History
For much of the 2000s, Whakaraupō/Lyttelton had its own voice on the FM dial: Volcano Radio 88.5FM, broadcasting from studios in Shadbolt House on Norwich Quay. Run entirely by volunteers and self-described as “volunteer community radio at its best,” Volcano Radio wove itself into the fabric of the port town, giving local musicians, DJs and talkers a platform that mainstream Christchurch radio could never provide.
The February 2011 Canterbury earthquakes changed everything. Shadbolt House — the former Harbour Board building that had housed Volcano Radio’s studios — was left structurally compromised. The station attempted to continue broadcasting from a remote location while engineers assessed the building, but by October 2012 Shadbolt House was demolished, its absence reshaping the Lyttelton waterfront skyline and leaving the community without a local station.
The silence did not last long. In 2013, Rotten Radio came to life on 107.7FM, picking up the thread Volcano Radio had dropped and carrying it forward under a different technical arrangement. Where Volcano Radio had held a standard broadcasting licence, Rotten Radio operates under a General User Radio Licence (GURL) — a regulatory framework administered by the Ministry of Business, Innovation and Employment that permits very low-power FM transmission on designated guard band frequencies without the need to apply for a specific broadcasting licence. In New Zealand, the upper guard band runs from 106.7 to 107.7MHz; Rotten Radio sits at the top of that range, transmitting at the permitted maximum of 1 watt. The coverage area is local and intentionally modest, reaching across the harbour town without spilling into neighbouring broadcast zones — a requirement of the licence.
This guard band model, largely invisible to mainstream radio listeners, has quietly sustained a handful of micro-community stations around New Zealand. It requires no government coordination and no registration — only that broadcasters avoid interfering with licensed stations, broadcast contact information hourly, and refrain from simulcasting another station within a 25km radius. For a small, arts-rich community like Lyttelton, it is a near-perfect fit: low cost, locally focused, and free from the commercial pressures that shape larger licenced broadcasters.
Rotten Radio has operated in the volunteer spirit of its predecessor, with a roster of local DJs and broadcasters bringing eclectic, underground and experimental programming to the airwaves. The station has a presence on Mixcloud, where recordings of many shows can be found, and has cultivated a loyal local following. Among those connected to the Lyttelton experimental music scene who have been associated with the station is Bruce Russell — guitarist with noise-rock trio The Dead C and founder of the Xpressway label, who has lived in Lyttelton since 1994. Russell had previously broadcast a podcast on Volcano Radio, and the experimental music community that has long made Lyttelton its home has remained part of the station’s character.
In January 2017 the station launched a crowdfunding campaign on PledgeMe with the goal of funding a year’s worth of internet broadcasting fees — hoping to take the station’s signal beyond Lyttelton and give its music and arts programming global reach. The campaign did not meet its target, but the attempt reflected the ambition and community energy behind the project. Lyttelton, as the campaign put it, is “full of great music and music lovers,” and the station’s supporters wanted the world to hear it.
In October 2017, Rotten Radio celebrated five years on air with a fundraiser night billed as a night of “balls to the walls rock and roll” at the Hellfire Club in the British Hotel. The event featured a reunion performance by local band Asian Tang — reformed especially for the occasion — alongside the Opawa 45s and MEDaL (a new project from Mark Whyte and Dave Mulchay), with sets from the full Rotten Radio DJ lineup filling the gaps. It was a characteristically grassroots celebration: loud, local and resolutely underground.
The station continues to broadcast from Lyttelton, maintaining the tradition of community radio in the port town that stretches back, in one form or another, to the earliest days of FM broadcasting in the area. Its very existence — unlicensed in the conventional sense yet entirely legal, tiny in signal strength yet significant in community reach — says something about what local radio can still mean in a media landscape dominated by national networks and streaming platforms.
