A quit smoking programme that gives out gift vouchers to pregnant women kicking the habit is being extended.
The Counties Manukau DHB trialled the programme, giving participants petrol and grocery vouchers.
Eighty-nine women enrolled, and after three months, 50 of them had quit smoking.
The Ministry of Health's giving the DHB an extra $400,000 to expand the service in south Auckland.
A number of other DHB's across the country are picking up the programme.
