Sudden death rates for babies in Northland have halved but Maori infants still make up more than 90 per cent of overall deaths.

Statistics in a new report by the Child and Youth Mortality Review Committee (CMRYC) found from 2002-2015 Maori babies in Northland were slightly over six times more likely to die from SUDI than non-Maori, with 52 of the 57 babies (91.2 per cent) who died over those 13 years of Maori descent.

However Northland District Health Board (NDHB) statistics show the average number of SUDI deaths had halved with an average of six to 10 SUDI deaths per year five years ago compared with an average of two to four SUDI deaths per year now.
