Solid Gold FM started in Auckland on 13 October 1997 broadcasting on 93.4FM. This frequency was previously used to broadcast Kool 93, a station that played a similar format to Solid Gold. After The Radio Network purchased Kool 93's parent company, Prospect Media Ltd, the Commerce Commission ruled that The Radio Network had to sell or dispose of some of their Auckland frequencies as a condition of the sale, and as a result they closed Kool 93, with the frequency going to Energy Enterprises.
