Casual drinking at cafes and restaurants tomorrow and Easter Sunday is out.
"On Good Friday you are not allowed to consume alcohol on the premises unless you are there for the purpose of dining," said a Nelson City Council spokesman.
Previously the restriction applied to pubs and taverns but new alcohol legislation has been extended it to restaurants and cafes.
The same rule also applies to Anzac Day before 1pm.
The council has written to cafes and restaurants outlining the new rules.
Police say they will be visiting bars and patrolling liquor ban areas over the holiday weekend.
Driver behaviour will also be closely monitored as part of national Easter road policing operation Crossroads and the 4kmh speed tolerance will be in force. Any driver stopped could expect to be breath tested, said Tasman District Commander Superintendent Richard Chambers.
As part of Operation Unite, a joint initiative with Australian police, police here will be encouraging people to re-think how they host gatherings at home, how much they are drinking and their behaviour during and after drinking.
"We want to minimise the opportunities for alcohol related harm and road trauma this weekend," he said. Operation Unite and Operation Crossroads will run from 6pm tonight until 6am Monday.
