Rates among M\u0101ori (1.97\/1000) and Pacific (0.91\/1000) infants were higher than those among Europeans (0.17\/1000). 72.3% of cases occurred while direct bed sharing. Maternal smoking was reported in 51.5% of cases, vaping in 30.3%, and smoking and\/or vaping in 72.7%. Vaping was more likely in bed\u2010sharing than non\u2010bed\u2010sharing deaths (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003). Compared with New Zealand studies from 1987 to 1990 and 2012 to 2015, current cases show increasing proportions of M\u0101ori and Pacific infants, older mothers, back sleeping and direct bed sharing.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SUDI rates remain unacceptably high with widening ethnic disparities. The proportion of deaths associated with direct bed sharing is striking and is increasing. Vaping appears to be an emerging SUDI risk factor, especially when combined with direct bed sharing.
