The aim of the shortened hours is to limit the harm alcohol causes in our community but no one seems to know exactly how or to what extent.
Spokeswoman for Countdown supermarkets Kate Porter, who fought the move, said 98 per cent of shoppers who bought alcohol also bought food.
I agree with her call for the councils to provide evidence that stopping shoppers buying alcohol after 9pm would reduce harm.
If the competitive advantage is a concern, why not allow liquor stores to open until 10pm, if they wish.
For those who want to abuse it, alcohol is readily available throughout the day and I struggle to see how an additional hour of trading is going to impact on their decision to drink to excess.
It is an issue of personal responsibility.
I support rules around the sale of alcohol being enforced at all liquor outlets.
Anyone who looks under 25 should have to provide identification and intoxicated shoppers be denied service.
I also agree with liquor bans in community areas, especially those where children and families spend a lot of time, and tough drink-driving laws.
There is only so much the Government and local councils can do to protect people from themselves.
Roping off the aisles in supermarkets will only frustrate busy shoppers while the drunks remain happily oblivious to the change.
