From today, it's illegal for shop owners to have tobacco products visible to members of the public.
As a smoker myself, who has tried many times to kick the habit, I support the move.
The change is a result of last year's amendments to the Smoke-free Environments Act that make it illegal to have tobacco products visible to members of the public, either inside or outside their premises, or use any retail or trading name signifying tobacco products are available for sale.
Tobacco retailers will have a responsibility to ensure they meet the requirements of the Act. Those who do not may face prosecution and a fine of up to $10,000.
Associate Health Minister Tariana Turia has said the law change would remove the loophole of tobacco displays.
