New Zealand government took a drastic measure to slow down the spread of contagion in its initial stages.
Six people are in hospital in a stable condition, one in Rotorua, one in Waikato and three in Wellington. "The Police will monitor them and anyone found violating the order will be fined and quarantined", she said.
People are ordered to stay inside and non-essential services are being shut down, coming as the number of cases rises to 205 today.
Asymptomatic people without the means to self-isolate will also be put in an approved facility, as would those who did not have a suitable way to stay isolated while traveling from the airport to their home city.
Ardern said the travel plans of each person returning would be scrutinised at the border, and said they would be required to transport themselves alone to avoid quarantine.
In a previous press conference, Ardern said the inevitable jump in cases should not be alarm Kiwis.
"We will not get everything right, every time".
Whangaparoa, the military base previously used to quarantine those New Zealanders flown home from the virus' previous centre in Wuhan, China, would be again used for incoming Kiwis. It also provides access to powers that would not normally be available but would be needed to support the delivery and timely response to Covid-19.
Coronavirus: PM to address nation at 8pm today
As of right now, the lockdown will be enforced for 21 days. " Social distancing is the only option to combat coronavirus". He added that "many families will be destroyed forever" if the country doesn't get a grip on the outbreak, CNN reports .
According to the reports, Ardern warned the citizens that the lockdown will be strictly enforced. "Don't think about congregating with anyone else, don't think about a lunch or a catch-up, or visiting a friend in their home", she said.
Ardern earlier declared New Zealand had entered a state of emergency in the House, and addressed the country in a speech. "Your job is to save lives", she said.
Stuart-Black would be empowered by the state of emergency powers, but she said it would be great if she didn't have to use them.
"We will clear people to get home".
Speakers at today's media conference include Director-General of Civil Defence Emergency Management Sarah Stuart-Black, Director-General of Health Dr Ashley Bloomfield, Immigration NZ national manager Peter Elms and MBIE deputy chief executive Paul Stocks.
"Some examples are: Powers of requisition to manage wider consequences, for example, providing for the conservation and supply of fuel and other essential supplies; closing of roads; stopping people doing activities that may contribute to the emergency; excluding people from places; prohibiting or regulating traffic".
