Victoria has reported five new local cases of COVID-19 and two cases reported in managed isolation.
There are 45 active cases overall as the state faces it's second day of lockdown.
In the past 24 hours, 56,624 results were received - a record number.
Another 21,626 vaccinations were given.
New Zealand's quarantine-free travel bubble with Victoria was paused and extended for a further seven days until Thursday night.
"We have been monitoring Melbourne very closely and we have made the decision based on the recent decision by Melbourne to do a lockdown," COVID-19 Response Minister Chris Hipkins said on Thursday.
"We are considering whether further restrictions should be put in place. That includes things like pre-departure testing and whether that should apply, and if so to whom."
Director-General of Health Dr Ashley Bloomfield is requiring everyone who has visited the Greater Melbourne area since May 20 to isolate at home until they receive a negative test.
