Three Northern Territory drive-through bottle shops have introduced a policy of refusing to sell cask wine to customers without cars amid continuing issues with heavy drinking and alcohol-related harm.

Beer Wine and Spirits (BWS) has begun trialling the rules at its stores in Parap and Palmerston, and at Darwin Airport.

Signs in the stores put up ahead of the ban said that the move was done "to assist the community in minimising the alcohol-related harm".

But Doctor John Boffa from the People's Alcohol Action Coalition said the policy was flawed.

"All it leads to is people getting in taxis and coming through to get their grog and getting out of taxis at the other end," Mr Boffa said.

"In fact, when this was done in Alice Springs we had the absurd situation where taxis lined up, people would get in, get their grog, and get out on the other side," he said.

Alcohol-related harm has been a major issue in the NT, with high rates of deaths among Indigenous people attributed to heavy drinking.

The rate of Indigenous children in the jurisdiction with foetal alcohol syndrome up to 4.7 per 100,000, about seven times higher than the Territory's general population.

Drinking has also been implicated in nearly 60 per cent of assaults in Darwin, with new crime statistics showing alcohol-related assaults were up 4.8 per cent in the 12 months to December.

NT Police said there had recently been a rise in levels of anti-social behaviour at take-away alcohol shops, but this was usual during the wet season holiday periods.

The Labor Party in the NT has repeatedly called on the ruling Country Liberal Party (CLP) to re-introduce the Banned Drinkers Registry (BDR).

That was a system Labor introduced when in power, but was later scrapped by the CLP, whereby people buying take-away alcohol had to have identification scanned, with problem drinkers prevented from making the purchases.

Police Minister Peter Chandler said there were no plans to bring back the BDR.

"During the 2011-12 financial year, while the BDR was in operation, 431 people had eight or more protective custody episodes," Mr Chandler said.

"In one case an individual on the BDR was taken into protective custody 117 times in 12 months by police but nothing was ever done to help them," he said.

A report from the ABC Fact Check unit found that there was a rise in alcohol-related emergency admissions to NT hospitals by 80 per cent after the register was scrapped, but this was part of a trend that began before the register was removed.
