What Type of Gold Bar Should I Buy in 2026? (Best Sizes, Brands & Bars Explained)

With gold prices near record highs in 2026, choosing the right type of gold bar has become more important than ever.

In this guide, you’ll learn the pros and cons of different gold bar sizes, the difference between cast and minted bars, when gold bars may make more sense than gold coins, and which types of bullion are often best suited for beginners versus larger investors.

Whether you’re buying your first piece of physical gold or expanding an existing bullion portfolio, this guide will help you understand what to look for before you buy.

What Type of Gold Bar Is Best for Most Investors?

For many New Zealand investors, 1oz cast gold bars from recognised local or international refiners often provide the best balance between affordability, low premiums, storage convenience, and long-term liquidity.

While minted gold bars may have a more polished appearance, cast bars are usually cheaper per ounce and are popular with investors focused primarily on maximising the amount of physical gold they own.

Smaller bars can help beginners accumulate gradually, while larger bars may suit higher net worth investors seeking lower premiums.

At Gold Survival Guide, many first-time buyers are surprised to learn that the “best” gold bar is not always the most expensive or visually polished option. Many experienced bullion investors instead prioritise lower premiums and maximum gold weight over collectability or presentation.

Here’s How to Choose What Type of Gold Bar to Buy

So you’ve considered the many reasons why you should buy gold and have made a decision to buy. You’ve also determined what percentage of precious metals you should own.

Now the question is what type of gold to buy? First up, you’ll most likely want to consider whether to buy gold bars or buy gold coins.

Why Buy Gold Bars?

The main reason to buy gold bars is because they are cheaper than gold coins. Gold coins require more “work” to produce them. They have the added work of designing both a front and back (or obverse and reverse) of the coin. But also the minting and machining process for a coin is far more involved than for a bar.

For more detail on the coins vs bars debate see: NZ Gold Coins or NZ Gold Bars: Which Should I Buy?

Therefore if your primary concern is simply to get the most gold for your money, then gold bars are probably the way to go.

What Size Gold Bar Should I Buy?

The next question to answer is what size gold bar to buy? Gold bars come in a plethora of sizes, from 1 gram to 400 ounces.

The general rule of thumb is, the bigger the bar the lower the premium over spot price per ounce. i.e. a bigger bar is a cheaper bar.

Why is that?

Well, it’s comparable to how a coin requires more “work” to produce than a bar. In much the same way, a larger bar requires about the same amount of work to pour or cast as a smaller bar.

So the net cost of fabricating the bars is quite similar. But a larger bar obviously has much more gold in it.

Therefore the overall cost per ounce of a much larger bar (such as a 1 kilogram bar) is lower than say a 1 ounce gold bar.

However like many things in life cheaper is not always the best option. More on that below…

Pros and Cons of Different Bar Sizes

400 ounce gold bars and 1kg gold bars offer the best value. That is you’ll get more ounces of gold for the same amount of money. That is why the likes of large institutional investors, central banks and exchange traded funds deal in 400 ounce bars. Exchanges in China more commonly deal in the kilo bar.

But there are disadvantages to buying larger bars. These include:

• Divisibility – a 1 kilogram gold bar cannot be sliced up into smaller parcels and sold when the need arises.
• Counterfeiting – Although counterfeiting of gold is not common, larger bars are a more likely target for counterfeiters. Why? Because there is a less chance of counterfeiting occurring in smaller 1 ounce bars, as it is not worth the time and effort. (The other main way to avoid counterfeits is to deal with a long standing gold dealer who sources direct from precious metals refiners and mints).
• Ease of resale – There are more potential buyers of smaller bars. Not many people can afford a 400oz gold bar, so when the time comes to sell you will have a smaller pool of interested buyers.

1kg Gold Bar Advantage: 1kg Bars Can be Borrowed Against

While we view gold as financial insurance with no counter-party risk, there are times when some people would like to be able to borrow against their gold.

Say you wanted to purchase a property, but didn’t want to sell the gold you had in order to do this. You may therefore choose to borrow against your gold.

As the only New Zealand brokers for the Singapore Precious Metals Exchange (SGPMX), we have an option available to borrow against gold stored in Singapore.

This borrowing is only available against 1kg gold bars. The minimum is 3 kilos of gold. Go here for more information about storage at SGPMX and to request more information about borrowing against gold.

What is the Most Common Gold Bar Size That is Bought?

By far the most common size gold bar we sell is the 1 oz gold bar. Why?

Most likely because the 1 ounce gold bar is the best combination of lower premium above spot price, and resale-ability. A 1oz bar is not too high a value. So if buying a number of ounces of gold you can sell them later in tranches.

(Tip: If you want even greater divisibility then consider buying silver coins.)

Other Factors to Consider When Buying Gold Ingots and Bars

Different Brands of Gold Bars

There is a vast range of brands available when buying different types of gold bars. These include local New Zealand refined gold brands and overseas brands.

Overseas refiners include:

• PAMP
• Argor-Heraeus
• Johnson Matthey
• Metalor
• Scottsdale Mint

Overseas options also include sovereign mints such as:

• Perth Mint
• Royal Canadian Mint
• US Mint

Again there are pros and cons to buying locally refined New Zealand made gold bars and imported/overseas made gold bars. This article covers these advantages and disadvantages in detail: PAMP Suisse Gold / Silver vs Local NZ Gold / Silver: Which should I buy?

Regardless of what gold bar you buy, there are a few things you should expect to see on it.

The refiners hallmark should be cast or stamped into the gold bar. Also clearly visible should be the purity of the bar. Generally this will be 9999 purity or 99.99% pure. Some larger bars (1 kilogram and 400 ounce) may only be 999 pure. Finally the weight in either grams, ounces, or kilograms.

Some brands and sizes may also be cast or minted with a unique serial number. Some may also ship with certification. Generally you will also pay more for these types of bars.

No GST on Gold Over 99.5% Pure

This point is generally not of concern when buying different types of gold bars as almost all are 999 or 9999 pure. However some coins such as the South African Krugerrand and American Eagle 1oz gold coins are only 22 carat or 91.67 pure. These 22 carat gold coins therefore attract GST in New Zealand and so are not a great buy here.

Cast Bars vs Minted Bars

What is a Gold Cast Bar?

A cast bar simply means the gold has been melted and then poured into a cast or mould. This cast will have the refiners hallmark stamped into it along with the weight and purity.

A cast bar may also be referred to as a moulded bar, poured bar or a gold ingot. The word ingot and bar are often used interchangeably. See: 1oz Gold Cast Bar

What is a Gold Minted Bar?

Whereas a minted bar is produced in a similar way to a coin. There are multiple steps involved. There is still a casting process to produce a bar of a certain size. But then the bar is fabricated via a striking process. A machine strikes the bar – effectively stamping it with a design much like a coin is. See: 1oz Gold Minted Bar

Pros and Cons of Cast and Minted Bars

Cast bars are cheaper to produce, therefore are cheaper to buy. They can also have some variation between bars due to the casting process. However this comes down to personal preference. Some people prefer the individuality of a cast bar, while others prefer the exactness of a minted bar.

Minted bars have more detail in their design. The minting process is of course what gives the minted bar a higher price compared to a cast bar. While you may pay more for a minted bar there is also no guarantee you will get more for it when you sell it, compared to a cast bar. Minted bars usually come in packaging, so if you’d like to handle your gold bar, a cast bar may be a better option.

How Gold Bar Prices Have Changed Since 2022

Gold prices have risen dramatically since 2022, pushing the cost of larger bullion bars much higher for new investors. As a result, affordability and flexibility have become increasingly important considerations when deciding what type and size of gold bar to buy.

This sharp rise in gold prices is one reason many first-time investors in 2026 are starting with fractional gold bars or silver bullion before gradually increasing their precious metals holdings over time.

Gold Bars Stand the Test of Time

Gold bars are a popular way to protect purchasing power and guard against financial crises. They are an asset that has stood the test of time for millennia. The prices above show that gold bars have given protection against the high inflation of the past few of years.
