A new iPhone launch always brings the same question: is now the time to upgrade? This year, Apple has given people a little more to think about.
Alongside the new iPhone 18 range, Apple has unveiled iPhone Duo, its first foldable iPhone - a passport-sized device when closed that opens to reveal a 7.6-inch display. It’s a significant change to a product that Apple has spent years refining rather than reinventing, and perhaps the clearest sign yet that the shape of the smartphone is changing.
But whether you have your eye on the latest iPhone, want the power of an iPhone Pro, or are simply wondering whether this is the year to replace the iPhone already in your pocket, there’s another question worth asking: How much could your next iPhone actually cost you?
Save up to $1,750 on your new iPhone at One NZ
Right now, you can save up to $1,750 when you pre-order on interest free with a monthly One Plan and trade in an iPhone 17 Pro.
And if you have Phone Dollars available, you could potentially get an even better deal.
Your trade-in can help bring down the cost of your new iPhone. The One NZ offer can bring it down further. And if you've already earned Phone Dollars, you may have additional value ready to put towards an eligible interest-free phone.
So before deciding what your next iPhone will cost, it pays to look at everything you have available.
The new iPhone Duo is a big change for Apple
Apple isn't normally a company that changes the fundamental shape of the iPhone just for the sake of it. That's why iPhone Duo is interesting.
It's Apple's first foldable iPhone. Closed, it has a 5.4-inch outer display and is similar in size to a passport. Open it and you get a 7.6-inch inner display - the largest display Apple has put on an iPhone.
The extra space isn't just about having a bigger screen. Apple has reworked iOS 27 around the foldable format, including the ability to use two apps side-by-side with Split View. The folding design also introduces new ways to take photos and video, while Apple's A20 Pro chip powers the device.
In other words, this feels less like making the familiar iPhone a little faster and a little better and more like Apple asking what else an iPhone could be.
For some people, that will make iPhone Duo the device to watch. For others, the more familiar iPhone 18 and iPhone 18 Pro models may still make more sense.
Either way, a new generation arriving is a good reason to look at what your current iPhone is worth - and what value you might already have towards an upgrade.
Your old iPhone could help pay for your new one
Trade-in is one of the simplest ways to reduce the cost of upgrading.
Rather than leaving your previous iPhone sitting in a drawer, its eligible trade-in value can go towards your new device.
It's also an important part of One NZ's current iPhone pre-order offer: save up to $1,750 when you pre-order on interest free with a monthly One Plan and trade in an iPhone 17 Pro.
But trade-in isn't necessarily the only value you can put towards your next phone.
Already have Phone Dollars? Your deal could get even better
Phone Dollars are One NZ's currency that give you real money off your next eligible interest-free phone. One Phone Dollar equals $1 towards your next eligible phone. Depending on the offers available to you, Phone Dollars can be earned in a number of ways - including through eligible One NZ services, connections, trade-in, roaming and special Phone Dollar offers.
They're held in your One Wallet until you're ready to use them towards an eligible interest-free phone. So if you're looking at a new iPhone, it's worth checking your balance before you buy.
Have $200 Phone Dollars? That's $200 you may be able to put towards your next eligible phone.
Have $500? That's $500.
And if you've built up more, you could have even more value waiting for you.
Think beyond the advertised iPhone deal
When people search for the best iPhone deal, it's natural to compare the headline price or discount.
But with One NZ, there's another way to think about it: start with the iPhone offer, then look at what your current iPhone could be worth as a trade-in, then check how many Phone Dollars you already have. Because the question isn't only: “What's the deal on the new iPhone?”, it's also: “What's the best iPhone deal I can get with the value I already have?”. For eligible customers, those can be two quite different numbers.
Thinking about upgrading your iPhone?
Whether the new foldable iPhone Duo has caught your attention, you're considering an iPhone 18 or iPhone 18 Pro, or you've simply been waiting for the right time to upgrade, check what your current phone and your Phone Dollar balance could do for you.
Save up to $1,750 when you pre-order on interest free, with a monthly One Plan and trade in an iPhone 17 Pro. And use your Phone Dollars for a potentially even better deal.
Before you pre-order, check your Phone Dollars in One Wallet. You might have more towards your new iPhone than you think.
