People arriving in UK must spend two weeks in quarantine or pay $2000
"We are introducing these new measures now to keep the transmission rate down and prevent a devastating second wave," she said.
The new quarantine rules will also see passengers fill in a digital form providing their contact and travel information so they can be traced and potentially face random checks from public health authorities.
Those who flout the new rules will face a fine of $2000.
As the death toll climbs to more than 36,300 the government said the new rules wouldn't have had an impact when the virus was already circulating widely but now, after lockdown, new infections from abroad are problematic.
There will be exemptions for road haulage and freight workers to ensure the supply of goods is not impacted, medical professionals travelling to help with the fight against the virus and anyone moving from Ireland, the Channel Islands and the Isle of Man.
The measures will be reviewed every three weeks. ■
