Senior population health adviser Ana Apatu, who made the presentation, said leadership started with staff.
Staff were expected to tell patients not to smoke in hospital grounds and it was against protocol for staff to smoke while in uniform or while representing the DHB.
Mrs Apatu said the region was on its way to achieving the "aspirational" goal.
Smokefree would mean more than 95 per cent of the population did not smoke and tobacco would be difficult to sell and purchase.
The first steps, in the three years to 2015, included targeting smokers - especially pregnant women - at primary health level; marketing quit services, educating children and using business and Maori leaders in a "whole community approach".
"Being tobacco-free is also the single [best] thing we can do to reduce disparities and inequalities and improve Maori health," Mrs Apatu said.
"We are seeing amazing results with the ASH programme, that shows the Year 10 'never smoked' rate is increasing and that's really exciting.
"We believe the Ngati Kahungunu leadership is really invaluable, we are very fortunate to have an iwi as dedicated to smokefree."
TIME TO QUIT
Tobacco is the single largest preventable cause of illness and early death.
Addiction to tobacco is a chronic and relapsing condition.
Exposure to first, second and third-hand smoke has negative effects on neonatal, newborn and infant health.
Reducing tobacco use is the best opportunity to reduce health inequalities between population groups.
