The trans-Tasman bubble was set up so people could fly from New Zealand to Australia without needing to spend 14 days in a hotel.
However, Australia's expert medical panel made a decision late on Sunday night to change the system.
It means any New Zealanders that fly into Australia from Monday will have to spend a fortnight in hotel quarantine.
The new rule will remain in place for the next three days before the situation is reassessed.
