Eight new cases of measles have been confirmed in Queenstown today, taking the total number of those infected to 15.
Six of the new cases in the resort are NZ Ski staff, working at The Remarkables ski fields, with the remaining two primary school aged children.
A Southern District Health Board spokeswoman said the virus had now spread beyond the ski fields and into in the wider Queenstown area, including Remarkables Primary School and the Queenstown Lakes District Emergency Department.
The SDHB are urging people in the area to check their immunisation status.
"If you have already received two measles vaccinations, or have definitely had a doctor-diagnosed measles infection in the past, you are considered immune. Over 99% of people who are fully immunised are protected from measles."
