Protect yourself and your whānau against measles
Measles outbreak alert: New case in Nelson
21 October 2025
A case of measles has been confirmed in Nelson, and further cases in Manawatu and Auckland.
Te Piki Oranga is working alongside Health New Zealand / Te Whatu Ora and primary health partners in the region to respond to the outbreak of this infectious disease.
Te Piki Oranga advises whānau to check their vaccination status and that of their children, to see if they are protected against catching and spreading measles. Information about this and the measles vaccine (MMR) is on this webpage below.
We also advise whānau to check the locations of interest – where people infected with measles have been in the community, to see if you or your whānau may have been exposed to measles.

Information about measles
Measles is highly contagious and can cause serious illness, but it can be prevented with the measles, mumps, rubella (MMR) vaccine.
Resources: Download our factsheet about measles and the MMR to share or print.
How measles spreads
Measles spreads quickly through the air. You can catch the virus as easily as going into the same room that someone with measles has been in. This is because the virus stays alive for up to two hours on surfaces and the droplets can linger in the air.
The virus is spread via droplets released into the air when an infected person sneezes, coughs and breathes.
Protect yourself and others against measles
The MMR is free and available to anyone born after 1 January 1969.
To find out about vaccination for tamariki, contact our specialist Well Child Tamariki Ora nurses.
Te Piki Oranga also offers the MMR vaccine for ngā pakeke (adults), and support and advice about vaccination.
Check if you are protected against measles
You are immune to measles if you:
Were born before 1 January 1969
Have had measles before
Have had two MMR vaccinations, and the last vaccination was more than a month ago
Pēpi under 15 months are immune if they have had their first vaccination, at least a month ago
Have had a blood test showing you are immune
To find out if you and your whānau are immune, check your vaccination record in your Well Child Tamariki Ora (Plunket) book, or contact your doctor.
If you are not sure whether you have been vaccinated, it is safe to get the MMR vaccine again.
Some people are at risk of serious illness
Some people are more at risk of becoming very unwell if they catch measles. This includes:
Anyone with a chronic illness or a weakened immune system
Tamariki younger than five years old who have not had their first MMR vaccine
Pēpi younger than 12 months who are too young to receive their first MMR vaccine
Wāhine hapū (pregnant women)
If you or your whānau are in these groups, it's even more important you get vaccinated if you can.
Wāhine hapū and tamariki aged 12 months and younger cannot get vaccinated. The exception to this is: During a measles outbreak (an urgent situation), children under 12 months may be able to be vaccinated.
This is why it is important that whānau of wāhine hapū and tamariki have had both MMR vaccines.
If whānau have immunity through vaccination, they are much less likely to catch and spread measles to people who cannot be vaccinated.
Know the measles symptoms
The main symptoms of measles are: A red, blotchy rash; a fever (very high temperature); sore, watery pink eyes; a cough; a runny nose.
About the measles rash (spots)
Measles causes a red, blotchy rash that normally appears three to seven days after the other symptoms. It starts on the face and then spreads to the rest of the body.
What to do if you have symptoms
Seek medical advice urgently on the phone, from your doctor or from Healthline on 0800 611 116 (available all hours).
Please do not visit a medical centre or hospital without calling first as you may risk passing on the virus to others.
When to call an ambulance
Measles can cause severe complications such as pneumonia, encephalitis, or respiratory distress. These require urgent medical attention.
Phone for an ambulance on 111 if someone is:
having trouble breathing
hard to wake or having difficulty staying conscious
becoming floppy or very drowsy
turning blue around the lips or mouth
having a seizure
What happens if you have measles or have been in contact with someone that has measles
If a test shows you have measles, you will need to stay home and isolate from other people.
You will be given personal advice from a health professional who will stay in touch
They will help you to identify anyone else at risk of catching measles from you, and will contact them to let them know what to do (contact tracing).
There is support available if you need to isolate.
Where can find information about the vaccine?
