[5][6] Notable hosts include Plunket, Otago Regional Council member Michael Laws, sports broadcaster Martin Devlin and Leah Panapa.

[11] The station has been described as aimed to "agitated audience on topics they feel journalists have ignored, like Three Waters and co-governance", promoting the idea that mainstream media has been "poisoned" by the New Zealand Government's Public Interest Journalism Fund.

In addition, former National Party press secretary Ani O'Brien served as The Platform's digital engagement editor until a workplace dispute with Plunket.

[13] Notable guests have included columnist Chris Trotter, blogger Martyn "Bomber" Bradbury, former National Party leader Don Brash, former Dominion Post editor Karl du Fresne, ACT Party leader David Seymour, New Zealand First leader Winston Peters, Labour Party Member of Parliament (MP) and Prime Minister of New Zealand Chris Hipkins, former Labour MP Michael Bassett, Counterspin Media founder and right-wing activist Kelvyn Alp, Voices for Freedom spokesperson Alia Brand, anti-vaccine influencer Chantelle Baker, former All Blacks coach Steve Hansen, and Team New Zealand sailor Grant Dalton.

[15][5] In September 2021, veteran broadcaster Sean Plunket announced that he would start his own online talkback radio station called The Platform, which he said would promote free speech, democracy and debate.

[18][19][17] In early February 2022, Plunket confirmed that former Newstalk ZB sports broadcaster Martin Devlin, former National Party MP Michael Laws, and Leanne Malcolm would be joining The Platform as hosts.

[16] Plunket and his co-hosts were also joined by digital engagement editor Ani O'Brien, who had previously served as press secretary to former National Party leader Judith Collins.

[5] In November 2023, The Spinoff reported that The Platform founders Wayne Wright Jr and Sean Plunket had met with NZME CEO Michael Boggs in late October 2023 to discuss a possible relationship between the two media companies.

In response, Penfold likened Platform founder Plunket to American right-wing broadcaster and conspiracy theorist Alex Jones.

[22] According to The Spinoff journalist Duncan Greive, The Platform had hosted several anti-COVID mandates and anti vaccine advocates including former ACT Party leader Rodney Hide, former TVNZ broadcaster Peter Williams, and Baker.

[12] On 20 May 2024, O'Brien filed a second case against The Platform with ERA, seeking compensation for what she regarded as "unjustified dismissal" after claiming her former workplace was unsafe.

[26][27] In April 2023, Plunket attracted media attention after asking Prime Minister Chris Hipkins during a press conference to define a woman.

This was part of a recent international trend of politicians including British Labour Party leader Keir Starmer and former Scottish First Minister Nicola Sturgeon being asked in media interviews to define womanhood.

Plunket's claims were disputed by Stuff's owner Sinead Boucher, who stated that the company did not have a financial relationship with Ngāi Tahu and suggested that the rumors were motivated by misogyny.

Radio Aotearoa's owner George Ngatai confirmed that The Platform would retain editorial control over its content, including the popular Sean Plunket and Michael Laws shows.
