"If you go back 10 or 15 years there was quite a stigma about drinking light beer. Now it is very, very accepted.
"This year we are seeing that trend continue."
The trend of people staying home was not new and "certainly driven" by cheap supermarket alcohol.
"The competition for the market isn't really one bar down the road. The competition is whether or not I can get you to come out of your living room, where you have your big television, cheap supermarket beer and pizza delivered to your door."
Shed 2 On The Quay owner Dennis Buckley said since the tougher law there had been an increased trend toward sober drivers and a bigger trend toward the consumption of low-alcohol beer and wine by local patrons.

About 70 per cent of his Ahuriri customers were tourists and winter would "definitely" be the time to judge whether the changed drinking limits had an effect on locals' drinking patterns. Tourists "had their own habits" and often did not need to drive after drinking because they were staying locally. "It is probably going to be after Easter before we get a handle on it."
Of the increased consumption of low-alcohol drinks, ginger beer had the greatest increase "which is good for the local people because it is made in Hawke's Bay".

"People are becoming more sensible and we have functions where we promote sober drivers," the former Magpies lock said. No less money was going across the bar, he said.
"Till-wise we are selling more low-alcohol beer and low-alcohol cider, a lot of coffee and a lot of snacks.
"If they are not drinking, they are eating - our steaks and burgers are to die for.
"We might get a group that has come down specifically because the food is so good, and they'll have a coffee or a ginger beer.
"We have groups of locals that have their two nights a week here and in their group they'll always have a sober driver."
