The Christchurch City Council has agreed to look into introducing an alcohol ban on Cup Day in the area surrounding the Addington racecourse.
The New Zealand Trotting Cup, held in November, traditionally draws large crowds of punters and causes headaches for the police.
Addington Event Centre general manager Brian Thompson requested the move, saying the ban would create a safer environment for race-goers.
He told a community board it would help with problems caused by people pre-loading with alcohol prior to entering the race course and becoming difficult to control later in the afternoon.
Police have said they would support a ban.
