The Electoral Court has granted the Independent Electoral Commission (IEC) permission to postpone the March 3 by-election owing to current Level 3 lockdown restrictions, which prohibit political activities.
The by-election is now set for May 19.
This year 24 ward by-elections have already been postponed, owing to the Covid-19 pandemic.
By-elections previously postponed by the IEC on January 11 will also take place on May 19.
