Mining billionaire Clive Palmer has faltered over a candidate's name while spruiking his party's election platform on the New South Wales mid north coast.

Mr Palmer was in Port Macquarie and Taree on Saturday to promote the Palmer United Party (PUP) candidate for independent Rob Oakeshott's seat of Lyne.

In a follow-up interview with ABC Mid North Coast's Michael Spooner this morning, the businessman became agitated after being quizzed about his party's candidate's name.

He told the presenter the candidate "lives in Lyne" and has "done a really good job".

But when asked again what the candidate's name was, Mr Palmer asked for another question.

"Well I'm not going to be quizzed by you on rubbish," he said before hanging up the phone.

Palmer United Party had originally endorsed Simon Rock from Taree who has decided not to run.

Port Macquarie resident Troy Wilkie is now the PUP candidate and he has brushed off the incident.

Mr Wilkie says he heard the interview but was not embarrassed by what happened.

"Look honestly it doesn't faze me in the slightest, the fact is I saw Clive on Saturday, that was the third time I'd met him and we spent the whole day together," he said.

"He said my name tens of times throughout the day and we had a good chat and there were more important things to discuss than remembering name games sort of thing.

"We were talking about national issues rather than trying to infuse that into his head."

Mr Wilkie is currently listed on the PUP website as the candidate for Sydney and describes himself as a freelance actor and property developer.
