Three cases of Covid-19 in have been found in managed isolation and quarantine (MIQ) facilities, but none are infectious, the Ministry of Health says.
In a statement, the Ministry of Health said there were no new community cases to report.
It said two of the historical cases were newly detected, and one was a previously reported new case that was now deemed historical.
With the recovery of two cases, active cases were at 27. Total confirmed cases was at 2288 and the rolling seven-day average of new cases at the border was at three.
Yesterday, there were two new cases in MIQ.
Travel from New South Wales to New Zealand resumed after midnight this morning despite restrictions extended in Greater Sydney for a further week.
The travel was paused on Thursday after two men tested positive for Covid-19 in Sydney, where authorities are yet to find how they became infected.
The ministry this afternoon said despite the resumption of travel, anyone who was at a location of interest in Sydney at the times specified must follow NSW health advice regarding isolation and testing.
Travellers who arrived in New Zealand and were at a location of interest during the exposure time must immediately self-isolate, and call Healthline on 0800 358 5453 for information about when to get tested, it said.
After a pre-Budget speech this morning, deputy prime minister Grant Robertson said the government would not be waiting until everybody had their vaccine to open up to other countries.
"Where we can safely open the borders up for the movement of people, we will do that. We will continue to look for opportunities to do that, particularly in the Pacific, where obviously there hasn't been a lot of Covid. But one of the things that gets a little lost there is that we don't want to be the exporters of Covid to the Pacific," Robertson said.
"I caution people against people from thinking it'll flick back to normal [like] there'll be some sort of switch, it's going to take time."
A vaccine passport would be an important part of border developments into 2022, he said.
