Smoking rates among Te Arawa Maori have dropped significantly, but there's still a lot of work to be done to get them closer to the national average, say anti-smoking groups.
According to 2013 census results Te Arawa Maori smoking rates dropped almost 10 per cent compared with 2006 results.
Between 2006 and 2013 the number of regular Te Arawa smokers dropped from 10,338 (38.5 per cent of iwi) to 8376 (29.3 per cent of iwi) with the number of Te Arawa Maori saying they had never smoked increasing from 10,014 to 12,447.
The national average for Maori smoking dropped from 37.6 per cent in 2006 to 29.3 per cent in 2013.
According to the National Maori Tobacco Control Leadership group, Ngapuhi, New Zealand's largest iwi, saw the biggest drop in numbers of regular smokers with a decrease of 9.9 per cent followed closely by Ngati Tuwharetoa and Tuhoe.
