The deals, which will see NME hosting a combination of stages and signing tents, will allow the weekly music title exclusive access to bands, stages, and backstage gossip.
As part of the deal, the magazine will get ticket giveaways and VIP access for prizewinners, and will be allowed to organise on-site advertising, flyers, stickers and sampling efforts.
The three-year contracts were negotiated by IPC Ignite!, the men and music division which publishes NME, with Mean Fiddler, which runs Reading and Leeds; DF Concerts, which runs Scotland's T in the Park; and SJM Concerts, Metropolis Music and MCD Productions, which run the Virgin-branded V festivals.
Neil Robinson, publishing director at IPC's music titles, says: "Collectively, these three events reach more than 500,000 people a year and have been proven over and over again as the best place for the NME to be at the heart of its readers' summer.
"We've been doing deals with these guys for years but this is the first time that we've actually structured long-term contracts."
For this weekend's Glastonbury Festival, the NME has launched a one-off magazine, which will see it draw on its coverage of the event from its launch in 1970, offering readers never-before-seen pictures.
