[3] Prior to his television work Bradbury was the host of the 'Late night talk lounge' on defunct alternative music station Channel Z from 1996 until 1998, as well as a regular DJ during various time slots.
After a regular guest spot on RNZ's show The Panel, the network withdrew an invitation for Bradbury to return as a panellist.
[5] According to Radio NZ "Mr Bradbury’s comments were inconsistent with information that he had provided to programme producers before going on air.
It was made clear to him that while his invitation to appear as an occasional guest on The Panel was being withdrawn, it was not a 'lifelong ban' and it did not apply to other Radio New Zealand programmes".
[10] On 23 September 2016, Martyn Bradbury testified as a defence witness in Jordan Williams' defamation trial against Colin Craig, the former leader of the Conservative Party.
Williams, the co-founder of the New Zealand Taxpayers' Union had filed a defamation suit against Craig after the latter had produced a pamphlet entitled "Dirty Politics and Hidden Agenda" attacking Williams, the right-wing blogger Cameron Slater, and a dissident Party member John Stringer.
