Auckland has climbed four spots in the "Top Towns" race to be fully vaccinated against the Covid-19 virus.
The City of Sails, which has borne the brunt of the nearly two-month-long Delta outbreak, now has 86.1 per cent of eligible people with one or both jabs.
There were 56 cases of Covid reported in Auckland yesterday.
University of Otago epidemiologist Professor Michael Baker said he felt uneasy about the "exponential rise" of cases in the city and it was now whether the health system could handle such a large number of hospitalisations.
The Herald is running a "Top Town" initiative as part of our vaccination campaign The 90% Project, which aims to get 90 per cent of eligible Kiwis fully vaccinated by Christmas.
