The case was thought to be linked to recent international travel and had no known connection to cases reported in Northland, Health New Zealand Te Whatu Ora national clinical director, protection National Public Health Service (NPHS) Dr Susan Jack said.
There are now five known cases of the highly infectious disease in New Zealand, believed to have come from recent, but separate, overseas trips.
The person in Queenstown was isolating and the NPHS Southern was identifying any close contacts and possible exposure locations.
The four cases in Northland were finished with their infectious periods.
However, people in the community were urged to continue monitoring themselves for symptoms.
Dr Jack said the NPHS was co-ordinating responses and working as quickly as possible to reduce any possible spread.
"We are also urging people to get immunised, especially if planning international trips during this school holiday period."
Measles symptoms include a high fever of at least 38°C, a cough, runny rose, sore red eyes and a rash that begins on the face and gradually spreads down the body to the arms and legs.
The rash lasts for up to a week.
"If you need to visit a healthcare facility, call first and tell the healthcare professional that you have been in close contact with a person with measles," Dr Jack said.
