The data, released by the coroner last year, was included as part of a comprehensive study on children and injuries by Safekids Aotearoa, part of Starship Children's Health. The goal of the organisation was to help reduce the high rates of preventable injuries to children.
Northland DHB spokesperson Jeanette Wedding said health inequalities, transient population, overcrowding, the poorest roading and high deprivation was why the Northland death rate was so high.
"Persons and households experiencing low incomes, low levels of education and under-employment are less likely than others to have access to affordable housing, or to have the ability to secure a good quality of life for themselves and their families, now and in the future," she said.
Ms Wedding said it was inappropriate to compare Northland to other regions because each region has different factors. For example, metropolitan areas vs urban/rural have different risk factors brought about by their environments.
"Given the rate was calculated from 2006-2010 data, a lot has been done since then to address the number of possibly preventable deaths," Ms Wedding said. That included a comprehensive safe sleep programme, paediatric outreach nurses and a first 2000 days initiative aimed at ensuring no child was left behind.
Included in the study was the number of children admitted to hospitals in Northland with injuries - 1689 between 2008 and 2012.
Like elsewhere in the country, the most common injury was from falls.
Safekids Aotearoa Director Ann Weaver said the figures released in the report were alarming.
"All DHBs need to do their part to ensure children enjoy a life free from the adverse effects of unintentional injury and that they grow to their full potential," Ms Weaver said.
The organisation had created tables for each DHB to be used as a quick and easy guide to understanding current child injury trends.
Just behind Northland in terms of rate of death from injury was Hawke's Bay DHB, with 38 deaths, and Lakes Region DHB, with 25.
