A party at home has proven to be a hotbed for measles.
Dr Annette Nesdale, a medical officer of health for the greater Wellington region, confirmed eight people have come down with the infectious disease since attending a party in Lower Hutt last month.
"A man did not know he had measles at the time of the party, and most likely acquired the infection while in Australia."
The Capital and Coast District Health Board has reported three cases from guests at the party and the Hutt Valley DHB has reported five.
"All attendees were in home isolation the entire time they would have been infectious so there's no evidence of community spread beyond the party," Nesdale said.
