There are 18 community cases of Covid-19 today and one case in the Bay of Plenty that is under investigation.

The Bay of Plenty case originally tested positive while in Waikato, but has a Bay of Plenty address.

The Ministry of Health says the case remains under investigation and will be transferred to Waikato's case total.

Of the other new cases, there are 11 in Auckland, four in the Waikato and two in Canterbury.

There are 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, says the ministry.

The seven-day rolling average of border cases is 31.

The Ministry says forty five percent of the population currently eligible have now received their booster shot.

'We are strongly recommending boosters for anyone over the age of 18 who had their second vaccine dose at least four months ago.”

Omicron update

To date, there are now 266 Omicron Covid-19 cases detected at the border since 1 December.

During the same period, more than 18,000 people have arrived and been processed through Managed Isolation and Quarantine facilities

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.

The MIQ system exists to catch cases at the border. Managed isolation and quarantine facilities are well set up to care for Omicron cases and protect the community. The staff at facilities are experienced in managing and caring for positive cases.

All Managed Isolation and Quarantine facilities follow very strict Infection Prevention and Control (IPC) measures developed by the Ministry of Health to manage the risks of spreading Covid-19. People in MIQ undergo regular routine testing.

All travellers arriving into New Zealand require a pre-departure test. Travellers must receive their test 48 hours prior to travel. Travellers also must complete four tests while in managed isolation. This testing regime provides an extra level protection to our existing border measures.
