"Make Ardern Go Away" hats have returned to Trade Me after the company removed the listings.
The hats are designed in the style of US President Donald Trump's red hats, with prominent white writing on the front.
"This is a political statement. If you're not happy with your current oppressors, this is the item for you," the seller, realnzmaga, says.

Another seller is offering "Make Ardern Go Away" stickers too.
"Just a simple, clear statement to express your view of our part-time PM," they say. "Get in before your Free Speech is banned."
Two Trade Me accounts selling 'Make Ardern Go Away' products were suspended in July by the company.
One of the men was told by Trade Me he was suspended due to an "intellectual property" issue, while the other was told it was due to the nature of his account.
But Trade Me later backtracked, with Trade Me head of trust and safety George Hiotakis admitting "we did get it wrong".
"When we've gone and reviewed this it's simply been human error," he told Magic Talk's Sean Plunket in July.
"It has nothing to do with the cap and with the political message, it is related to how they have their accounts set up."
In a statement to Newshub on Monday, Trade Me reiterated that the items were removed due to account issues, which have since been resolved.
"Those stickers and hats are allowed onsite as they're legal and they don't breach our T&Cs," a spokesperson said.
According to Sunday's Newshub-Reid Research Poll, both Jacinda Ardern and Labour have sunk in the polls.
Newshub political editor Tova O'Brien says Labour and its leader suffered a "parallel plummet" - Labour down 9.2 points and Ardern 10.6.
Most of the drop in party support went to National, which is now ahead of Labour with 43.9 percent - up 6.5. National and ACT are now only a few seats away from wresting control of Parliament.
"It just goes to show how inextricably linked Jacinda Ardern's polling is with that of the Labour Party," O'Brien told The AM Show on Monday morning. "She is the magic weapon of the Labour Party - the Labour Party needs her."
