New Zealand Prime Minister Jacinda Ardern said on Monday the country will move into a system of living with the COVID-19 virus later this week despite the new Omicron variant posing a fresh health threat to the world.

There were no cases of the Omicron variant in New Zealand at this stage but the developing global situation showed why a cautious approach was needed at the borders, she said.

"Omicron is a reminder of the risk that still exists at our borders," Ardern said at the news conference.

New Zealand has some of the toughest border controls in the world and plans to keep borders closed to most international travellers for a further five months.

It also introduced fresh border measures for travellers from nine southern African nation on the weekend, announcing that only citizens from these countries can travel to New Zealand and will have to stay in state quarantine for 14 days.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

Ardern said a lot of evidence still needed to be gathered to know the impact of the Omicron variant.

"It may impact on our vaccines, but it may not. It may be more severe or it may be more mild than Delta … we simply dont know," Ardern said.

Director General of Health Ashley Bloomfield said authorities were looking at whether more needed to be done at the borders to keep Omicron away.

"It’s really just looking to keep it (Omicron) out while we learn more about it," Bloomfield told reporters at the news conference.

New Zealand moves into a new "traffic light" system from Friday that rates regions as red, orange or green depending on their level of exposure to COVID-19 and vaccination rates. Auckland, the epicentre of the country’s Delta outbreak, will start at red, making face masks mandatory and putting limits on gatherings at public places.

New Zealand has had about 11,000 cases so far and 43 related deaths.
