New Zealanders have been briefed with new information about how the Government is handling new cases of community
transmission.
The SMC asked experts to comment on the following:
1. Mask wearing
3. Legal powers
Associate Professor Arindam Basu, College of Education, Health & Human Development, University of Canterbury, comments:
"Masks are excellent for source control, i.e., not passing infection to others. Not so much for prevention of 'getting'
diseases, hence masks should be on whenever people are out and about.
"There is evidence of airborne transmission, so putting on masks is essential in public spaces
"Any mask is good, EXCEPT for those with valves on them. The clue is to wear them properly covering nose, and take care
not to overlap with glasses to avoid fogging.
"Mask wearing needs to be with all other precautions (hand wash/cough-sneeze hygiene).
"Turn off face-recognition algorithms on phone if wearing masks as they do not work, prompting to take off masks for
some people."

Dr Andrew Chen, Research Fellow, Koi Tū – Centre for Informed Futures, University of Auckland, comments:
“While there are other technologies available, such as Bluetooth-based methods like those we have seen overseas, it is
important that we focus on the tools that are available to us right now.
“Manual contact tracing (i.e. public health officials interviewing active cases and making phone calls to contacts) is
still the primary mechanism through which we are conducting contact tracing.
“The NZ COVID Tracer app is a useful tool to provide a bit more information to contact tracers, and importantly can help
notify you if they identify an exposure risk and there is an overlap with your location logs.
“Keeping your own records through other means is also helpful, and it is worth spending the time to retrace your steps
over the last two weeks, just in case it is needed by contact tracers.
“Bluetooth-based methods (including the Apple/Google protocol and CovidCard) are being actively investigated and
developed by the government, but I expect that this will still take a few months to be rolled out and we should not rush
this process - it is more important to get it right.
“These other technologies are not silver bullets and we have seen limited effectiveness overseas, so we need to think of
these technologies as augmentations/support for the manual contact tracing system.
“Under the recently released COVID-19 Public Health Response (Alert Levels 3 and 2) Order 2020, s16(2)(d) requires that
businesses at level 2 (and level 3) must ‘display a copy of the QR code for the business or service in a prominent place
at or near the main entrances to the workplace’, where the ‘QR Code’ is defined earlier as ‘a unique identifying code
issued by the Government for the purpose of supporting contact tracing’.
“I expect that this refers to the NZ COVID Tracer QR codes - increasing the availability and visibility of these posters
will hopefully improve use of the app and help people keep records of their movements more easily. We have previously
seen that more businesses making QR codes available leads to a corresponding increase in participation, so I hope that
this new requirement will lift the participation rate.
“Businesses can easily generate a QR code through the Ministry of Health using a self-service form.”

Professor John Hopkins, Professor of Law specialising in Law and Disasters, University of Canterbury:
“The unhelpful confusion caused by the weak legal tools which the police and other enforcement bodies had under the
first lockdown has been removed by the CoVID-19 Public Health Response Act 2020.
“This provides a much stronger mandate for such powers. While far from perfect, this act, with its clear authority under
Section 11 will hopefully balance any reluctance by some individuals to follow the rules second time around
(particularly given those earlier rules are current being challenged before the High Court).
“Although, as ever, the legal system which provides the framework for the CoVID-19 response will only achieve its
purpose if the Community self-enforces its requirements. Maintaining that support through strong, clear and fair
decision making will remain crucial in retaining the legitimacy of the response that this will require.”

Dr Hiran Thabrew, Child Psychiatrist and Paediatrician, University of Auckland and Auckland District Health Board:
“Going back to lockdown, albeit half expected, is likely to be anxiety, disappointment and even a sense of grief.
“Anxiety is likely to be related to worries about one’s own safety and the safety of loved-ones and may lead to
avoidance of people and public spaces. This may not be a bad thing. It may also lead to a resumption of searching social
media for COVID-related stories, which is likely to be less useful.
“Disappointment is the psychological reaction to an outcome that does not match up to expectations (i.e. you are in an
uncertain situation, you hope for a positive outcome, you feel you deserve the positive outcome and then you are
surprised that you dd not achieve the positive outcome). The greater the disparity between your expectations and the
outcome, the greater the disappointment.
“Grief can manifest in different ways/stages (although these don’t always happen in a set sequence):denial (this isn’t really happening)anger (acting out/breaking the rules)sadness (feeling down about what’s going on).acceptance (coming to terms with what’s happening and doing what’s needed)
“Those who break the rules are likely to channel the anger and risk exclusion by the rest of the ‘team of 5 million’ who
are trying to survive the situation together. Multiple cases could also lead to people doubting the Government’s
strategy of stamping out the virus and pose a political risk during this election year. Therefore, public vigilance is
essential, not merely reliance on a limited number of regulatory authorities such as the Police.
“Healthy ways to manage anxiety, disappointment and grief include:Revising one’s expectations (again).Focussing on what you can control, and trying to accept what you can’tContinuing to do all the things you did during the previous lockdown to maintain your mental health and care for others,
including:Creating a new daily/weekly routineNot trying to do too much (aim to achieve 70% of what you’d like, not 100%)Talking about your feelings with othersActively using relaxation strategies, including regular exercise, mindfulness via apps like CALM/Headspace, online yoga,
etc.Practicing gratitude by thinking of three things for which you are still grateful each dayLimiting use of social media to read stories about COVID or keep up with the latest case numbersChecking in and staying connected with others, especially those who may be more afraid or more vulnerable to either the
virus or the effects of isolationRemembering that this too will pass
“Note that children may have different responses, depending on their ages. See my previous statements (here and here) for more information.
“However, the most important determinant of how they fare is likely to be how their parents react to the situation. So,
providing age-appropriate explanations of what’s going on, staying calm and modelling self-care strategies will help
them get through this period.
“Following this phase, the public is likely to be open to greater protection measures. More organised or mandatory use
of the COVID tracker app or other tracking technology may be one valuable strategy.”
