New measles cases have been confirmed in Auckland, bringing the total number of cases in the region to 15.
The update, from the Auckland Regional Public Health service, came at 2.00pm on Monday.
Information about the cases – whether they were linked to existing cases, or where those people went while infectious – was not yet known.
A spokeswoman for the health service says that information would be released on Tuesday morning.
Last week there were 12 confirmed cases.
Of those, three contracted measles overseas, seven were close contacts of a case, one came from Christchurch, and one contracted measles from an unknown source, ARPHS says at the time.
Measles is a serious, highly infectious viral illness. It can be life-threatening.
Symptoms of measles include a fever, cough, runny nose, sore red eyes and white spots inside the mouth. After three to five days a rash appears on the face and then moves down the body.
