Northland’s estimated population in 2012 is 159,160, 3.6% of New Zealand’s population. Maori comprise around 32% of the Northland population. Northland’s population is ‘ageing’ because older age groups are increasing in both number and proportion, while those of children and youth are decreasing because of declining birth rates. Significant change in the age structure of the Northland is projected between 2012 and 2026.
Northland’s only true urban area is Whangarei, which contains about one-third of its population. The remainder live in small towns (the largest of which are Kaitaia, Kerikeri, Kaikohe and Dargaville at about five thousand each) and rural areas across the district. Many of these are isolated; it takes over 5 hours to travel from Northland’s northern to southern extremities and up to 2 hours west to east.
Life expectancy for all Northlanders is lower than national averages, with life expectancy for Maori in Northland lower than that of non-Maori as too compared with the national Maori population figures. The health risk factors for the population in Northland are: tobacco use, nutrition, physical activity, alcohol use and diabetes, cardio vascular disease and cancer.
