The Rock was formed by Joe Dennehy GM, Grant Hislop PD, and Martin Dempster.The original line-up included Chris Clarke on breakfast (replaced by Mark Bunting after 2 months) and Roger Farrelly on Drive.

Originally, The Rock 93FM was based in the basement of Radio New Zealand Broadcasting House in Hamilton, headquartered in the studios for ZHFM.

The station purchased a collection of FM frequencies from the Christian Broadcasting Association and transferred them to Nevada.

Later that year, Energy Enterprises and Radio Otago merged to form RadioWorks; as a result, the station was networked into the South Island.

Christchurch C93FM listeners were gutted that their local Classic Rock station had a format change and had to give way to a Network station, the phones rung for weeks with upset listeners not liking the format change to Adult Contemporary.

[5] Other DJs left, including Greenman, who went on his OE to the UK,[citation needed] Beachy (Christopher Beach) who moved into sales and Julie Moffett, who now works at RNZ.

[6] In June 2019 Bryce not only broke the world record for the longest time ten-pin bowling continuously, he also raised over $350,000 for the charity "I am hope".

Rog serves as a leader of sorts for the Morning Rumble crew, and his ongoing banter and power struggles with Bryce provide a lot of the show's entertainment.

Jono was made the victim of stunts such as 'The Human Slushy', 'The Pyramid of Fire', 'Human Coleslaw', 'Sleigh of Fire', 'The Skater Ramp of Doom', a full body wax, and giving Jono a tattoo on his bottom but not telling him that it was a love heart with the other DJs names.

A one-off 'Final Ever Do Stuff To Jono' stunt was planned and executed in September 2009, during which Jono performed a 'Mega Stunt' - riding a BMX bike down a steep slope, through pyrotechnics and a pane of glass, and finally scaling a ramp to jump over a parked ute.

The winner would travel to Ukraine to meet a girl via the "Endless Love" dating agency.

The chart order, including which bands and songs feature on the countdown, is determined by listeners via a voting system on the station's official website.
