Measles symptoms include a high fever, runny nose, cough and sore red eyes. A few days later a rash starts on the face and neck, before spreading to the rest of the body.
Poynter said "You are most at risk if you're not immune to measles, either because you haven't been vaccinated or you haven't had the disease previously.
"People who are not immune may start experiencing symptoms over the next week."
Anyone over the age of 50 years is considered immune as they would have been exposed to the virus as a child.
Other passengers should check their Well Child or Plunket book for at least one measles mumps and rubella (MMR) vaccination.
If you were on the flight and are unsure whether you're immune to measles, talk to your doctor or call Healthline on 0800 611 116 for advice.
