Fly Buys website crashed overnight after the latest iPhone 11 was being rewarded to customers for only 805 points - or at least 50 points and $140.
Thousands of Kiwis jumped onto the website to get the 512GB Apple iPhone 11 Pro Max, worth $2849, after the "crazy deal" was shared on social media including local Facebook groups and Reddit.
The page showed the product being sold for 805 points, or customers could choose to use the points they have and top it up with their own money.
In comparison, on the same page customers could get the 256GB iPhone 11 Pro Max for 17,955 points.
People accumulate Fly Buys points by shopping at the loyalty scheme's partners. For example, a $25 spend at New World earns 1 Fly Buys point.
