It's important to remember that Mr Mallard has broken no rules in selling his tickets on Trade Me. Homegrown is not covered by the Major Events Management Act.
However, perception is everything in politics, and Mr Mallard must have known that would not have been a good look.
It's a throwback to the bad old days.
It's also the last thing new Labour leader David Shearer needs at a time when he is trying to preach the message of rejuvenation in his party's ranks.
Whether Mr Mallard was or was not scalping the tickets is a matter for personal interpretation, but the MP should be taken at face value when he claims that was not his intention.
However, his subsequent claim that the buyer breached his privacy by going to the media and revealing him as the original ticket buyer is less likely to withstand rigorous scrutiny.
There's a school of thought that politicians largely abandon any claim to privacy by signing up for public office. While some may debate that view, less debatable is the hypocrisy in Mr Mallard claiming a breach of privacy when he apparently advertised the tickets using his parliamentary email address.
Despite Mr Mallard's offer to buy back the tickets, it's another unwanted distraction for Labour at a time when it would have hoped to be making political gains around the Crafar farms sale reversal, and Prime Minister John Key's controversial Radio Live appearance.
