Three Bay of Plenty people, including two children, have been hospitalised with meningococcal infections.
A Bay of Plenty public health official says people should stay alert to the symptoms after three cases of the disease were reported in the region over the holiday period.
One was a 5-year-old boy who had recently moved to Tauranga from Northland, a region that has been in the grips of an outbreak of the deadly Meningococcal W (MenW) strain, prompting a Government vaccination campaign.
An Auckland District Health Board spokeswoman said the boy was in a stable condition in Starship Hospital.
An 8-year-old Te Puke girl from the boy's extended family was in a stable condition in Tauranga Hospital, a Bay of Plenty District Health Board spokeswoman said.
