1988 Currie Cup Division A Wikipedia
There were seven participating teams in the 1988 Currie Cup Division A. These teams played each other twice over the course of the season, once at home and once away. Teams received two points for a win and one points for a draw. The top two teams qualified for the title play-offs (along with the top team from Division B). In the semi-finals, the team that finished second had home advantage against the team that finished top of Division B, while the team that finished top had a bye through to the final. The final was then played at the home venue of the higher-placed team.
The bottom team on the log qualified for the relegation play-offs. That team played off against the team placed top in Division B over two legs. The winner over these two ties qualified for the 1989 Currie Cup Division A, while the losing team qualified for the 1989 Currie Cup Division B.
As champions of Division B, Northern Free State qualified to the semi-finals of the Currie Cup competition, where they met Division A runners-up Western Province.
In the relegation play-offs, Northern Free State beat Free State on aggregate and won promotion to Division A. Free State were initially relegated, but Division A was expanded to 8 teams and they retained their place.
