Some lawmakers have urged the government to scrap its PCR test requirement for travellers returning from the mainland, to make it easier for Hongkongers to return home after the Lunar New Year holidays.
Currently, people crossing the border into the SAR need to present a negative PCR test result obtained within 48 hours of their trip.
But DAB lawmaker Edward Leung said PCR testing services on the mainland are scarce, especially during the upcoming holiday period.
"Recently we have received a lot of complaints or cases that it is very difficult to find PCR tests on mainland China because it is Chinese New Year now. We believe that it is better to use rapid tests," he said.
Federation of Trade Unions legislator Bill Tang agreed, adding that travellers heading north should also be exempt from the PCR testing requirement.
"The same principle can also be applied on mainland China residents... they can also do a rapid test. No need [for them] to go to a PCR testing centre in Hong Kong," he said.
"Maybe this is useful in solving the problem of long lines at the testing centres."
In a statement, the government called on travellers to make advanced bookings online to avoid long waiting times, adding that it has asked contractors to bolster their manpower at busy testing stations to cope with the increasing demand.
A woman who got her test in Wanchai told RTHK that the whole process took her an hour – much longer than she had expected.
"Even though I have booked online, I had to wait for registration, and then I had to join another line for payment. And after the payment, I had to wait to confirm my information, and after that I could do the test," she complained.
A Mr Deng said it also took him an hour to get tested.
"If I could do it at home [rapid test], it's better... All over the world people can travel freely, I think we can do it, too," he said. "Actually, no more tests. We should be able to go anywhere anytime."
Meanwhile, children aged three or below will no longer have to present a negative PCR test result before they cross into the mainland from Thursday.
In a statement, authorities said the decision was made after discussing with relevant departments on the mainland.
