Ms Marshall said most smokers wanted to stop and referrals from hospital services were increasing. The top reasons for hospital patients deciding to quit were health, money and wanting to be smokefree role models for their children.
Smokers could quit even if they had been unsuccessful in the past, especially with stop-smoking medications, she added.
She said support from a stop-smoking service helped deal with smoking habits and craving for nicotine.
While many Northlanders were successfully giving up, some relapsed because others were smoking around them or due to stress, she said.
"That's why it's important to get help to work through those potential stresses in advance and have a plan in place and to be in the mind-set that 'I am now a non-smoker'."
E-cigarettes were having mixed success and Ms Marshall recommended those using them also get other support.
