"It is really important that babies get that first immunisation on time."
Further childhood immunisations are required at 3 months, 5 months, 4 years and 11 years to ensure ongoing protection.
Since September 2016 there have been more than 1000 cases of mumps reported in New Zealand. While most of these cases have been in the Auckland region, holiday travel increases the likelihood of mumps spreading to other parts of the country.
Dr Miller said it was important to check immunisation statuses with a GP or practice nurse before traveling abroad and book in a vaccination if required.
Mumps is very infectious, and spreads from person to person by coughing and sneezing, or through contact with infected saliva. Symptoms appear about 2 to 3 weeks after coming into contact with someone with mumps.
"Vaccination is the best protection against mumps. If you or your children have not had the recommended two MMR (Measles, Mumps, and Rubella) vaccinations, we strongly recommend that you get these up to date," Dr Miller said.
MMR is recommended and free for anyone born after 1 January 1969 and is given to children at 15 months and again at 4 years of age.
