A communicable illness is a disease that can be spread from one person to another. They are also known as communicable diseases.

The Nelson Marlborough Public Health Service has an important role to play in controlling the spread of communicable and notifiable diseases, such as measles and whooping cough.

A notifiable disease is any disease that is required by law to be reported to government authorities. In New Zealand health practitioners such as GPs (doctors) are required under the Health Act to report any suspected cases of a notifiable disease to their local public health service.

Notification allows for appropriate public health control measures to be taken to reduce the risk of further spread, for disease surveillance and for monitoring of the effectiveness of control measures.

Public alerts about disease outbreaks

In most circumstances, any new cases of a notifiable disease in the Nelson, Tasman or Marlborough region will be confirmed with a notice on this website. Local media are often informed and updates are provided through media as well as on this website and our Facebook page:

Measles, Mumps and Rubella (MMR)  Immunisation - why is it so important?

If you’re aged 15-30 you might not be protected against measles. Measles is a serious disease that can make you very sick. It’s much more contagious than COVID-19 so spreads fast!

When you immunise against measles, you don't just protect yourself. You also protect your whānau, your community, and future generations from harm.


Lots of people aged between 15 and 30 years didn’t get fully immunised when they were children. This puts you at risk of catching and spreading measles.

Ask your doctor, parent or caregiver if you had two doses of the measles, mumps and rubella (MMR) vaccine as a child.

If you don’t know, it’s best to get immunised. It’s safe to have an extra dose of the MMR vaccine.

Some other countries only immunise against measles and rubella. So, even if you were immunised against measles overseas, make sure you get your free MMR in New Zealand so that you’re protected from mumps too.


There are good reasons to get immunised:

  • You could get very sick if you get measles: You can have complications like pneumonia, seizures and swelling of the brain. People can die from measles.
  • You might make others very sick if you get measles: Some people can’t have the MMR vaccine because they’re very young or have a disease that affects their immune system. Being immunised means you won’t catch measles and spread it to vulnerable people.
  • If you get measles when you’re pregnant*, it could affect your baby: You may go into labour early or your baby may have a low birth weight. This can have life-long impacts on your baby’s health.* You can’t have the MMR vaccine when you’re pregnant.
  • You could miss out on earning, learning or having fun: If you haven’t had the MMR vaccine and are in the same room as someone with measles, you will have to isolate for up to two weeks. This is to make sure you don’t have measles and can’t pass it on to others.
  • We recently had a measles outbreak: In New Zealand, more than 2,000 people got measles in 2019. 700 had to go to the hospital. Māori and Pacific peoples were particularly affected. We need 95 per cent of people to be immune to reach ‘community immunity’ (sometimes known as ‘herd immunity’) and help stop future outbreaks.
  • Measles is only a plane ride away: Measles is still common in many countries. People can bring it into New Zealand without knowing. You could also be exposed if you travel to certain countries overseas

The Health Navigator website has good information about these serious diseases. There is information in Te Reo Māori, Tongan, Samoan and other languages:

The measles immunisation is called MMR and protects you against three serious diseases: measles, mumps and rubella.

In New Zealand, children are given their first dose at 12 months and their second dose at 15 months (from 1 October).

How does the vaccine work?

The MMR vaccine works by helping your body make antibodies that fight measles.

MMR is given as an injection in your arm. When you’ve had the MMR vaccine, your immune system will recognise and fight the measles virus if you come into contact with it for real.

This protects you – and those around you – from getting sick or spreading measles.

What’s in the vaccine?

The MMR vaccine is made of small amounts of weakened forms of the measles, mumps and rubella germs. These trigger your immune system to make antibodies to fight the germs.

The vaccine has a few other ingredients to keep it stable and ready to go. These ingredients are in tiny amounts and are also found in common foods and drinks.

All vaccines approved for use in New Zealand have a good safety record and have ongoing safety monitoring. Go to the Ministry of Health's webpage about vaccine safety and vaccine ingredients to help you make an informed decision about immunisation. 

MMR vaccine safety

The MMR vaccine has an excellent safety record. MMR vaccines have been used in New Zealand since 1990.

The MMR vaccine is very effective. After one dose, about 95 per cent of people are protected from measles and after two doses, more than 99 per cent of people are protected.

A small number of people who are fully immunised may still get sick. But they usually get a milder illness than people who haven’t been immunised.

Fewer than one in ten people may get a mild response between five and 12 days after immunisation, like a mild fever, a rash or swollen glands. Other mild reactions that can happen (usually within one or two days of being immunised) include:

  • headache
  • a slight fever (feeling hot)
  • nausea (feeling sick)
  • fainting or feeling faint (eating beforehand helps with this)
  • generally feeling a bit unwell.

The chance of having serious side-effects from the MMR vaccine is extremely rare and would happen within 20 minutes of being immunised. That’s why you’ll be asked to stay for 20 minutes after you have the MMR vaccine. If a severe allergic reaction does happen, the vaccinator can effectively treat it.

Your doctor, nurse or pharmacist will talk about possible reactions with you at the time.


Making an informed decision

Immunisation is your choice. The Immunisation Advisory Centre (University of Auckland) has a lot of good information sources to help you make an informed decision about immunisation. Visit the Immunisation Advisory Centre's website.
