There were six participating teams in the 1989 Currie Cup Division B. 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 Division B finals, played at the home venue of the higher-placed team.

The winner of the final also qualified for the 1989 Currie Cup Semi-Final.

The top team on the log qualified for the promotion play-offs. That team played off against the team placed seventh in Division A over two legs. The winner over these two ties qualified for the 1990 Currie Cup Division A, while the losing team qualified for the 1990 Currie Cup Division B.

The bottom team on the log qualified for the relegation play-offs. That team played off against the team that won the Santam Bank Trophy Division A over two legs. The winner over these two ties qualified for the 1990 Currie Cup Division B, while the losing team qualified for the 1990 Santam Bank Trophy.

As champions of Division B, Western Transvaal qualified to the semi-finals of the main Currie Cup competition, where they met Division A runners-up Western Province.

In the promotion play-offs, Western Transvaal were due to meet Eastern Province, but play-off games were not played. At the end of September 1989, the South African Rugby Board announced that South West Africa would not play in the 1990 Currie Cup competition and that Western Transvaal would be automatically promoted. Despite suggestions that South West Africa would be allowed back into the Currie Cup, South West Africa later voluntarily withdrew, due to uncertainty arising from Namibia gaining independence.

In the relegation play-offs, Eastern Free State conceded the second leg to Boland, who won promotion to the Currie Cup Division B. Eastern Free State were initially relegated, but due to the Currie Cup Division B's expansion to 8 teams, they eventually retained their place.
