The MidCentral District Health Board has issued a caution to those who attended the regional Tainui Waka Kapa Haka Festival held on Saturday April 16 at the Claudelands Event Centre in Hamilton.
About 5000 people attended the event and authorities say they may have been exposed to measels, after one
person was subsequently diagnosed.
MDHB medical officer of health, Dr Rob Weir, said anyone who had been to the event should keep an eye out for symptoms until April 30.
"Measles symptoms initially include fever, runny nose, cough and sore red eyes. After three to five days a rash appears on the head and spreads down the body. "
He said anyone who thinks they may have the disease should avoid public places and work.
