The programme follows a trial of the scheme in Counties Manukau.
With nearly 5000 smokers on the West Coast, the district health board decided it was time to act.
Expectant mothers can now be referred by their midwives to smokefree counsellors who can offer them fuel vouchers each week they do not light up.
The scheme's trial in south Auckland resulted in a 65 percent quit rate - more than double the average for regular stop smoking programmes.
West Coast smoke-free services co-ordinator John Caygill said even when a woman discovered she was pregnant, she could still find it incredibly hard to kick the habit.
