Deputy Prime Minister David Seymour publicly backed fringe micro-blogger Ani O’Brien after she published allegations about political editor Maiki Sherman, despite criticism O’Brien had not sought Sherman’s response before publication.

During a media stand-up on April 28, Seymour praised O’Brien’s Substack, declaring it “Ani O’Brien Day” crediting her with publishing allegations he claimed mainstream media failed to report.

Seymour said it had taken “one woman with a free Substack account” to publish what he described as a story that had been subject to a “conspiracy of silence” for nearly a year.

He said if the allegations were accurate they were “absolutely disgraceful” and accused the press gallery of applying a double standard by failing to report them sooner. He also suggested Parliament’s Speaker should examine the matter, including Sherman’s parliamentary accreditation.

Sherman later resigned from her role as political editor following the controversy surrounding the allegations and the intense public scrutiny that followed.

In public posts on X following Sherman’s resignation, O’Brien defended her smear and rejected suggestions she had orchestrated a campaign against the political editor.

“I have written hundreds of Substack articles on political matters. This is the one they seized on,” O’Brien wrote. “I wrote an article about something that happened just like I do every week.”

O’Brien said she never called for Sherman to be sacked and described the incident as an “open secret” within political and media circles. She argued New Zealand’s media culture had normalised “career-ending moral scrutiny” for public figures and said the same standards were now being turned inward.

The resignation also sparked debate across social media over media standards and the Whale Oil-era smear tactics operating outside traditional editorial processes.

In a public statement posted on May 8, Sherman acknowledged using “an offensive comment” toward another journalist during an after-hours function in the Finance Minister’s office the previous year.

Sherman said there was “no excuse” for the language she used and confirmed she apologised the following morning to both the journalist involved and the minister. She also said the remark came in response to “deeply personal and inappropriate remarks” directed at her earlier that evening.

Seymour’s endorsement drew criticism as the allegations were published without an apparent right of reply for Sherman, a basic expectation in standard journalistic practice.

By elevating the Substack and attacking mainstream reporters, Seymour is accused of backing a one-sided smear campaign against Sherman while condemning others over media standards. His remarks followed criticism suggesting he had given credibility to a partisan attack piece and helped legitimise a biased publication that did not give its main subject a right of reply.
