The Prime Minister has indicated the Government may raise the excise tax on tobacco to get people off the smoking habit.
A survey out last week found that nearly 50 percent of people would favour a complete ban on tobacco.
John Key says a total ban would be difficult to enforce, and he says research shows the most effective way to curb smoking is to increase the price.
He was asked today if changes to tobacco's excise tax could happen as early as this year's budget.
Mr Key says it is interesting that surveys have shown that even smokers want to see tougher measures to convince people to give up.
