Hardwick's press conference in Darwin reached a flashpoint when the Suns coach was asked about team manager Mark Opie on Thursday.
Opie is subject to an AFL integrity unit investigation after a Crikey report revealed he is a co-founder of registered bookmaker Okebet.
A terse Hardwick said Opie would continue to fulfill his role at the club and turned the line of questioning onto the AFL.
"Well, at the end of the day, is it a good look for the AFL to be sponsored by Sportsbet? All these sorts of organisations?" Hardwick said.
"You want to start talking about conflict in AFL? I'm just here to talk about footy."
Hardwick's comments come less than a fortnight after Sportsbet cut ties with AFL umpire Nick Foot.
Foot was working for the betting agency's horse-racing coverage, with his employment revealed in the lead-up to Zak Butters' tribunal case for umpire abuse.
Sportsbet confirmed in the aftermath any current sports officials or administrators would no longer feature in their programming.
Former players and media pundits Luke Hodge and Kane Cornes have also stepped down from the All-Australian panel due to their links with TAB and Sportsbet, respectively.
Asked if it was inappropriate for the club to allow Opie to continue working while being investigated, Hardwick said: "I've answered the question.
"At the end of the day he's there to perform a role, and he does that role with our football club.
"Conflicts of interest within AFL circles are prevalent everywhere, as we're seeing at the moment, so that will get dealt with in due course."
Preparing for the club's Sir Doug Nicholls Round clash against Port Adelaide on Friday, Hardwick claimed the line of questioning was "tearing everything down".
"I'm here to talk about the game and what it means to the Northern Territory people," Hardwick said.
"If you want to take it down that path, talk to the CEO who controls the business aspect of the game.
"Are we clear? Are we clear? Are we clear? Let's be clear ... We love coming to the Northern Territory, but people like this guy (journalist) want to sit there and make it everything about everything else.
"What we're very good at in society at the moment is bringing everything down, tearing everything down."
