The Prime Minister says a trans-Tasman bubble is a while away in the wake of an explosion of Covid-19 cases across the ditch.
Melbourne has recently gone into a "stage four" lockdown similar to New Zealand's Alert Level 4 after the state of Victoria had a large number of cases where the source is not yet known.
Overall Australia currently has 6591 active cases.
Ardern told Morning Report the surging numbers are a big setback for the trans-Tasman travel bubble.
