28 cases, up to 1000 close contacts to be tracked
Director-General of Health Ashley Bloomfield says there is still no evidence of community transmission in New Zealand, Bloomfield says.
The Ministry of Health is working to identify any close contacts.
None of the new eight cases are school students.
"We are obviously alert to all the new cases and identifying any close contacts," Bloomfield said.
The Ministry of Health is contacting up to 1000 close contacts of the 28 confirmed cases.
Healthline will be provided with the details for the people considered close contacts from being on the flights with the new eight cases.
Bloomfield said he hasn't heard any official word on a full national lockdown, like in Italy.
"We are planning for a long-term effort here," Bloomfield said.
Bloomfield said he didn't have a timeframe for when New Zealand will experience community spread.
"We are watching very closely as to whether we have any community spread. We also want to act before we see any evidence of widespread community outbreak.
"We've seen a big increase in the number of tests being done, only a few of those cases are testing positive, but it does give us a good idea of whether there's wider community transmission. We're testing people with wider influenza symptoms and it's not at this point been Covid-19.
"There's a lot of work going on to confirm our labs have everything they need to conduct the tests, get the results out quickly, identify the positive results and contact trace."
