Only 4% of alcohol sales happen after 9pm, Stuff reports. So should hours be cut? New Zealand is often said to have an alcohol problem, with one in five adult Kiwis drinking “in a way that could harm themselves or others”.

Dr Nicki Jackson, executive director of Alcohol Healthwatch, said that those light night sales tended to involve more harm. Furthermore, booze was on the panic buying list when the Delta community outbreak was announced.
