New Zealand has extended for eight days a ban on arrivals from mainland China, Prime Minister Jacinda Ardern said on Monday, carrying into its fourth week an effort to block exposure to the coronavirus.

Fears grew that the outbreak would grow into a pandemic with disruptive and deadly consequences for the rest of the world following sharp rises in infections in Iran, Italy, and South Korea.

But New Zealand has no plans, for now, to widen the ban to other countries, Ardern told a news conference, adding, “We continue to focus on the epicenter of the outbreak.”

Ardern added that it was highly likely the virus would eventually arrive in New Zealand, although it has no confirmed infections, Reuters reported.

Finance Minister Grant Robertson said the government would step in to assist businesses hit by the spread of the virus if there is a long-lasting shock to the economy or a global economic recession, but he did not expect one at the moment.

“If either of these scenarios plays out it will be important for the government to play a role to invest in the economy to support New Zealanders and Kiwi businesses,” he added.

New Zealand’s exports to largest trading partner China have taken a major hit, with everything from timber to meat and fruit facing delays and cancellations.

By Sunday, the epidemic had killed 2,592 people with 77,150 infections on the mainland, Chinese authorities said.
