The World Health Organisation has said the Omicron strain appears to lead to less hospitalisations compared with Delta, and is less severe in the elderly and very young. But it warned the variant is not mild.
Lowe said the best defence against Covid-19, including the highly transmissible Omicron variant, is to have three doses of the vaccine.
Auckland Pacific-focused health provider The Fono said they were preparing to offer a range of help to whānau isolating at home, from health support from nurses to a welfare team providing food.
The Fono chief operating officer Sally Dalhousie said they have been training staff to pivot into different roles and provide surge support.
"We're looking at being able to redeploy a lot of our social work staff, a lot of our public health team.
"We're fortunate we've got about 50 people who we can send out into the community to provide that additional support across all of Auckland when and as needed."
The Fono will provide a drive-through vaccination clinic in Westgate, and is adding capacity to PCR testing stations.
