Eight confirmed cases of mumps have recently been reported in school children in Dargaville.
With the school holidays approaching and Auckland in the grip of a mumps outbreak, health officials are calling for parents to keep their children up to date with immunisations and check their vaccination status.
Northland had 10 cases this year before the Dargaville cluster, but Auckland is grappling with its worst mumps epidemic in two decades.
More than 450 cases have been registered there this year, that number surging in the last month.
Meanwhile, there have been 48 notifications of whooping cough in Northland so far this year, compared to nine cases in 2016 and 36 in 2015.
