Councils are notifying businesses and the community about changes to the Tobacco Act that ban smoking in all outdoor areas where food can be served.
This includes footpath dining areas outside stores, courtyards and beer gardens during times when food can be ordered.
The tobacco reform also bans smoking outdoors at food fairs and festivals where the primary activity is the supply of food.
It will also regulate e-cigarettes and shisha tobacco in the same way as normal tobacco products.
The changes come into effect August 1st, 2017.
