Several networks operate across multiple centres or nationwide. Most of them have resulted from the consolidation of a group of existing stations and many have changed their name over time. The Sound was previously Solid Gold. TAB Trackside was previously LiveSport, BSport and Radio Pacific. Mix (formerly Mix 98.2) is a reincarnation of Easy Mix, Viva and Easy Listening. The now-defunct Kiwi FM was previously Channel Z. The Wolf also no longer operates.
