While it's hard to know exactly how much the iPhone 8 will cost Kiwi customers, it's expected to be at the top end of the price scale.
Samsung's new Note 8 will cost $1599 when it goes on sale in stores in New Zealand on September 22.
The iPhone 7 Plus is on sale from $1429 currently.
Apple will announce its official release date today, but devices are usually on sale in its online store about a week after the event.
Demand for the iPhone 8 is expected to be huge and some reports have suggested Apple will struggle to keep up with demand, meaning some customers might have to wait until the end of the year to get their hands on the phone.
