North Melbourne were eventually faced with a "simple decision" to end Tarryn Thomas' time at the club after ongoing concerns around his behaviour towards women, club football operations manager Todd Viney had said.

On Tuesday, the AFL imposed a lengthy ban on Thomas following an investigation into recent allegations made against him, with the Kangaroos moving to show the 23-year-old the door as a result.

Thomas was twice made to step away from Arden Street following a string of off-field incidents and allegations of concerning behaviour - later returning to senior football in 2023, before the most recent claims made by a woman last month.

Viney said he had seen pieces of the allegations against Thomas but he would not go into detail.

The Kangaroos had previously set up behavioural and training programs for the footballer, with the AFL handing down a requirement for him to have "undertaken and/or be satisfactorily progressing" with a program before returning to football at any level.

Both Viney and North Melbourne chief executive Jennifer Watt said the club's commitment and effort to trying to help Thomas were no longer merited.

"The club has provided Tarryn with significant time, resources and support but we've now arrived at a point where the individual's needs don't match those of the club," Watt said on Thursday.

"We know Tarryn needs help – for himself and for the women in his life – but it's clear the path we've taken over the past 12 months hasn't had the desired impact.

"To that end, we have made the decision to end Tarryn's time at North Melbourne."

In a letter to members, North president Dr Sonya Hood said "It was a complex and difficult situation but we were all united in our determination to get the best outcomes for Tarryn and those around him".

"Tarryn came back to the club midway through last year pledging to be better," Dr Hood said.

"We are all bitterly disappointed that he has relapsed. And he is now out of chances."

Speaking to the media shortly after the announcement, Viney said "hand on heart" he believed the club had gone to great lengths, hoped the fallout would serve as a wake-up call, and that on departure Thomas was aware "he'd put himself in this position".

He said from his view "there are two Tarryns"; one day-to-day and one when made to grapple with relationship issues.

Viney said Thomas had become a distraction within the club, and that club staff and AFLW players were kept across any updates around Thomas in recent periods.

"He was skating on really thin ice. On the back of the findings, the suspension, I think he saw the writing on the wall," Viney said.

"It did really become a simple decision."

A decision has not been made on whether Thomas will have his current contract, in its final year, paid out.

In their own statement, the AFL Players' Association said "we would like to reiterate that disrespectful behaviour towards women, in any form, is unacceptable".

"Tarryn has some challenges that he needs to address, and the AFLPA will provide him with access to tools that will assist him, while continuing to focus on his wellbeing,"AFLPA chief executive Paul Marsh said.

"Tarryn, like any playing member, has full access to our programs and services."
