News International "failed to co-operate" with the original police investigation into the phone hacking scandal at the News of the World, senior Metropolitan Police Officers told the Home Affairs Committee on 12 July 2011.
Assistant Commissioner John Yates told MPs he regretted his decision in 2009 not to re-open the phone hacking investigation.
However he insisted he had always told the truth to the committee, and implied that the News of the World "failed to co-operate" with the police until the start of the year.
"I can assure you all that I have never lied and all the information that I've provided to this committee has been given in good faith," he said.
Mr Yates told MPs that recent information disclosed by the newspaper would have had a "significant impact on the decisions that I took in 2009 had it been provided to us."
Peter Clarke, the former senior police officer who oversaw the original probe into phone hacking in 2006, accused News International of "prevarication" and "lies" during his investigation.
"This is a major global organisation with access to the best legal advice, in my view deliberately trying to thwart a police investigation," he told the committee.
Deputy Assistant Commissioner Sue Akers, who is leading a new investigation called Operation Weeting, was the final senior officer to give evidence.
She revealed that just 170 of more than 4,000 potential phone hacking victims have so far been contacted by the police.
She admitted there was an "awful lot to do" after revealing that the material gathered by police contains 3,870 first and second names, along with 5,000 landline phone numbers and 4,000 mobile phone numbers.
Ms Akers gave MPs her "guarantee" that she would oversee a thorough inquiry, adding: "I hope that I do not have come back here in five years' time."
