Measles outbreak update – Thursday 4 December 2025  

Today, we are confirming one new case of measles. The number of known measles cases nationally is now 28, of whom 22 are no longer infectious.

This case is in Wellington. We are also updating our locations of interest page (external link) with more known locations following the confirmed cases this week. This  page is updated regularly, and we encourage people to check the page and follow the advice for close or casual contacts, and to monitor for symptoms of measles.

The National Public Health Service is also working to establish any links between the latest measles cases and any known cases or locations of interest. 

While our case investigations including genotyping are continuing, it is highly likely based on our information to date that several of the cases confirmed yesterday can be linked back to the exposure event at Auckland Airport Domestic Terminal on Monday 17 November between 4:00am and 9:30am.

We encourage anyone who may have been in Auckland Airport Domestic Terminal on that date to monitor for symptoms and follow the advice on our Locations of interest page. 

As we head into the summer holiday season, we are especially encouraging people to check their immunisation status (external link) and get their MMR vaccination if required. Measles can have a long incubation period and is highly contagious, so anyone planning to travel, either internationally or within New Zealand, is encouraged to check their immunisation status and get vaccinated if needed.

The National Public Health Service continues to investigate possible links between all known cases and to trace all contacts.

Anyone who develops symptoms of measles, including runny nose, fever, cough,  and sore red eyes, and a rash starting at the face, should contact Healthline on 0800 611 116, or their usual healthcare provider.

Get protected before you travel  over the holiday period 

Health NZ is reminding anyone with overseas travel plans over the holiday period to check their immunisation status and to catch up on any missed MMR vaccination as soon as possible before leaving New Zealand.

Two doses of the MMR vaccine (after the age of 12 months) protect about 99 per cent of people from getting measles. 

Some countries may require proof of immunisation, please check the SafeTravel website for more information, here: SafeTravel (external link)

Allow time before you travel

It can take two weeks to develop immunity after a dose of the MMR vaccination and two MMR doses (after the age of 12 months) at least a month apart is required for full immunity.

Monitor for symptoms

Health New Zealand is reminding people who have recently returned from overseas travel or have whānau visiting from abroad to monitor for measles symptoms and follow public health advice.
