The Ministry of Health strongly recommends boosters for anyone over the age of 18 who had their second vaccine dose at least four months ago.
The ministry is today reporting 43 people at the border with Covid-19. New Zealand continues to see many border cases arriving from overseas, reflecting the growing number of Omicron cases globally.
The seven-day rolling average of border cases is 31.
Omicron update
To date, there are now 266 Omicron Covid-19 cases detected at the border since December 1.
During the same period, more than 18,000 people have arrived and been processed through Managed Isolation and Quarantine facilities
The ministry says New Zealand has taken steps to manage the risk of a community Omicron outbreak linked to border cases, including increasing the period overseas arrivals must spend in MIQ, and shifting the focus of whole-genome sequencing to areas of most risk, such as for any cases in border workers.
