A case of measles has been diagnosed in Taranaki in a traveller recently returned from overseas.
It is the 13th case recorded in New Zealand this year, following recent cases linked to a person from Northland.
The National Public Health Service said health officials have been working to trace people who may have come into contact with the individual during their journey.
A spokesperson said any locations of interest will be posted on Te Whatu Ora's website as soon as possible.
