The country’s borders will initially open to New Zealand citizens and visa holders coming from Australia.

This will be followed by visa holders from the rest of the world and finally all other fully vaccinated travellers from the end of April.

Arrivals will be tested on arrival and will have to self-isolate for seven days, although they will not have to complete this at a managed facility.

Covid response minister Chris Hipkins said the phased reopening plan would reduce any potential impact on vulnerable communities and the country’s health system.

“Closing our border was one of the first steps we took to keep our country safe from Covid-19 and it will be one of the last things we do in terms of opening up,” said Hipkins.

"We know the international restrictions we have had around our border have been tough for many people.”

The first phase will get under way from 16 January and the second from 13 February. Fully vaccinated foreign travellers will be the last group to be granted entry, starting 30 April.

Travellers must test negative prior to departure and be able to provide proof of full vaccination against Covid-19.

They will also have to sign a declaration about their recent travel history, and submit to a test on arrival, seven days’ self-isolation, and another test before leaving isolation.
