Another 37 measles cases have been confirmed in Auckland overnight, prompting warnings by a health expert that the city is facing an epidemic.
The number of measles cases are spreading rapidly across the city with the total number of cases in Auckland this year now sitting at 546, according to the Auckland Regional Public Health Service.
ARPHS public medicine specialist Dr Maria Poynter said at over 500 cases it was a "very serious outbreak".
She urged anyone aged between 1 and 50 years old to make sure they had at least one measles vaccination as the ARPHS tried to stop it spreading.
Children under the age of 4 are the most affected, followed by people aged 15 to 29.
