A new case of measles has been found in Queenstown.
The case has no known links to the four cases in Northland.
The new case is likely linked to overseas travel and is currently in isolation, Heath NZ says.
Possible exposure locations and close contacts are still being identified.
High school production a location of interest in Northland cases
There are four cases of measles in Northland.
While they are no longer infectious people are being urged to monitor for symptoms such as a fever, cough, runny nose, sore eyes and rash.
A new location of interest has been identified as the Kerikeri High School "Monsters" production on September 17 at 7pm.
"If you were at this event and have not been contacted by public health, please call Healthline on 0800 611 116 urgently. It is also important you stay home until you have received advice as you may be infectious and could be at risk of passing measles on to others within your community," National Public Health Service national clinical director of protection Dr Susan Jack said.
Anyone at the event needs to stay home in quarantine until 8 October if they are not considered immune to measles, which will need to be checked by public health.
At any time, if you develop symptoms of measles, contact your healthcare provider or call Healthline on 0800 611 116 for free advice 7 days a week, 24 hours a day.
Immunisation
Te Whatu Ora says getting immunised with two doses of the Measles, Mumps and Rubella (MMR) vaccine (after the age of 12 months) is the best form of protection against measles.
You can do this at a pharmacy, doctor, nurse or hauora provider.
It is free for anyone 18 years or under, and for people who are eligible for free healthcare.
A Kaikohe Plunket immunisation clinic is available Tuesday
