The mounting Government pressure on people to quit smoking has seen Mr Lawrence's business branch out into a cafe and gift lines. On July 22, every tobacco product will have to be hidden from public view.
He was bitter at how pre-budget hints had needlessly spooked Tauranga smokers into buying up cartons of cigarettes, so much so that he had nearly run out by the time the Budget was announced yesterday.

Labour's Sue Moroney welcomed the tax hike, saying that all the evidence showed it would lead to an immediate fall in the numbers of smokers. ASH communications manager Michael Colhoun said the Government had shown a fantastic commitment to reduce smoking.
