Hunt told a PRWeek conference that he would publish all documents relating to his expenses on his website.
He said he was taking the action because he had been receiving ‘dozens of emails a day from constituents' enquiring about his expenses.
Hunt, the shadow secretary of state for culture, media and sport, is thought to be the most senior MP to make such a peldge.
His staff have spent the last week combing through spreadsheets and scanning in relevant documents. He said he expected to have all the information online today (Friday).
Hunt told the conference that the episode illustrated the changing nature of communications in the internet age, adding that politicians had to adapt to the new media environment.
He said: ‘We've got to embrace the change or we'll be swept out of business, people will consider us an irrelevance.'
Hunt was talking at PRWeek's PR On The Edge conference, which took place yesterday in central London. See next week's magazine for further coverage of the conference.
Earlier this week, independent Wyre Forest MP Dr Richard Taylor gave the BBC full access to his expense accounts. He is thought to be just one of a handful of MPs to reveal the full extent of their expense claims.
