The Radio Network made two attempts to purchase C93FM Limited, in March and May 1997; both were rejected by the Commerce Commission on the basis that they would give the company a dominant position in the Christchurch radio market.

Following the sale of C93FM Limited to Radio Otago, C93FM was started in Dunedin by rebranding local rock station 93Rox as C93FM.

In 1999 Radio Otago was sold to the Radioworks and in Invercargill and Dunedin C93FM was replaced with network station The Rock.

The changes made to C93FM were not popular, and the station failed to attract new listeners as a result.

C93FM went off the air in April 2001 and the 92.9FM frequency was taken over by Solid Gold, which later became The Sound in 2012, changing back to a classic rock format.
