Bars and pubs in Wanganui are already working hard to counter any loss in trade due to the new alcohol limit.
The bill came into effect on Monday, lowering the breath alcohol limit for drivers aged over 20 from 400mcg of alcohol per litre of breath to 250mcg. The limit for those under 20 stays at zero.
Caroline Norton, Wanganui branch president of Hospitality New Zealand, said bars and pubs were making the necessary changes in order to keep customers going to their venues.
"People now are becoming more conscious of alcohol and driving," she said.
"In some instances, it will affect people but it's just like anything - just like the no-smoking - some people thought 'Oh, everyone is going to leave us', but you adjust to it accordingly."
