Face masks are no longer mandatory on public transport in most of New Zealand as Covid-19 cases continue to drop.
From midnight on Wednesday, they are required only in Auckland, the heart of a recent outbreak, and on planes.
The rest of New Zealand lifted all pandemic restrictions on Monday.
New Zealand was widely praised for its swift response to Covid-19 and everyday life largely went back to normal in June, but the virus reappeared in Auckland in August.
The country's biggest city went back into lockdown, temporarily, as other curbs were re-imposed elsewhere.
New Zealand has now recorded 1,468 confirmed Covid-19 cases and 25 deaths.
Why have mask rules changed?
Everywhere except Auckland returned to level one - the lowest of a four-tier alert system - on Monday after seven days of no Covid-19 community cases.
This means life almost as normal - no more social distancing or caps on gatherings such as weddings or sporting events. Everyone can return to work without restriction and wearing a mask is no longer compulsory on public transport.
The government says face coverings aren’t necessary for the general public when there is no evidence of community transmission.
But it is still encouraging people to wear masks on public transport. In Auckland, now at level two, they are still compulsory.
Also, passengers on planes flying to, from and via Auckland - as well as on all Air New Zealand flights - are still required to wear masks.
On Wednesday, authorities reported three new community cases that are not linked to the Auckland cluster. They are connected to a recent chartered flight from Christchurch to Auckland.
Why have masks caused a stir?
Face masks have become one of the big dividers of the pandemic.
Long embraced in many Asian countries, they’ve been resisted by some citizens in the US, Europe and at times New Zealand too.
It only became mandatory four weeks ago to wear facial coverings on public transport at alert level two and above.
Now as most people return to the old normal, top epidemiologists have raised concerns about the dropping of masks.
We’ve argued to "retain mask use in specific situations like public transport and residential care facilities” until there is no community transmission for around four weeks and it’s clear the virus has been eradicated again, said Michael Baker, professor of public health at the University of Otago.
But the epidemiologist, who advises the government on its Covid-19 response, acknowledges the challenge masks pose.
“It gets harder to sustain interest in mask use when people think there’s no virus any more. We don’t have masks ingrained in our culture. And I think people have not got used to them at any point,” he told the BBC.
On Monday New Zealand Prime Minister Jacinda Ardern, who has championed social distancing and masks, apologised over a maskless selfie with supporters last week, admitting she made a mistake.
What are other nations doing?
More than half of the world’s countries have issued nationwide mask mandates to curb the spread of Covid-19, said the Council on Foreign Relations, a US-based think tank, in early August.
Vietnam was among the first to introduce compulsory mask-wearing in March.
Taiwan rigorously enforces mask-wearing and extended rules last month. Both places have been internationally lauded for their success in containing the virus with very low caseloads.
In some parts of the world, like Hong Kong, wearing a mask while sick was already a cultural norm after the deadly 2003 Sars outbreak.
But face coverings have also ignited fierce debate. In the US, which has the most recorded Covid-19 deaths in the world, they have become a partisan issue.
Self-described “anti-maskers” have even taken to the streets to protest against mandatory rules.
US President Donald Trump earlier said mask-wearing was a personal choice and has been criticised by experts for his inconsistent messaging.
The shifting advice on masks earlier in the pandemic is also thought to have confused some people about their utility.
At first the World Health Organization and the US Centers for Disease Control and Prevention said there wasn’t enough evidence that healthy members of the general public should wear masks.
But both later advised wearing a mask where social distancing was unfeasible to help curb the spread of coronavirus based on growing evidence.
Dale Fisher, a professor in infectious diseases at the National University of Singapore, said while it was logical for New Zealand to unmask if the virus was eradicated, he questioned how it would respond when the country opened up to the world again.
“It’s wonderful in the short-term. They can go to the rugby, not wear masks, crowd pubs,” he told the BBC.
“But eventually they’re going to have to say we’re opening the borders and we’re going to have cases and clusters.”
No one believes the "fairytale" that there will be a fully effective and fully taken up vaccine so masks "will be an important part of the defence", he added.
