Doctors, emergency departments and the general public are being urged to be on high alert after an increase in the number of people contracting the potentially deadly meningococcal disease.
So far this year six people have died from a new strand MenW - and three of those were from Northland.
The Ministry of Health has this week warned GPs and emergency departments to act swiftly if people presented with possible symptoms of meningococcal disease.
The public is also being told to familiarise themselves with the symptoms, which can initially appear like flu-like symptoms. Those with possible symptoms should seek medical attention immediately.
Director of Pubic Health Dr Caroline McElnay said the number of cases of meningococcal disease has risen steadily in the past in the past five years.
