This feasibility project tested the effectiveness of using Māori voluntary community health workers (“Aunties”) to identify and reach Māori pregnant women who smoke and provide cessation support. The majority of women were Māori, 20–30 years old, had their first cigarette within 30 minutes of waking and 58% had not tried to quit during the current pregnancy. Of the participants who completed a follow-up interview, 33% had stopped smoking while they were pregnant and 57% had cut down. At the follow-up interviews, the number of women who had used cessation support or products was increased from baseline.
