SkyCity is targeting smokers with an expanded casino area designed for customers who want to have a cigarette while gambling.
Two linked applications have been approved by the Gambling Commission allowing the Auckland casino to make changes to create new smoker-friendly areas.
It follows comments by chief executive Nigel Morrison in February in which he said smoking laws in Australia were more attractive to gamblers from China and Malaysia.
"If we could allow them to smoke, we could generate a lot more income."
