A confirmed case of measles in Hamilton has sparked a health warning in the city.
Public health officials say the person caught the disease overseas, before returning to New Zealand.
People who visited the Bunnings store on Kahikatea Drive between 10 and 14 April, New World Glenview on 12 and 13 April, Pak'n Save Clarence Street on 15 April, Anglesea Pharmacy 15 April and Clean As Laundromat on 15 April are potentially at risk.
Anyone who visited those places and felt unwell should call their doctor, rather than visit a clinic, public health officials said.
The people most at risk were those who haven't had the measles, mumps, and rubella - MMR - vaccine.
Measles is a highly infectious disease and people who share the same air as someone while they are infectious may be at risk of developing the disease, if they are not already immune.
The case was not related to a recent measles outbreak in the South Island, public health officials said.
