United Future leader Peter Dunne was pinged for going 5km over the speed limit.

Internal Affairs Minister Peter Dunne has made light of getting two speeding tickets on the same day.

Dunne has come clean about a 2013 driving offence on Twitter, as a result of a Newstalk ZB Official Information Act request asking for the information from all ministers about their self-drive cars.

The minister said he did not take the request for information on the infringements seriously, saying: "It's a trivial issue. No big deal".

Shock! Horror! Thanks to an OIA inquiry by @felixmarwick the fact I was caught twice in March 2103 doing 55k in a 50k area has come to light — Peter Dunne (@PeterDunneMP) May 12, 2016

He said it was a capital offence and he's paid the fine.

Dunne was caught twice in one day, going an "awful" five kilometres over the speed limit, going down Dowse Drive in Maungaraki, Lower Hutt.

"I don't really think in the grand scheme of things the fact that I was doing 5k over the speed limit's a massive issue," he said.

"It's borne a huge scar on me," he said, before a slight chuckle.

He continued to make light of the issue later on in the day.

"I'm deeply shocked, I have been taking counselling because this is a very serious state of affairs and I'm just ashamed of the fact that you've exposed me as a serial traffic offender.

"Most New Zealanders would treat this as the joke that it is."

The OIA request had been declined and was being looked at by the Office of the Ombudsman.

Questions such as "did you take the OIA seriously?" and "do you think the public cares about this issue?", Dunne labelled "mad". He has since apologised for offence that caused.

Dunne tweeted that the fines "gnawed" at his conscience so much that he had to see his therapist to confess his "heinous crime" and accept society's shaming.

He has caused controversy with his tweets in the past - he's likened NZ First to the KKK and posted a picture supporting a serial killer.
