auctions are exciting, fast-moving, and sometimes a little intimidating. The pace is quick, emotions can run high, and if you’re the winning bidder, you need to be ready to move immediately. That’s why it’s so important to understand exactly what you’re getting into before auction day arrives.

If you’re thinking about buying your first home at auction, here are a few key things to know.

What makes auctions different?

Unlike a private sale, buying at auction is usually unconditional. That means once the hammer falls, you generally can’t make the purchase subject to finance, a builder’s report, or any other conditions.

If your bid wins, the property is yours.

That speed can work in your favour — but only if you’ve done all your preparation beforehand. For first-home buyers especially, being prepared is everything.

The deposit you need on the day

One of the biggest surprises for many first-home buyers is how much deposit is required immediately after an auction.

In most cases, if you’re the successful bidder, you’ll need to pay a 10% deposit on the spot. These funds usually need to be cleared and ready to transfer straight away.

So, if you buy a property for $750,000, you may need $75,000 available that same day — not next week, and not once KiwiSaver is released.

This is where many buyers get caught out. You might technically have enough for a deposit overall, or know you have KiwiSaver available, but that doesn’t mean you have immediate access to the cash needed on auction day.

Why KiwiSaver usually won’t cover the auction deposit

KiwiSaver can absolutely help you buy your first home — and for many buyers, it’s a crucial part of getting into the market.

But there’s an important catch when it comes to auctions: KiwiSaver withdrawals take time to process.

That means the money typically isn’t available instantly when the auction ends. If you’re planning to bid at auction, you’ll usually need another source of funds ready for the deposit on the day.

In simple terms, KiwiSaver may help you purchase the home overall, but it generally won’t help you pay the auction deposit unless you already have cash available.

What you should have sorted before auction day

If you’re serious about bidding at auction, it’s important to have everything lined up beforehand, including:

• A clear understanding of your borrowing power

• Pre-approval from your lender

• A solicitor ready to review the auction documents

• Your building report, LIM, and due diligence completed

• Deposit funds available immediately

• A budget for legal fees, moving costs, and settlement expenses

The buyers who tend to do best at auction aren’t always the ones who bid the highest — they’re the ones who prepared properly well before the auction began.

The risks to keep in mind

Auctions can be a great way to buy property, but they do come with extra pressure compared to a standard private sale.

You need to feel comfortable with the fact that:

• There’s very little time to rethink your decision once bidding starts

• Competition can push buyers beyond their comfort zone

• You may be committed without finance or inspection conditions

• You need complete confidence in both the property and your budget

For first-home buyers, that can feel like a lot to manage all at once. And if your deposit is already tight, or you’re relying on funds that aren’t immediately accessible, the pressure can build quickly.

When auctions can still be a good option

That said, auctions aren’t automatically the wrong choice.

They can work really well if you:

• Already have your deposit ready

• Know exactly what you can borrow

• Have completed all your due diligence

• Feel comfortable buying unconditionally

• Prefer a clear and fast process

If that sounds like you, auction day could be a great fit. If not, a private sale may give you more flexibility and less stress.

The advice I give first-home buyers

After more than 26 years as a mortgage broker, I’ve learned that helping people buy a home is about far more than just getting a loan approved. It’s about helping you make a smart decision that fits your financial situation and your long-term goals.

When first-home buyers ask me about auctions, I usually start with a few simple questions:

• Do you have the deposit ready right now?

• Can you comfortably cover the 10% required on the day?

• Have you factored in KiwiSaver processing times?

• Are you comfortable buying without conditions?

If the answer to any of those questions is no, it’s worth slowing down and exploring your options before putting your hand up at auction.

Final thoughts

Buying your first home is exciting, and auctions can absolutely be part of that journey — but preparation is key.

Make sure you understand the deposit requirements, know how KiwiSaver fits into the process, and have your finance organised well before auction day. If you do, you’ll walk in feeling far more confident and far less stressed.

The best first-home purchase isn’t necessarily the fastest one — it’s the one that’s right for you, your budget, and your future
