Hong Kong has banned gatherings of more than two people as countries across the world try to control new coronavirus outbreaks.
Authorities reported 145 cases on Monday, a new daily record, of which 142 were locally-transmitted cases.
Authorities allowed restaurants and cafes to function through the day as normal.
More than 2,600 people have been infected with coronavirus in Hong Kong since late January, with 20 of them having died.
The measures in Hong Kong come as Daniel Andrews, premier of Victoria state in Australia, said the biggest driver of new infections there is people continuing to go to work after showing symptoms.
Victoria reported a record 532 cases on Monday.
Melbourne, the biggest city in the state, is almost halfway through a six-week lockdown aimed at curbing community spread of the virus.
Andrews said: “This is what is driving these numbers up and the lockdown will not end until people stop going to work with symptoms and instead go and get tested.”
Australia is among many nations in the Asia-Pacific where foreign travellers are essentially banned or, when allowed to enter, required to submit to tests and strict quarantines.
At the same time, some countries that have let limited international travel resume are reconsidering as clusters of cases grow into new outbreaks.
Some European nations were warning citizens not to visit Spain after some of its most beloved summer venues turned into coronavirus hotspots facing renewed pandemic lockdowns.
Any proof the passenger caught the virus while in New Zealand would come as a big shock to the island nation of five million people.
New Zealand officials said their South Korean counterparts suspect the traveller was infected while transiting through Singapore.
“We have got our contact tracing system kicking into gear though,” health minister Chris Hipkins said.
