The Prime Minister's former chief science advisor has called for an "extreme shutdown" amid New Zealand's escalating COVID-19 outbreak.
Sir Peter Gluckman, who served as the inaugural Chief Science Advisor to the Prime Minister of New Zealand from 2009 to 2018, claimed a nationwide lockdown would be "the best thing New Zealand could do" in a tweet on Monday.
"The evidence is mounting that the best thing NZ could do is make the hard decision to go to extreme shutdown now," Gluckman wrote.
"The number of new cases coming from offshore means community transmission will get established without absolute precaution."
"I think New Zealanders have to understand that the Government has some tough decisions to make... the earlier the tough decisions are made, the more likely we are to maintain control over this raging pandemic globally, which we are no longer immune from," Gluckman told Newshub on Monday.
"New Zealanders are not taking this seriously... social distancing is incomplete, social functions are still happening, restaurants are full, access to sanitisers is patchy... in a funny way, the worry will be left if we go into complete shutdown and get a grip on the situation.
"I think public panic will be settled if we move to a higher level of alert... certainty and a strong Government is what people want when they're scared."
Gluckman reiterated that people want security, something that can be achieved by a complete lockdown.
"Severe lockdown will be comforting rather than threatening. This is a very dynamic situation, but it's no use going into lockdown if we don't think about the issue of quarantining new people arriving in New Zealand," Gluckman explained.
"There have been too many anecdotal cases of people arriving in New Zealand and not going into proper self-quarantine... early, sharp, tough measures are the only way to get some sort of control."
On Saturday, Gluckman also encouraged social distancing between family members to ensure the elderly, who are at a greater risk, don't contract the virus.
Gluckman also retweeted a post by New Zealand nanotechnologist and science educator Dr Michelle Dickinson, urging Kiwis "to take COVID-19 seriously".
"Last night in Auckland the bars & restaurants were full, I’ve watched handshakes happen in meetings & people not wash their hands before eating. This is on us. The virus spreads because of us. We are the ones who can #stopthespread," Dickinson tweeted on Saturday.
Gluckman's warning follows the Teaching Council of Aotearoa New Zealand's call for the closure of schools as the country's case toll continues to climb.
Cabinet is meeting on Monday morning to discuss the next steps to fighting the novel coronavirus, which has infected 66 people nationwide.
Prime Minister Jacinda Ardern will address the media at 1:30pm with the latest updates on the outbreak.
New Zealand is currently sitting at alert level two after the four-stage alert system was revealed by Ardern on Saturday.
Alert level one: Prepare
This level applies when COVID-19 is present in New Zealand but contained. Before Saturday, New Zealand was at this phase due to the risk of importing the illness and sporadic cases. There were a few cases of transmission within households. In response, some border measures were introduced, contact tracing began, self-isolation for the infected and their close contacts was required and limits were put on mass gatherings.
The public was encouraged to consider limiting their exposure to others through physical distancing and staying home when feeling unwell. Key messages of preventation began to be frequently communicated.
Alert level two: Reduce - New Zealand's current level
New Zealand moved to this level of Saturday after authorities deemed the likelihood of new cases as high. There has been an increase in imported cases and cases transmitted within households. This suggests that COVID-19 is contained, but the risk of community transmission is growing. Currently, there is no confirmation of community transmission in New Zealand - however, two cases don't have clear links to overseas travel and investigations remain underway.
Under this level, border measures have been increased and more restrictions have been put on mass gatherings. Authorities are now calling for greater physical distancing on public transport, limiting non-essential travel around the country, new ways of working - such as remote working - businesses activating their continuity plans and vulnerable people, including those over 70, to stay at home.
Alert level three: Restrict
Level three would come into effect if authorities believed there was a heightened risk of the illness no longer being contained. This could mean that community transmission is evident or multiple clusters of COVID-19 have broken out. Those regions or centres with clear clusters or community transmission could have their travel limited, public venues and affected educational institutes closed, mass gatherings banned and alternative ways of working required with some non-essential businesses closed.
Changes would also be introduced within the health system. For example, primary care consultations would no longer be face-to-face, while elective services and procedures would be deferred to allow for healthcare staff to be freed up.
Alert level four: Eliminate
This is the top-level and would be activated if it is "likely" COVID-19 is not contained nationally or at a local level. There would have to be intensive and sustained transmission with widespread outbreaks. Under this level, people would need to stay at home, all educational facilities and non-essential businesses closed, supplies would be rationed, facilities would be requisitioned, travel would be severely limited and all healthcare services would be reprioritised.
