Health officials are crediting a mass meningococcal C vaccination campaign in Northland during 2011 with low rates of the disease this year.
Nine confirmed cases of meningococcal C and four of meningococcal B were recorded by the DHB from July to November last year and in 2010 three Northlanders died as a result of meningococcal C.
An emergency vaccination campaign in Northland last year saw 35,000 young people immunised free of charge.
Northland District Health Board medical officer of health Jonathan Jarman said so far this year there has only been one case of meningococcal in the region.
"That's absolutely wonderful," Dr Jarman said.
