From Monday, New Zealanders travelling from Australia will no longer have to spend a week in hotel quarantine and can instead isolate at home.
But with Omicron now in New Zealand, Prime Minister Jacinda Ardern said the government is looking at reducing restrictions further.
New Zealand had about 28,000 cases over the weekend, of which 47 were from border arrivals.
"With so many cases in New Zealand now, it makes sense to look at those settings," Ardern told Radio NZ.
"Cabinet will discuss and make decisions today.
"I'll be giving an indication of those decisions at post-cabinet (press conference) this afternoon."
A panel of public health experts will be consulted before the decision.
Possible outcomes would be a shorter self-isolation stay, a shorter timetable to allow more in sooner, or - while unlikely - the abolition of self-isolation entirely.
