There have been two cases of Covid-19 in managed isolation reported today, ahead of the resumption of flights from Sydney tonight.
In a statement, the Ministry of Health said there were no community cases.
The two new imported cases arrived on Friday from the Philippines and Pakistan.
It said there were 27 active cases and the total number of confirmed cases in this country is now 2286.
The ministry said flights to and from Sydney will resume at midnight tonight, following two community cases reported earlier in the week, as there was no evidence to suggest "widespread, undetected community transmission".
"The current assessment from New Zealand public health officials is that the risk to New Zealand from New South Wales remains low."
It said 5568 people who have arrived in New Zealand from NSW since last Friday have been contacted by health authorities and provided with advice.
